If these instructions are not followed when installing, operating and maintaining the system, Enertech’s commitment under the applicable warranty terms is not binding CTC EcoHeat 400 7 General Information Your home's heating installation The House Heating Curve The heating curve is the central part of the product’s control system. It is the heating curve which determines the compensated flow temperature requirements for your property dependent upon the outdoor temperatures. It is important that the heating curve is correctly adjusted, so that you achieve the best operation and economy possible. One property requires a radiator temperature of 30 °C when the outdoor temperature is 0 °C, whilst a different property requires 40 °C. The difference between different properties is determined by the radiator surface area, the number of radiators and how well insulated the house is. ! The set heating curve always takes priority. The room sensor can only increase or decrease the heat beyond the set heating curve to a certain extent. Where operating without a room sensor, the selected heating curve determines the flow temperature supplied to the radiators. Adjustment of Default Values for the Heating Curve Your home’s heating installation You define the heating curve yourself for your property by setting two values in the product control system. This is achieved by selecting the options Inclination or Adjustment under the Installer/Settings/Radiator system menu. Ask your installer to help you set these values. It is extremely important to set the heating curve and, in some cases, unfortunately, this process may take several weeks. The best way of doing this, upon the initial start-up, is to select operation without any room sensor. The system then operates using the outdoor temperature reading and the property’s heating curve only. During the adjustment period it is important that: • the night reduction function is not selected. • all thermostat valves on the radiators be fully opened. (This is to find the lowest curve for the most economical use of the heat pump.) • the outdoor temperature is not higher than +5 °C. (If the outdoor temperature is higher when the system is installed, use the factory set curve until the outdoor temperature falls to a suitable level.) • the radiator system is operational and correctly adjusted between different circuits. Appropriate Default Values During installation you can seldom achieve a precise setting for the heating curve instantly. In this case, the values given below may provide a good starting point. Radiators with small heat-emission surfaces require a higher primary flow temperature. You can adjust the gradient (heating curve gradient) for your heating system under the Installer/Settings/Radiator system menu. Recommended values are: 8 Floor heating only Inclination 35 Low temperature system (well insulated houses) Inclination 40 Normal temperature system (factory setting) Inclination 50 High temperature system (older houses, small radiators, poorly insulated) Inclination 60 CTC EcoHeat 400 General Information Adjusting the heating curve The method described below can be used to adjust the heating curve correctly. Adjustment if it is too cold indoors • If the outdoor temperature is lower than 0 degrees: Increase the Inclination value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. • If the outdoor temperature is higher than 0 degrees: Increase the Adjustment value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. Adjustment if it is too warm indoors • If the outdoor temperature is lower than 0 degrees: Decrease the Inclination value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. • If the outdoor temperature is higher than 0 degrees: Decrease the Adjustment value by a couple of degrees. Wait 24 hours to see if any further adjustment is required. ! If the values set are too low, this may mean that the desired room temperature is not being reached. You then need to adjust the heating curve, as necessary, following the method shown above. When the basic values have been set more or less correctly, the curve can be finely adjusted directly using the Room temp. shown on the home menu screen. CTC EcoHeat 400 9 General Information Examples of Heating Curves You can see in the diagram below how the heating curve changes with different Inclination settings. The gradient of the curve shows the temperatures that the radiators require at different outdoor temperatures. Primary Flow Temperature Curve Inclination The inclination value which is set is the primary flow temperature when the outside temperature is –15 °C. Outside Temperature Heating off, out Primary Flow Temperature Adjustment The curve can be parallel displaced (adjusted) by the desired number of degrees to adapt to different systems/ houses. Inclination 50 °C Adjustment +5 °C Inclination 50 °C Adjustment 0 °C Outside Temperature Heating off, out An example Primary Flow Temperature Inclination 60 °C Adjustment 0 °C In this example, the maximum outgoing primary flow temperature is set at 55 °C. The minimum permitted primary flow temperature is 27 °C (e.g. summer-time basement heating or the floor circuits in a bathroom). Outside Temperature 10 CTC EcoHeat 400 General Information Summer-time operation All properties have internal heat gains (lamps, oven, body heat, etc.), which means that the heating can be switched off when the outdoor temperature is lower than the desired room temperature. The better insulated the house is, the earlier the heating from the heat pump can be switched off. The example shows the product set at the default value of 18°C. This value, "Heating off, outside", can be changed in the Advanced/Settings/Heat System menu. In systems with a radiator pump, the radiator pump stops when the heat is switched off. The heating starts up automatically when it is required again. Primary Flow Temperature ºC Heating up Heating switched off ºC Outside Temperature Heating off, out Automatic or remote-controlled summer period The factory setting causes "summer" to commence automatically at 18ºC, as "Heating mode" is set to "Auto". Heating, mode Auto means automatic. Auto (Auto/On/Off) On means that the heating is on. For systems with a mixing valve and a radiator pump, the mixing valve operates to the primary flow setpoint and the radiator pump is on. Off means that the heating is switched off. For systems with a radiator pump, the radiator pump is switched off. Heating, ext. mode - (- /Auto/On/Off) Facility for remote control of whether the heating is to be on or off. Auto means automatic. On means that the heating is on. For systems with a mixing valve and a radiator pump, the mixing valve operates to the primary flow setpoint and the radiator pump is on. Off means that the heating is switched off. For systems with a radiator pump, the radiator pump is switched off. - No selection means no function when activated.

CTC EcoHeat 400 design The picture below shows the fundamental construction of the heat pump. The energy in the lake or ground is drawn up by the cooling system. The compressor then increases the temperature to a usable level. Afterwards it releases the energy for the heating system and hot water. Mains Water Connections Here you connect the property's mains water connections. The cold water is directed down to the lower part of the coil. Upper part In the upper part of the coil the water is heated to the desired temperature. Finned Coil for Hot Water EcoHeat is equipped with a well-dimensioned finned coil made of copper. A low temperature can be maintained without the risk of legionella bacteria. Electric heater A built-in electric heater acts as an auxiliary heater if the heat pump's output is not sufficient. Lower part In the lower part of the coil the hot water is pre-heated by the water heated by the heat pump. The major section of the coil is located in this part. Heat medium pump The adjustable-speed heat medium pump transports the cold water from the heating system to the condenser where the energy from the ground loop is drawn up and directed towards the heat pump. Compressor The compressor is the “heart” of the cooling system, pumping the refrigerant around in an airtight closed system. The evaporated refrigerant is compressed in the compressor. This enables the temperature to rise to a usable level. The energy is released to the heating system in the condenser. Bivalent Mixing Valve The automated mixing valve ensures that an even heat is continuously supplied to the radiator system. The valve has four ports and first collects the radiator water from the lower part, heated by the heat pump Insulation The heat pump's tank is insulated with die-cast polyurethane foam for minimal heat loss. Diverting valve The heated water from the condenser heats up either the upper or lower part of the tank. Condenser/Evaporator In the condenser the refrigerant releases its energy into the heating system. The energy is used to heat the hot water and the house. In the evaporator the heat drawn from the heat source (lake or ground) is released to the refrigerant, which is evaporated to be compressed later in the compressor. Sound insulation The cooling module is fitted with sound insulation as the compressor emits a certain amount of noise and vibrations. Brine pump The brine pump transports the freeze resistant water in the ground loop (cold side). The cold side is a closed system. Expansion valve The cooling system has a high pressure side (after the compressor) and a low pressure side (after the expansion valve). The expansion valve has the function of lowering the pressure on the refrigerant. This makes the temperature drop so that new energy can be drawn up into the evaporator. The expansion valve functions as a variable throttle valve depending on the current conditions in the cooling system. CTC EcoHeat 400 17 General Information 3.

If two radiator systems are installed, the values for both are displayed. 11 If you want to schedule a temperature reduction, you can continue to the Night reduction or Holiday submenus. You can select Room sensor No under the Installer/Define system/Radiator system menu. This can be done if the room sensor is poorly positioned, if the floor heating system has a separate room sensor or if you use a fire place or open stove. The alarm LED on the room sensor still functions as normal. 1 If a room sensor has not been installed you use this option to adjust the room temperature by trimming the flow temperature. If the extent of the trimming does not alter the room temperature enough, then you have to adjust the default setting under Installer/Settings/Radiator system. 1 Change the value in small steps every time (approx. 2-3 steps) and wait for the result (about a day) as the system is slow to respond. Several adjustments may be necessary at different outdoor temperatures, but you will gradually achieve the right setting for the property. If a fault occurs with an outdoor sensor, an outdoor temperature of -5 °C is simulated so that the house does not get cold. The product's alarm is triggered. If a fault occurs with a room sensor, EcoHeat automatically switches to operating according to the set curve. The product's alarm is triggered. Night reduction Holiday The 22 example above shows that the room temperature is 22.4 °C, but the desired value (setpoint) is 23.5 °C. Room Room temp. temp.

Use the plus and minus buttons to set the temperature you want, which gives you the “setpoint” temperature, in brackets. You can see the current value next to the brackets. If you use the fire or open stove only occasionally, the firing process can affect the room sensor and reduce the temperature supplied to the radiators. It can then get cold in the rooms in other parts of the house. The room sensor can temporarily be deselected during the firing process. EcoHeat then provides heating to the radiators using the set heating curve. The radiator thermostats reduce the heating supplied to the section of the house where a fire is burning. Com Room temp.

CTC EcoHeat 400 31 General Information Heating off, out 18 (10...30) Outdoor temperature limit at which the house no longer requires heating. The radiator pump stops and the mixing valve is kept closed. The radiator pump is activated daily for a short period so that it does not jam. The system restarts automatically when heating is required. Heating off, time 120 (30...240) The delay period before the radiator pump stops as described above. Inclination °C 50 (25...85) Inclination means the temperature your property needs at different outdoor temperatures. See more detailed information about this in the chapter on on Your property's heating installation. The value set is the outgoing flow temperature to radiators when the outdoor temperature is -15 °C. Adjustment °C 0 (-20...20) The adjustment means that the temperature level can be raised or lowered at a specific outdoor temperature. Night disable ºC 5 (-40...40) When the outdoor temperature is lower than this, the night reduction stops as too much energy is consumed and it takes a long time to increase the temperature.This menu overrides remote control. Room temp reduced/Primary flow reduced Room temp reduced indicates whether a room sensor is installed. Otherwise, Primary flow reduced is displayed. Room temp reduced -2 (0...-40) You define here how many degrees the room temperature will be reduced by during the various scheduled reduction periods, e.g. Night reduction, Holiday etc. Primary flow reduced -3 (0...-40) If there is no room sensor installed, Primary flow reduced is displayed instead. Alarm room temp ºC 5 (-40...40) When the room temperature is too low, the message “Low room temperature alarm” is sent to CTC SMS. The room sensor must be connected and activated. NB: For more information on the SMS function, see the “CTC SMS” manual. 32 CTC EcoHeat 400 For example: Inclination 50 means that the temperature up to the element will be 50 °C when the outside temperature is -15 °C, if the adjustment is set to 0. If the adjustment is set to +5, the temperature will be 55 °C instead. The curve is increased by 5 °C for all outdoor temperatures, i.e. the curve is parallel displaced by 5 °C. Example: Room temp red -2 means that the room temperature is reduced by 2 °C from its normal temperature. Example: As a general rule, a Primary flow reduced value of 3-4 °C is equivalent to a 1 °C reduction in room temperature in a normal system.

Define Remote Control Define Remote Control The remote control function in CTC's products provides a wide range of opportunities to adjust the heating externally. The function is available in CTC EcoHeat, CTC GSi 12, CTC EcoZenith i 250, CTC EcoZenith i550 PRO, CTC EcoLogic Pro / Family. This section covers the remote control, although not all of the functions are available in all products. There are four programmable inputs that can activate the following functions: • Heat pump tariff • Immersion heater tariff • Night reduction • Ripple control • Additional domestic hot water • Flow/level switch • Heating from HS1 • Heating from HS2 • Heating from HS3* • Heating from HS4* • Smart A • Smart B Terminal blocks – inputs There are two programmable 230V inputs and two low-voltage ports on the relay card (A2). Designation Terminal block name Connection type K22 A14 & A25 230 V K23 A24 & A25 230 V K24 G33 & G34 Low voltage (<12V) K25 G73 & G74 Low voltage (<12V) Open terminal block = no external effect. (Normal NO). Closed terminal block = function activated externally. Example: Night reduction is normally activated on terminal block K24. Open terminal block K24 = "normal heating" Closed terminal block K24 = Temperature reduction in accordance with night reduction The function is activated when pole positions G33 and G34 on the PCB are short-circuited *The number of heating systems varies between different products. The maximum is four heating systems. NB: Enertech AB is NOT responsible for the required heat being produced if the remote control has blocked the heating over a long period.

HP tariff When electricity suppliers use a differentiated tariff, you have the opportunity to block the heat pump when the electricity tariff is high. NB: If both the heat pump and the immersion heater are blocked, the building may be without heating for a long time. It is therefore recommended that you only block the electric heater with the tariff. Electricity tariff*. When electricity suppliers use a differentiated tariff, you have the opportunity to block the immersion heater(s) when the electricity tariff is high. NB: When combined with the air heat pump, there is a risk that the building will be without heating for a long time. Night reduction Night reduction means that you reduce the temperature indoors during scheduled periods, for example at night or when you are at work. Ripple control Disconnecting the compressor and immersion heater during a certain period which is defined by the electricity supplier (special equipment). Ripple control is a device which an electricity supplier can fit with the aim of disconnecting high current draw equipment for a short period of time. The compressor and electrical power are blocked when ripple control is active. Additional Domestic Hot Water Select this option if you want to activate the Extra DHW function. When the function is activated (by setting the number of hours) the heat pump immediately starts to produce extra DHW. You also have the option to schedule hot water production for certain times using the Weekly program function (recommended). The temperature is also determined by how the setting has been performed in the Installer/Settings/Upper tank/Extra DHW stop temp ºC menu or Installer/Settings/DHW tank/Extra DHW stop temp ºC. NB: Enertech AB is NOT responsible for the required heat being produced if the remote control has blocked the heating over a long period. 46 CTC EcoHeat 400 General Information Flow/level switch In some cases, extra protection is required due to local requirements or provisions. For example, the requirement in some areas is for the system to be installed within a water catchment area. The pressure/level switch is defined in the Advanced/Define system/Def. Heat pump menu. If there is a leak, the compressor and brine pump stop and the Flow/level switch alarm appears on the display. Heating, ext. mode HS1 Heating, ext. mode HS2 Heating, ext. mode HS3* Heating, ext. mode HS4* With remote controlled "Heating, etc. mode", "On" is selected if the heating is to be on or "Off" if the heating is to be switched off. "Auto" mode can also be selected. Read more in the section entitled "Your home's heating curve". Smart A Smart B Smart Grid offers an opportunity to control from the outside whether heating is to be calculated as normal price, low price or overcapacity. The heat pump and immersion heater can also be blocked in a way similar to "Ripple control". *The number of heating systems varies from product to product. The maximum is four heating systems. NB: Enertech AB is NOT responsible for the required heat being produced if the remote control has blocked the heating over a long period. CTC EcoHeat 400 47 General Information Smart 1.2 Grid Smart Grid The "Smart Grid" function selects different heating options depending on the price of energy using accessories from the energy supplier.

Re-installation This command re-launches the installation sequence. See the chapter on First start. CTC EcoHeat 400 55 General Information 6. Operation and Maintenance When the installer has installed your new heat pump, you should check along with the installer that the system is in perfect operating condition. Let the installer show you where the switches, controls and fuses are so that you know how the system works and how it should be maintained. Bleed the radiators after around three days of operation and top up with water if required. Boiler and radiator system safety valve Check around four times a year that the valve is working by manually turning the control. Check that water is coming out of the safety valve discharge. Mixing Valve The mixing valve is operated automatically from the control system, ensuring that the radiators reach the correct temperature, no matter what season it is. However, where a fault occurs, you can operate the valve by pulling out the knob on the motor and turning it clockwise to reduce the temperature or anticlockwise to increase it. increase decrease Draining the tank The heat pump should be disconnected from the power source when it is being drained. The drainage valve is positioned at the bottom left of the unit when viewed from the front, behind the front of the heat pump. When draining the whole system, the mixing valve should be fully open, i.e. turned anticlockwise as far as it will go. Air must be supplied to the closed system. Operation stop The heat pump is shut down using the operating switch. If there is a risk of the water freezing, all the water should be drained from the heat pump and the radiator system. The DHW circuit, which contains around five litres, is emptied by inserting a hose at the bottom of the cold water connection and then siphoning it off. No annual leakage control of the refrigerant is required 56 CTC EcoHeat 400 ! Do not forget to reset the mixing valve to automatic position. Push the knob back General Information 7. Fault Tracing/ Appropriate Measures EcoHeat is designed to provide reliable operation and high levels of comfort, as well as have a long service life. Various tips are given below which may be helpful and guide you in the event of an operational malfunction. If a fault occurs, you should always contact the installer who installed your unit. If the installer believes the malfunction is due to a materials or design fault, then they will contact us to check and rectify the issue. Always provide the product’s serial number. DHW Many want to gain maximum benefit from the heat pump’s low operating costs. The control system offers three hot water comfort levels. We recommend starting at the lowest level and if there is not enough hot water, increase it to the next level. We also recommend that you operate a regular DHW check to L8 guidelines. Check that a faulty blender valve or a shower mixer is not affecting the DHW's temperature. ! Avoid running hot water at high speeds. Reducing the DHW flow will increase the temperature of the water. The Heating System A room sensor, which should be fitted when possible, ensures that the temperature in the room is always suitable and stable. For the sensor to provide the correct signals to the control unit, radiator thermostats should always be fully open in the area where the room sensor is located. A correctly operating heating system is of significant importance to the heat pump's operation and affects energy savings. Always adjust the system with all radiator thermostats fully open. The thermostats can be individually adjusted after a few days in the other rooms. If you do not achieve the set room temperature, check: • that the radiator system is correctly adjusted and is functioning normally. that radiator thermostats are open and the radiators are equally warm all over. Touch the entire radiator surface. Bleed the radiators. The heat pump’s economical operation requires that the radiator system functions well, if you are to make good savings. • that the heat pump is operating and no error messages are displayed. ! ! Avoid placing the room sensor close to the stairway due to the uneven air circulation. If you do not have radiator thermostats on the upper floor, you may need to install them. • that there is sufficient electrical power available. Increase if necessary. Also check that the electric power output is not limited due to excessively high electricity loads in the property (load monitor). • that the product is not set to the “Max. allowed primary flow temperature” mode with a too low value. • that “Primary flow temperature at –15 °C outdoor temperature” is set sufficiently high. Increase if necessary. More can be read about this in the chapter on The house heating curve. However, always check the other points first. • that the temperature set back is not maladjusted. See Settings/Radiator system. • that the mixing valve is not in the manual position. If the heat is not even, check • that the placement of the room sensors is appropriate for the house. • that the radiator thermostats don't interfere with the room sensor. • that no other heat sources/cold sources interfere with the room sensor. • that the mixing valve is not in manual mode. CTC EcoHeat 400 57 General Information Current Monitor EcoHeat has an integrated current monitor. If the system is fitted with a current sensor (accessory for 230V 1N~), the property’s main fuses are continuously monitored to ensure they are not overloaded. If the fuses are overloaded, the heat pump will automatically reduce its power output to prevent overloading the property's supply. The heat pump may be restricted where high heating requirement levels are combined with, for example, single-phase engine heaters, cookers, washing machines or tumble dryers. This may result in inadequate heating or hot water temperatures. If the heat pump is limited, “High current, elpower redu (X A)” appears in text form in the display. Consult an electrician to determine whether the fuse size is correct or the three phases in the house are evenly loaded. Ground loop Faults can occur in the cooling unit if the ground loop has not been installed correctly, if they have not been bled sufficiently, if they contain too little antifreeze or are not designed to an adequate size. Poor or insufficient circulation can result in the heat pump triggering an alarm in the case of low evaporation. If the temperature difference between the ingoing and outgoing temperature is too large, the product triggers an alarm and “Low brine flow" is displayed. The probable cause is that there is still air in the brine circuit. Bleed thoroughly, which may in some cases take up to a day. Also check the ground loop. See also the chapter on Connecting the brine system. Check: • that the brine pump (right pump) speed value is not set too low. Try to increase this. Reset the Low evaporation alarm on the display. Where a malfunction repeatedly occurs, call in a technician to investigate and rectify the fault. If the text “Low brine temp” is displayed, the ground loop may not be large enough or there may be a fault with the sensor. Check the brine circuit temperature in the Current operation data menu. If the incoming temperature falls below –5 °C during operation, call in a technician to inspect the brine circuit. Air Problems If you hear a rasping sound from the heat pump, check that it is fully bled. Top up with water where required, so that the correct pressure is achieved. If this noise recurs, call a technician to check the cause. Unusual noise when shutting off DHW In some cases, unusual noises may be produced by the cold water, pipe work and EcoHeat due to the jolts which occur when the flow is quickly interrupted. There is no fault with the product, but the noise may occur when older outlets are used. More recent outlets are often fitted with a soft-closing mechanism. If an unusual sound comes from hard-closing dishwasher and washing machines, this can be remedied using a shock arrestor. A shock arrestor can also be an alternative to soft-closing water taps. Motor protection EcoHeat constantly monitors the compressor's operating current and an alarm is triggered if the compressor is using an unusually high current. When a fault occurs the message “Motor protect high current” is displayed. 58 CTC EcoHeat 400 ! Do not forget that the radiators may needto be bled as well. General Information The cause of the fault may be as follows: • Phase failure or mains interruption. Check the fuses, which are the most common cause. • Compressor overload. Call out a service engineer. • Faulty compressor. Call out a service engineer. • Circulation too poor between the cooling circuit and cylinder. Check the heat medium pump (left pump). • Abnormally high temperature in the brine circuit. Call out a service engineer. 7.1 Information messages Information messages are displayed when appropriate and are intended to inform users about various operational situations. Start delay Start delay The compressor is not allowed to start too quickly when it has stopped. The delay is usually 10 minutes. Heating off, radiator sys Shows that the product is operating in summer-time mode when only hot water is required, not heating. Ripple control Shows that ripple control is active. Ripple control is a device which an electricity provider can fit with the aim of disconnecting high current draw equipment requiring power for a short period of time. Not currently in use in the UK. The compressor and electrical power are blocked when ripple control is active. High current, reduced electricity (xA) • The property’s main fuses risk being overloaded due to the fact, for instance, that several appliances requiring power are being used simultaneously. The product reduces the immersion heaters’ electrical output over time. • 2h max 6kW. Electrical heaters are limited to 6 kW for 2h after powering on. The text is displayed if >6 kW is required during the product’s first 2 hours of operation. This applies after a power cut or a new installation. Tariff, HP off. Shows that Tariff HP is not active. Tariff, EL, off. This is used when a dual tariff is used with lower energy costs at set hours of the day. The heat pump can then take advantage of reduced primary energy costs. Compressor blocked The compressor is set to be shut down, e.g. before drilling or digging has been carried out for the collector circuits. The product comes with the compressor shut off. This option is selected under the Installer/Settings/Heat pump menu. Heating ext mode Rad 1 The remote control affects whether the heating is to be on or off. If the heating is switched off, the information “Heating from heating system 1/2” Smart: low price/overcap./blocking is also shown The product is operated on the basis of “Smart Grid”. Also see: “Define system / Remote control / Smart Grid”. CTC EcoHeat 400 59 General Information 7.2 Alarm messages Alarm: Wrong phase order compressor Reset alarm If a fault occurs with a sensor, for instance, an alarm is triggered. A message appears on the display informing about the fault. You reset the alarm by pressing the Reset alarm button on the display. If several alarms are triggered, they are displayed one after the other. An outstanding fault cannot be reset without being rectified first. Some alarms are reset automatically if the fault disappears. 60 Alarm Text Description Wrong phase order compressor The product's compressor motor must rotate in the right direction. The product checks that the phases are connected correctly; otherwise, an alarm is triggered. In this case, two of the phases to the product need to be changed. The power supply to the system must be shut off when rectifying this fault. This fault generally only occurs during installation. Alarm sensor An alarm is displayed if a fault occurs with a sensor that is not connected or has short-circuited and if the value is outside the sensor's range. If this sensor is significant to the system's operation, the compressor stops. In this case, the alarm is reset manually after the fault has been rectified. The alarm is reset automatically after the fault has been rectified for the following sensors: Sensor upper tank (B5), Sensor lower tank (B6), Sensor prim flow 1 (B1), Sensor prim flow 2 (B2), Sensor out (B15), Room sensor 1 (B11), Room sensor 2 (B12), Sensor brine out, Sensor brine in, Sensor HPin, Sensor HPout, Sensor discharge, Sensor suction gas, Sensor high pressure, Sensor low pressure. Motor protect compressor High/low current has been detected for the compressor. Press reset and check whether the alarm recurs. If the fault recurs, contact your installer. High pressure switch The refrigerant's high pressure switch has been triggered. Press reset and check whether the alarm recurs. If the fault recurs, contact your installer. Low brine temp Incoming brine temperatures from borehole/ground circuits are too low. Press reset and check whether the alarm recurs. If the fault recurs, contact your installer to check the dimensions of the cold side. High brine temp Incoming brine temperatures from borehole/ground circuits are too high. Press reset and check whether the alarm recurs. If the fault recurs, contact your installer to check the heat source. Excessively high brine circuit temperatures over a long period can damage the compressor. Low brine flow Low brine flow is very often due to air in the collector system, particularly just after installation. Collectors which are too long can also be a cause. Check also that the brine pump is set to speed 3. Press reset and check whether the alarm recurs. Also check the brine filter that has been installed. If the fault recurs, contact your installer. CTC EcoHeat 400 General Information Alarm Text Description Max thermostat If the heat pump has been stored in an extremely cold place, the max thermostat may have been triggered.

Mixing valve DHW (65) Install a mixing valve for the hot tap water in order to avoid the risk of scalding. Safety valve DHW (93) Fit the enclosed valve to the incoming cold water connection. Connect the waste pipe to the waste system through the waste funnel. The waste pipe must slope towards the waste system, be installed frost-free and left open to the atmosphere/without pressure. Non-return valve (48) ! Note! The waste pipe must be fitted to the waste system. Fit the non-return valve to the incoming cold water connection. Shut-off valve (94) It is important to fit a shut-off valve (94) on both the radiator's primary flow and return pipe. Boiler safety valve (92) The boiler's safety valve is fitted in the factory on the left side of the top. Connect the waste pipe to the waste system directly through the waste funnel. The waste pipe must slope towards the waste system, be installed frost-free and left open to the atmosphere/without pressure. ! NB! It is important to fit a shut-off valve (94) on both the heat pump's primary flow and the radiator's return pipe. Filling valve for radiator system (90) Fit a filling valve between the cold water connection and the radiator return pipe, or between the cold water pipe and the expansion pipe. Manometer system pressure (95) Fit the manometer on the expansion pipe or radiator return pipe. Expansion vessel connection The EcoHeat must be connected to a closed expansion vessel. The heat pump is ready to be fitted to an 18 l closed expansion vessel, positioned compactly on top of the product. The expansion vessel with the required angle connection is available as an accessory. Then connect the system manometer to the radiator return pipe. Top view 18L vessel If you choose another expansion vessel, a manometer is often included. If you use an open system, the distance between the expansion vessel and the highest placed radiator must not exceed 2.5 m in order to avoid introducing oxygen into the system. Note that no hot water circulation may be connected as it affects the function of the heat pump and the system. If the heat pump is connected together with another heat source, e.g. an existing boiler, the installations must have separate expansion vessels. CTC EcoHeat 400 65 Installation Operation without a brine system EcoHeat can be used without the brine system's cold side being connected. The heat pump then operates like a normal electric boiler with its control system providing full functionality. However, the DHW capacity is slightly lower as only the upper part of the tank is heated. Make sure that the compressor is blocked. Water taps In some cases, unusual noises may be produced by the house's pipe system and EcoHeat due to the jolts which occur when the flow is quickly interrupted. There is no fault with the product, but the noise may occur when older model outlets are used. More recent outlets are often fitted with a soft-closing mechanism. Alternatively, a shock arrestor can be fitted. Keeping the jolting to a minimum also helps avoid unnecessary wear and tear affecting the DHW system. DHW system You can connect a DHW circulation system. You can see this kind of connection in the figure below. Cw DHW pump (G40*) BV BLV VVB BLV CW DHW cTc (*G40 Not controlled by the product. Use a separate control or constant voltage on the circulation pump.) 66 CTC EcoHeat 400 Installation Pressure drop Pressure drop in mixing valve The diagram below shows a drop in pressure in the mixing valve. Start with the heat requirement in kW (e.g. 15 kW), then move vertically to the selected ∆t (e.g. 10 °C). Then move horizontally to the line for the EcoHeat mixing valve = line 6.3 DN20. The reading for the pressure drop is taken from the scale directly below (4 kPa). For EcoHeat, see valve DN20. CTC EcoHeat 400 67 Installation 10. Connecting the brine system The brine system, i.e. the ground collector loop, must be assembled and connected by a qualified tradesman in accordance with current regulations and design guidelines. Extreme care must be taken to ensure that no dirt gets on the collector hoses, which must be washed clean before being connected. The protective caps must remain in place at all times while work is in progress. The temperature in the brine system can go below 0 °C. This is why it is important not to use any water-based lubricant etc. during installation. It is also important that all the components are insulated against condensation to prevent the build-up of ice. ! We recommend that you follow the installation instructions from the local Heat Pump Association. Connections The brine system may be connected to the right, left or back of the heat pump. Cut away the cover plate on the side where the brine system is to be connected. The insulation on the inside of the cover plate has been grooved to enable an opening to be cut for the brine hoses provided. When the opening has been made through both the insulation and cover plate, carry out the installation as follows: 1. In order to protect the brine hoses, fasten the protective edging provided around the edge of the opening in the insulation plate. Adjust the length of the protective edging to suit the opening as required. 2. Attach the provided compression couplers to the cooling module connector pipes. To facilitate attachment, the upper brine pump connection may be loosened and rotated if necessary. 3. Pass the brine hoses through the opening in the side cover plates and connect them to the compression couplers. Ensure that the connections are well insulated to avoid the build-up of ice and condensation. 4. Install the collector system after this according to the schematic diagram. You can also connect the primary flow on one side and the return on the other. See the chapter on Measurement details for measurements and dimensions. The pipe between the heat pump and collector loop should have an internal diameter of no less than Ø28 mm. Brine out Brine in 68 CTC EcoHeat 400 Arrange the hoses so that the longest is the outermost. This applies whether connected from the left or right. Installation Valves You fit the valves as shown in the schematic diagram on the next page. To facilitate servicing of the cooling unit, shut-off valves should be fitted to both the incoming and outgoing connections. Fit bifurcated valves so that you can fill and bleed the collector circuit later on. Bleeding The collector circuit must not contain any air. Even the smallest amount of air can jeopardise the heat pump's operation. See the section Refilling and venting below. Insulation against condensation You must insulate all the pipes in the brine system against condensation. Otherwise, there will be a strong build-up of ice and condensation. Refilling and venting Mix water and antifreeze solution in an open vessel. Connect hoses to the shutoff valves (98a and 98b) as shown in the figure. Note! The hoses must have a minimum diameter of 3/4". Connect a powerful external pump (101) for refilling and bleeding. Then reset the three-way valve (100) and open the valves (98a and 98b) so that the brine passes through the mixing container (102). Also make sure that the valve (98d) is open. ! Use the Brine pump on 10 days function to bleed the system properly. If the heat pump is connected to the power supply, start the brine pump (103) as follows: • Go to the menu Installer/Service/Function test. • Select the Brine pump option and activate it. The brine pump runs until it is manually stopped. Allow the brine to circulate in the system for a long period of time until it is completely free of air. There can still be air in the system, even though no air accompanies the liquid out. Reset the three-way valve (100) so that any remaining air can come out. Bleed the level vessel (96) by loosening the plug on top of the level tank. Now close the valve (98a) while the filling pump continues to run. The filling pump (101) now pressurises the system. Also close the valve (98b) and shut off the filling pump. If the level in the level vessel is too low, close the valves (98c and 98d). Unscrew the plug and fill the vessel to around 2/3 full. Screw the plug back in and open the valves (98c and 98d). Pressure/level switch In some cases, extra protection is required due to local requirements or provisions. For example, the requirement in some areas is for the system to be installed within a water catchment area. The pressure/level switch is connected to blocks K22/K23/K24/K25 and then defined under the Installer/Define system/ Def Heat pump menu. If there is a leak, the compressor and brine pump stop and the Flow/level switch alarm appears on the display.

The filling equipment is represented by the parts displayed with dashes. Note! Collector hoses must have a bleeding facility as air pockets can occur. Always check the filter (99) when filling and bleeding the brine system. ! The mixing vessel and pump should be a good size. Post-installation check on brine system After a few days, you must check the fluid level in the vessel. Fill if necessary and close the valves (98c and 98d) when filling. Level/expansion vessel The level vessel should be fitted to the incoming line from the borehole or ground loop, at the system’s highest point. Bear in mind that the tank can produce condensate on its exterior. Fit the safety valve (105) as shown in the schematic diagram and fit a suitable plug to the top of the vessel. If the vessel cannot be fitted at the highest point, a closed expansion vessel can be fitted. 70 CTC EcoHeat 400 97 Installation Brine filling kit with dirt filter A filling kit for topping up, adding and filtering brine. Arrows on the valve housing indicate the flow direction. Close valves (98c and 100) when cleaning the filter. Unscrew the filter cap and flush the filter clean. When refitting, the pin under the filter holder should be fed into the designated hole in the filter housing. Top up with a little brine, if necessary, before fitting the cap. The filter should be checked and cleaned after a short period of operation. Brine The brine circulates in a closed system. The fluid consists of water and antifreeze solution. Sentinel R500 & R500C are recommended for use in the brine circuit on all CTC EcoHeat/Part heat pumps. The glycol is mixed at a concentration of slightly less than 30%, which is equivalent to fire risk class 2b and a freezing point of around –15 °C. ! ! Check the dirt filter after bleeding has been completed. The fluid must be thoroughly mixed before the heat pump is restarted. It is a CTC recommendation that around 1 litre of brine/glycol is required per metre of collector hose, i.e. around 0.3 litres of antifreeze solution will be needed per metre of hose, for a hose diameter of 40 mm. Air pockets To avoid air pockets, make sure that the collector hoses constantly rise towards the heat pump. If this is not possible, it must be possible to bleed the system at the high points. The filling pump usually manages smaller local height discrepancies. Checking brine difference When the heat pump is running, regularly check that the temperature difference between incoming and outgoing brine temperatures is not too large. If there is a large difference, one of the causes may be due to air in the system or a blocked filter. If this is the case, the heat pump triggers the alarm. The alarm factory setting is 7 °C, but 9 °C is permitted for the first 72 hours while the compressor is running, as microbubbles in the system can reduce brine flow.

Installation 1. 11. Energyfl Energyflex ex Energyflex is a collective term that describes CTC's unique opportunity for maximum flexibility and combining difference heat sources in a simple way. The most common combination is a heat pump and electric boiler. It is worth noting here that when installed the CTC EcoZenith i250 can serve as an electric boiler alone, but it can subsequently be augmented with: CTC EcoPart Heat Pump (ground source)) CTC EcoAir Heat Pump (air to water) Solar Energy The CTC EcoHeat/EcoZenith now has integrated functionality for simple augmentation with Solar Energy Pool Wood-Fired Heating Regarding wood-fired heating: The integrated "Differential thermostat function" control initiates the charge from, e.g., the existing wood-fired system or fireplace when the temperature is higher than it is in the CTC EcoHeat/EcoZenith i250 Bear in mind that it can also be a good idea to install an automatic charger that can protect the wood-fired system from condensation, etc If the wood-fired system needs more water than the 223 l contained in the product, the system needs to be supplemented with an accumulator tank. Example of wood-fired system with group of chargers ! Energyflex can also be used to draw energy, e.g. to heat a swimming pool Connecting external systems can seriously affect the EcoZenith’s operation and performance and can therefore produce undesirable effects if the system is not installed correctly. If you are unsure how to make the connection, contact CTC for suggestions on how to install the system. Schematic diagram only The installer adds expansion vessels, safety valves, etc., and sizes the system. CTC EcoHeat 400 73 Installation Introduction Energyflex - EcoSol The CTC EcoHeat and CTC EcoZenith i250 H/L have a water volume of 223 l with layered disc and solar output. Solar output (3/4) is a part of Energyflex. 223L 223L Solar output (3/4) CTC Ecoheat 400 (223L with solar output and layered disc). 223L CTC EcoZenith i250 H/L (223L with solar output and layered disc). H Solar output (3/4) H. Symbol of tank volume in CTC EcoHeat 400 and CTC EcoZenith i250. The tank in the CTC EcoHeat 400 and CTC EcoZenith i250 will be called the H-tank (main tank). Energy can be collected through the solar outputs (solar panels, wood-fired boiler) or generated (swimming pool). Available as accessories are pre-bent pipes with couplings and insulation to facilitate installation. Also available as accessories are CTC Solar Control/Expansion Card Accessory pipe kit Energyflex kit 400 fitted to H-tank 74 CTC EcoHeat 400 Installation System options, Energyflex The flexibility in the CTC EcoHeat and CTC EcoZenith i250 is optimised because the products contain functionality for five basic systems. These are: Solar "system 1" Solar "system 2" Solar "system 3" Diff thermostat function Pool Solar also offers the facility to recharge the drill hole or collect energy for an extra tank, with or without a solar coil. *The differential thermostat function can be connected to an existing PCB in the CTC EcoHeat 400/CTC EcoZenith i250, while Solar systems 1, 2, 3 and Pool require the product to be supplemented with the CTC Solar Control/ Expansion Card accessory. Explanations of system options Solar system 1 Charge from solar panels only to the H-tank (H) in the CTC EcoHeat 400 or CTC EcoZenith i250 Solar system 2 Charge from solar panels only to the EcoTank buffer tank + CTC EcoHeat 400/CTC EcoZenith i250. Solar system 3 Charge from solar panels either to X-Volume or CTC EcoHeat 400/ EcoZenith i250. Using a diverting valve, the charge is prioritised either to the H-tank in the EcoHeat/EcoZenith i250 or to the external X-volume G99 G98 B5 Diff thermostat function The differential thermostat function is used if you want to charge your EcoHeat/EcoZenith from an existing wood-fired boiler, a water-jacketed stove or another cheap heat source. The function compares the temperature in the EcoHeat/EcoZenith and the external heat source. Charging starts when it is warmer in the external heat source. NB: For certain heat sources, e.g. solid fuel boilers, automatic chargers are recommended, among other things to counteract condensation in the fire box.

CTC EcoHeat 400 75 Installation 12. Electrical installation Vessel 18 L 500 The installation and heat pump connection shall be done by an authorised electrician. All wiring shall be installed according to valid requirements. The immersion heater is internally connected by the factory and set for a 5.5 kW power output. It has equal phase loading at all power steps. Top view Supply The power supply cable is connected at (1). Length 180 cm. The CTC EcoHeat 400 400V 3N~must be connected to 400V 3N~ and protective earth. The CTC EcoHeat 400 230V 1N~must be connected to 230V 1N~ and protective earth. The group fuse size is specified in the chapter on Technical data. 1 Safety switch The installation should be preceded by a omnipolar safety switch (Category III), which ensures disconnection from all electric power sources. Circulation pump connection for radiator system (G1) The radiator pump is connected electrically to the terminal board. Electrical data: 230 V 1 N~. Internal fuse 10 A. Max thermostat If the heat pump has been stored in an extremely cold place, the max thermostat may have been triggered. You reset it by pressing in the button on the electrical switchboard behind the front panel. Always check that the max thermostat has not been triggered during installation. Symbol for max thermostat: Extra low voltage protection The following outputs and inputs have extra low voltage protection: current transformer, outdoor sensor, room sensor, primary flow sensor, return sensor, NR/SO. Connection for outdoor sensor (B15) The sensor should be set up on the house’s northwest or north side, so that it is not exposed to morning and evening sun. If there is a risk of the sensor being affected by the sun's rays, it must be protected by a screen. Place the sensor at around 2/3 of the height of the facade near a corner, but not under a roof projection or other form of wind protection. Do not place it either above ventilation ducts, doors or windows where the sensor may be affected by factors other than the actual outdoor temperature. Room sensor connection The room sensor is fitted at a central point in the house, in the most open position possible, ideally in a hall between several rooms. This is the best position for the sensor to record an average temperature for the house. Feed a three-conductor cable (minimum 0.5 mm2) between the heat pump and room sensor. Then attach the room sensor securely in a position at roughly two thirds of the way up the wall. Connect the cable to the room sensor and heat pump. 76 CTC EcoHeat 400 ! Do not attach the sensor cable permanently until you have tested where the best location is. Installation Connecting the primary flow/return sensor Fit the primary flow sensor to the primary flow pipe, ideally after the circulation pump. Fit the return sensor to the return pipe. The sensor component is at the front of the sensor unit, see diagram. • Attach the sensor using the tie strap provided. • Ensure that the sensor has good contact with the pipe. If required, apply contact paste to the front of the sensor, between the sensor and pipe, if good contact is difficult to achieve. • Important! Insulate the sensor using pipe insulation. • Connect the cables to the heat pump terminal board. Sensor Contact past applied Connection cables Pipe Tie strap Insulation Current sensor connection The three current sensors (designated current transformer on the connection block), one for each phase, are fitted on the fuse panel in the following manner. Each phase from the electricity distribution board supplying the EcoHeat is channelled through a current sensor before termination at the relevant terminal. Then connect to the boiler based on the terminal board diagram. This allows the phase current to be sensed all the time and compared with the value set for the heat pump's load switch. If the current is higher, the control unit drops to a lower heat output. If it is still too high, further reduction in output takes place. When the current has dropped below the set value again, the output will increase. This means that the current sensors, along with the electronics, prevent more power being supplied than the main fuses can tolerate. Use at least 0.5 mm2 cable.

The groundwater is pumped up to an intermediate heat exchanger that transfers the energy to the brine liquid. It is important that an intermediate heat exchanger is installed in the system. The intermediate heat exchanger prevents the product evaporator from becoming damaged due to deposits from groundwater particles and minerals, which could otherwise involve expensive work on the product's refrigerant system. Water requirements analysis should always be undertaken for intermediary heat exchangers. Local regulations and permit requirements must be taken into account. The return water is discharged elsewhere, to a drilled return flow well or similar. The brine pump (G20) and groundwater pump (G21) must be connected to run simultaneously in order to avoid risk of freezing. Also pay attention to the intermediary heat exchanger supplier's instructions. For connection information, see the wiring diagram. 90 CTC EcoHeat 400 Installation OBS! EcoAir har utegivare NTC 22k!

First start When CTC EcoHeat is delivered, the compressor is blocked to avoid it being unintentionally started. The heat pump can be installed and started before the brine circuit is put into operation. CTC EcoHeat can also be started without a room sensor being fitted as the curve which has been set then regulates the heating. Deselect the room sensor in the Settings menu. The sensor can however always be fitted for the alarm LED function. Before first start 1. Check that the heating boiler and system are full of water and have been bled. 2. Ensure that the brine system is filled with water and antifreeze and that it is bled, or ensure that the compressor is blocked. 3. Check that all connections are tight. 4. Check that sensors and the radiator pump are connected to the power source. 5. The backup heating thermostat has OFF as its factory setting. The recommended position is = Antifreeze setting, around + 7 °C. The backup heating thermostat is reset on the electrical switchboard behind the front panel. It is in the OFF position when it is turned anticlockwise as far as it will go (the screwdriver slot should be vertical). Symbol for backup heating thermostat: At the end of the installation, check the current transformer's connection. In this situation it is important that you have switched off any major consumers of electricity. Also make sure that the backup thermostat is closed. First start Switch on the power using the safety switch. The display comes on. The heat pump now asks the following: 1. Select the language and press OK. 2. Confirm that the system is filled with water and press OK. 3. Size of main fuse Choose between 10 and 35 A. 4. Specify the maximum electric heater power. Choose between 0.0 and 9.0 kW in steps of 0.3 kW. 5. Select the option permitting the compressor to operate (if the collector system is ready). When the compressor is started for the first time, it is automatically checked that it is running in the correct direction. An error message is displayed in the panel display if it is rotating in the wrong direction. Switch any two phases to change the direction of rotation. Use your hand to feel that the hot gas pipe immediately becomes warm when the compressor starts, but bear in mind that the pipe may be hot! 6. Brine pump on 10 days. 7. Specify the max. primary flow °C for radiator system 1. 8. Specify the inclination for radiator system 1. 9. Specify the adjustment for radiator system 1. If the primary flow sensor for radiator system 2 is installed, repeat steps 7-9 for radiator system 2. 10. The heat pump then starts and the start menu appears. 92 CTC EcoHeat 400 ! !
