It gets manual if the alarm occurs for the number of times set by the following parameter within one hour: par 69 hourly LP max. alarms 5 The low pressure alarm is temporarily disabled when the compressor starts in order to allow settlement of pressure. The bypass time is defined as follows: par 61 summer bypass time 12 ( 12 x 10 = 120 sec ) par 62 winter bypass time 18 ( 18 x 10 = 180 sec ) After this time every trip of the LP switch immediately stops the compressor. 10.2 HEAT LOW PRESSURE PRE-ALARM The fan, only in winter operating , can be forced at the max. speed if the evaporating pressure falls down the value defined by par 65 SetPreBP1 .

To achieve this, the corrections modify the set-point dynamically according to certain variables. For example, in the summer operation with low external temperatures, thus with reduced load, it is possible to obtain an indoor comfort with set-points even higher than the standard, thus with a higher energy efficiency Correct Set Point (es 6.7 °C) Slettet: Summer/Winter Slettet: correction Set Point (es 5.7 °C) The static set-point can be modified dynamically with two CORRECTIONS based on as many factors external to the unit: • correction based on the external temperature/enthalpy • correction based on the Water reset (signal 4-20 mA supplied by the customer) The correct set-point, to which all corrections have been added or subtracted, is identified as ACTUAL set-point and is displayed by the status n°1 ( see page 20 ) ACTUAL Set point or right ( state n° 1 ) CORRECTIO N Summer/Winter Set Point 12.1.1 CORRECTION ON THE EXTERNAL TEMPERATURE This function can be activated on the chillers only if the external air probe BT6 is installed (basic module, CN2 pin 6 and 7) Par 152 EXT. air probe presence 1 num Par 9 Comp. enabling for external temperature = 0 no compensation 1 compensates in summer mode only 2 compensates in winter mode only Slettet: Summer/Winter 3 modes compensates in both SUMMER In the summer operation with low external temperatures a reduced cooling demand is supposed. Thus, the indoor confort can be obtained even with set-points higher than the standard. In the summer operation, the correction is added to the set-point (thus it is increased while external temperature decreases. ) Max correction = par 14 ACTUAL set-point correction Par 10 External Temp. par 11 The max. value of the correction that can be applied is set by: Par 14 Max. value of summer correction The correction is active in the temperature range defined by: Par 10 External temperature for max. summer correction Par 11 External temperature for min. summer correction 6 °C 15 30 °C °C This function can be used also with a different logic: increase the set-point while the external temperature increases. In this case, the required operation is opposite the previous one; the set values are thus reversed: Par 10 External temperature for max. summer correction 30 °C Par 11 External temperature for min. summer correction 15 °C WINTER In the winter mode with mild external temperatures (e.g. 15°C) the thermal requirement is supposed low and thus the room comfort can be reached with a lower set-point, too. The correction is thus subtracted from the set-point (thus it is decreased while the external temperature increases ) ACTUAL set-point correction Correction Max. Value = par 15 External Temp. Par 13 par 12 The max. value of the correction that can be applied is set by: Par 15 Max. value of winter correction The correction is active in the temperature range defined by: Par 12 External temperature for max. winter correction Par 13 External temperature for min. winter correction 10 °C 15 -5 °C °C The above remarks apply here, too: the function can be used with a different logic: decrease the set-point while the external temperature decreases. The required operation is opposite the previous one; the set values are thus reversed.

The enthalpy correction is active in the summer operation; in the winter operation the correction is applied only on the external air dry bulb temperature (enthalpy value is not active).

The MAINTENANCE set-point thus controls the temperature of the treated water when the unit is OFF or in Stand-by. To achieve this, it activates periodically the circulation pump, it tests the water temperature and possibly activates the compressor. Par 42 Summer maintenance Set Point 20 °C Par 43 Winter maintenance Set point 30 °C It is enabled with the parameters: Par 44 Summer maintenance enabling Par 45 Winter maintenance enabling 1 1 num num With unit and pump OFF it starts counting the time: par 41 Maintenance scan time 1800 sec at the end of the time the pump is activated par 144 Pumps in maintenance starting time 120 Sec at the end of the time, if the set is not met it remains active with the compressor as long as the set is reached. 14 COMPRESSOR TIMING The number of starts and thus the wear of the compressor are reduced as much as possible by the control system with 2 parameters. The max. number of starts/hour of the compressor is limited by setting the delay between a start and the following restart of the same compressor: par 63 start time/ compr. start 360 sec The pressure equolization before the compressor restart is aided by setting the delay between a stop and a start of the same compressor: par 64 stop / start time 30 sec 15 COMPENSATIONS The compensations are aimed at safeguarding the compressor; thus they prolong compressor’s operating time and limit the number of hourly start pulse s To achieve this, the compensations add an OFFSET to the activation point of the compressor activation Level with OMPENSATION offset by COMPENSATION Activation level without COMPENSATION ACTUAL set point By means of compensation, the compressor working point is taken away from the set, avoiding too short working periods. The possible compensations are 3: Compensation on the LOAD = based on the inlet-outlet water temperature difference Compensation on the DUTY-CYCLE = base on the frequency and duration of the compressor ONOFF cycles Compensation on the DURATION = based on the compressor ON time The compensation off-set is dynamically calculated and is the sum of the instantaneous values of the active compensations. It cannot exceed the highest value among the maximum limits of the compensations; it can reach max. 3°C with the default parameters. compensations Total max value always Equal or minor than The higher singol max. values Max value Max value temp. °C Compressor start °C + + = On duration °C Singol value sum Compensation offset Max value °C on duty- On water inlet temperature Histeresys ON Compensation Offest Capacity step Actual setpoint Histeresys OFF Compressor stop 15.1 COMPENSATION ON THE LOAD The compensation is based on the average temperature difference between water inlet and outlet. LOW load HIGH load delta T °C Medium average 5 °C Medium average par 4 = 300 sec par 4 = 300 sec If the average temperature drop is 5°C, that is the compressor has always been active, the thermal load is high. If the average temperature drop is low, this means that the compressor has stopped several times, thus the thermal load is low. In this case it is possible to compensate (namely to delay the compressor start). low average temperature drop = low load = frequent compressor start pulse s + short operating periods The highest compensation corresponds to the minimum average temperature drop, namely with inlet temperature close to the set-point.

It is especially useful if the load is variable. Inlet temp.. 15.2 COMPENSATION ON DUTY-CYCLE The compensation on DUTY-CYCLE is based on the ratio : operating time Oper. time + stop time This function is based on elaborate mathematical calculations and test checks. The resulting values are thus to be meant as standard and cannot be modified. Please note that the worst conditions occur for duty-cycle values included in the range between 20% and 50% (ON time = 50 % OFF time) . 53 54 55 56 Enables compensation on duty Value of critic duty Max. value compensation on duty Time of medium duty calculation 1 20 1,5 1800 num % °C sec The compensation on the duty operates a standard optimisation of the ON-OFF cycles; thus, it is of general use and must be enabled always. 15.3 COMPENSATION ON THE DURATION The compensation on the DURATION is based on the compressor ON time. Short ON times, even if followed by long OFF periods, are critical for the compressor (lubrication problems). ON compr. with active compensation ON Average temp. drop That's why at the end of each operating cycle of the compressor the controller checks the duration (compressor ON). If the ON time is lower than 200 sec the controller increases the compensation, then it checks if ON reaches 200 sec; otherwise, it increases the compensation again. The compensation is increased max. three times the max. value. If the ON time is longer than 300 sec, the compensation is decreased with the same logic. Par Par Par Par 57 58 59 60 It enables the duration of compensation Min. operating time Max. operating time Max. duration comp. value 1 200 300 1 num sec sec °C The duration compensation has an “incisive” effect: it compensates up to 3°C. It is useful when the water content is limited. The incisiveness is detrimental to the low temperature control accuracy: in industrial applications, where a fine temperature control is required, this compensation can be disabled but a fair water quantity in the system is necessary. PLEASE NOTE THAT WITH SHORT COMPRESSOR ON PERIODS IT IS POSSIBLE TO HAVE A LOW AVERAGE TEMPERATURE DROP; IN THIS CASE, THE LOAD COMPENSATION WOULD HAVE A LIMITED EFFECT. 16 TEMPERATURE CONTROL The temperature control is based on the outlet temperature and is based on temperature drop between water inlet and outlet defined while designing the system Par 37 Summer temperature average 5 °C If the temperature drop on the system is not 5°C, it is basic to update the parameter value to the current temperature drop on the system; otherwise, the adjustment logic is distorted. The cooling/heating capacity supplied by the individual resources is defined (capacity step): single capacity step the compressor alone supplies 100% of the required power (SUMMER) double capacity step the compressor alone supplies only a part of the required power (WINTER with electric heaters) Par 72 Compressor output capacity 70 % Par 177 Output by the integration heaters 30 % The controller can activate one and only one step at a time, and only after the activation scanning time (status 4, page 20) . The activation scan time is not fixed, rather it changes according to the difference between water outlet temperature and current set-point value.

(actually, first a check on the system charged with water through the input 9 of CN1 is made; being this bridged, it is always positive). On page 22 the flow alarm management is described. 20.2 SINGLE PUMP + STAND-BY PUMP There are 2 pumps: • one operating • one in stand-by ready to start if the first one does not work roperly The stand-by pump is always the one having less running hours. THE ONLY DIFFERENCE WITH RESPECT TO THE PREVIOUS CYCLE IS A TRIAL IS MADE WITH THE STAND-BY PUMP BEFORE STOPPING THE UNIT BY FLOW ALARM ( SEE PAGE 25 ) . 20.3 VARIABLE DELIVERY PUMP The variable flow is mainly intended to assist the compressor at start, reducing the possible thermal shock caused by water temperature outside the operating limits. The speed control depends on water inlet and outlet temperature. The circulator can be: two speeds proportional depending on a diving signal • 0-10 Vdc (pump inverter) • PWM On units configured with variable flow pump (par 141 = 2) parameter 189 activates the two speeds output alternatively (e.g. 1st step with smaller pump and 2nd with bigger one), or together (e.g. 1st step one pump, 2nd step two pumps together). Par 189 Step activation mode = 0 steps in alternative with 100 ms between de-activation of one and activation of the other. =1 steps operating together, in this mode it is not necessary to manage any safety time during speed change. 20.4 CIRCULATOR PILOTED AT VARIABLE SPEED The pump speed changes according to the inlet temperature on the exchanger: COOLING for high inlet temperatures the flow is progressively reduced to get a higher water temperature drop % driving signal par 188 = 80 par 187 = 50 par 185 17 25 par 183 exchanger Inlet water temp.

Condensation is kept under control sensing only the relevant pressure (no temperature control) WATER VALVE MODULATION The valve is closed with steady compressor. When the controller requires capacity the water valve opens by the extent set by the parameter: par 104 % Fan at start 70 % This step has a duration, in seconds, equal to: par 100 Fan start pulse duration 5 sec after this time the system checks the condition of the water differential pressure switch. If it is closed, the compressor can start and the water valve starts modulating according to the condensing/evaporating pressure and takes at least the min. opening percentage set by the parameters: par 94 Pressure for max fan speed heat 3.7 bar par 95 Pressure for min fan speed heat 4.2 bar par 96 Pressure for max fan speed cool 17 bar par 97 Pressure for min fan speed cool 13,5 bar if the pressure switch is open the compressor cannot start and an alarm is signalled. A valve closing delay vs. the compressor stop, set by the parameter: par 107 water flow bypass time 0 sec FLOW ALARM MANAGEMENT The water flow alarm is not detected: • with compressor steady • at during valve modulation start-up ( par 100 ) • while modulating ( SUMMER : par 96 / 97 ; WINTER par 94 / 95 ) • in this situation the differential pressure switch could have problems in detecting the flow presence. Therefore the alarm is thus active only if the start-up time has elapsed and if the valve is completely open. The alarm resets automatically, a delay of 30 seconds starts together with the alarm signalling (compressor stop / start time = par 64 , see page 28), after which the alarm is reset and the delay of the flow bypass time (TstartUp) starts again; now the cycle is repeated, as long as the flow check is positive. OPERATION OF THE ON-OFF TYPE WATER VALVES The valve is closed with steady compressor and the flow alarm detection is inhibited. With active compressor, the valve opens immediately and the delay of the water flow alarm bypass time in the exchanger starts. While operating, the alarm detection is always active, as there is no valve modulation. As for the rest, the alarm detection and reset logic is the same as described in the previous paragraph. Also in this case, too, there is a valve closing delay vs. the compressor stop: par 107 Water flow bypass time 0 sec 22 RADIATING PANELS The following is necessary for the management: • expansion PLUG-IN module • radiating panel water temperature probe • external air temperature probe • external temperature radiating compensation enabling The system return water for uses such as FanCoil is used to supply a floor system with radiating panels. A set-point is fixed for the outlet water to the radiating panels. If the water temperature is lower than set point, the valve deviates the water flow returning from the fan coil to the radiating panels. If the water temperature is higher or equal than set point, the valve will close and the panels will work only with their own recirculation water. The water outlet pump to the radiating panels is controlled in parallel with the pump to the exchanger installed on the machine. Thus, it is always active when the chiller is set ON and switches off with a delay that can be set from the machine setting OFF.

Value setting by parameter or by ModBus variable. The valve is managed to obtain water on the panels at the parameter value “192 SetPointTR” independently from the operating mode selected on the chiller. 2. Set point calculated in function of the external air temperature. The electronics determinates two reference set point ( summer / winter ) that are set automatially in base of the operating mode selected on the unit. This configuration is obtained setting “190 EnCompExttR = 1” 3. Summer set point correction in function of the dew temperature value. The system must be interfaced with a ModBus (Ex ElfoControl) net Master, able to communicate the ambient UR and the ambient temperature values thorough the serial. In function of these information, an algorithm inside the board allows to correct the min. summer set point if the dew temperature value calculated is critical. This configuration is obtained setting “191 EnCompRugiada = 1” setpoint 2 - HEATING While the external temperature increases, the heating demand decreases, and thus can be complied even with a lower set-point (increasing the power efficiency). 36,0 35,0 34,0 33,0 32,0 31,0 30,0 29,0 28,0 27,0 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 external temp.

This operation must be enabled by the parameter: 191 Enables the compensation for condensing in cooling mode. 1 num The controller processes the information coming through serial part from Elfo Control (Zone Master): • Ambient temperature • Ambient relative humidity • Ambient Set-point The controller calculates the so-called dew point, according to these values, re-defining the values of • Min. set point in cooling • Max. set point in cooling The dew compensation is automatically deactivated if a communication problem does not allow the values to be transmitted by the Elfo Control to the unit; only the compensation for external temperature remains active in this case. 22.3 RADIATING PANEL WATER ANTIFREEZE SAFETY With unit steady possible freezing in the radiating panels must be prevented. Thus, a radiating water ANTI-FREEZE alarm function is active based on the temperature of the water outlet to the panels, with the same parameters seen for the anti-freeze alarm for the evaporator water described on page 23 When the alarm is activated : • the radiating water pump outputs are automatically activated • the radiating valve sets in opening towards the floor panels (recirculation on panels). When the probe detects a value over the differential for the recovery, • the alarm is AUTOMATICALLY reset • the pump and the valve are piloted again with the standard logic based on the radiating set-point and on the outlet temperature. 22.4 COOLING LIMITING BY DIGITAL INPUT. To prevent from condensing it is possible to control a signal from external digital contact to be connected with the base module, CN1 pins 5 and 11 The regulation logic is the following: Input Closed = Standard operation Input Opened = Valve in full recirculation position on the radiating panel side The logic is active if: • the unit is in cooling mode • par 203 = 1 Enables Cooling Limit With active logic, a signal for “Cooling limit” alarm is enabled with AUTOMATIC reset. par Mnemonic 46 MinStatoValvola 71 MaxRateoRad 118 TempoCorrezione 120 TmaxRicircolo 169 TDeltaChiller 192 SetPointR 205 TempAperturaValv 206 BandaApertura Description Default Min. opening of the radiant modulating valve (0-10V) 20 Variation rateo value of the radiant outlet temp. that impose in closing the on/off valve 2 Radiant Correction time 20 Radiant valve max. time in recirculation position, for the periodical activation on the pump 800 Delta for the control start threshold calculation of the radiant water valve 2 Radiant Set Point (if compensations are disabled) 25 Necessary time to position the VRad from closet to opened 90 It allows to weigh the valve opening time 200 23 DEFROSTING Defrost can occur when: • the unit is working as heat pump • the compressor is active. The cycle starts with: • a pressure test a defined threshold is exceeded • a counting is started o at the counting end the temperature is checked If it is lower than a defined value • defrosting starts. COUNTING CALCULATION The counting, or basic delay time for defrost, is dynamic and is calculated in two ways: according to external temperature or to the enthalpy. EXTERNAL TEMPERATURE ONLY The basic delay time for defrost increases while the external temperature decreases. Indeed, it is supposed that when the external temperature decreases the humidity rate in air decreases, and therefore the need for defrost is lower. BASIC TIME 2700 SEC par 132 1800 SEC par 131 - 10 °C par 134 5 °C par 133 EXTERNAL TEMP. EXTERNAL TEMPERATURE + HUMIDITY or enthalpy defrost The basic delay time is determined according to the air specific humidity calculated through the humidity probe (optional, to be declared present with par 156). The BASIC DELAY TIME for defrost changes depending on the variation of evaporating pressure (ratio). Practically, if the pressure: • decreases quickly the coil is icing and thus the counting must speed up • decreases slowly the counting can slow down • is stable (with low values, too) the counting keeps the values according to the graph above. For example if the pressure in 1 minute falls down of 1 bar ( par130=1) , at every second the time is decreased of 4 seconds ( par 129 ) . Switch to defrost: • keeps the compressor active • the refrigerating circuit direction is reversed through the 4-way valve • The fans are stopped and the low pressure by-pass is active at reversal. • The safety devices remain active • Defrost is performed even if the controller does not require the step anymore. Defrost end: • by temperature or max. time • the compressor is stopped • the compressor can restart in heating after having counted the dropping time or the compressor safety times • the fans are activated at max. speed for 15 sec (par 136) if the external temperature is over 3°C (par 137) Setting the par 135 dropping time at 0, the compressor is not stopped at the of the defrosting but it remains active. FORCING DEFROST FOR LOW PRESSURE In special situations sudden drops in the evaporation pressure can occur (typically while counting the delay time for defrosting, that is with low pressure/external temperature and with high humidity). The defrost forcing prevents such situations. It is active only if the counting of the delay time for defrost has been active for at least 10 minutes. Defrost starts immediately if the pressure drops below 1.4 bar (par 138 defrost forcing pressure), regardless of the temperature value at the coil. If this function is activated for more than 3 times, in the same circuit during one hour of machine operation, this is signalled in the alarm log.
