IMPORTANT: Do not install the thermostat on a wall in contact with the outdoors or with an unheated room (e.g. garage, etc.). The sleeve output in the flush-mounting box must be plugged (with mastic) in order to avoid unwanted air movements that would cause the sensor reading to be inaccurate.

They are used to measure the surface temperature of pipes.. They can be used in a measurement range of 30°C to +150°C, and are fitted as standard with a 10 kΩ NTC measuring element. Switch off the mains power supply (general circuit breaker) before proceeding. To attach the unit to the wall, you must separate it from its base. To do this, unscrew the lock screw as shown opposite. 2 1 Once separated from the unit, the base can be connected to the technical unit via the bus, then attached to the flush-mounting box (distance between centres: 60 mm). Screw the unit closed. Mounting the technical unit The technical unit must be installed next to the boiler. Remove the cover and attach the unit using screws and plugs. The sensors have a clamp so that they can be attached to pipes up to 1½" in diameter. The feed sensor (zone 1) must be installed after the mixer valve, between the circulator (~50 cm) and the connected equipment (underfloor heating or radiators). The return sensor (zone 2) must be installed on the return of the direct radiator network. To ensure that the temperature is measured correctly, apply the thermal paste from the syringe between the sensor and the pipe. Outdoor sensor The outdoor sensor must be attached to a vertical wall with screws and plugs. Connect the unit before closing the cover. The recommended position is on a wall facing north or north-west, away from unwanted heat sources (fireplace, air vents, thermal bridges, etc.). -4- -5- Connection Determining the type of installation Application 1: 1 underfloor hot water zone, 1 radiator zone (with thermostatically controlled valves) Application 3: 1 radiator zone (without thermostatically controlled valves), 1 radiator zone (with thermostatically controlled valves) Outdoor sensor Outdoor sensor S S Boiler thermostat input control Zone 2 Room unit in zone 1 Circulator zone 2 Boiler thermostat input control Zone 2 Room unit in zone 1 Circulator zone 2 Mixer valve Mixer valve Zone 1 M Zone 1 M S Feed sensor zone 1 Circulator zone 1 Return sensor zone 2 S S Return sensor zone 2 Application 2: 1 underfloor hot water zone Feed sensor zone 1 Circulator zone 1 S Application 4: 1 radiator zone (without thermostatically controlled valves) Outdoor sensor Outdoor sensor S S Boiler thermostat input control Boiler thermostat input control Mixer valve Mixer valve M M S Circulator zone 1 S Feed sensor zone 1 IMPORTANT: If zone 2 is not used, switch it to Economy mode (with a setting of 10°C). -6- Circulator zone 1 Feed sensor zone 1 Zone 1 can be fitted with radiators that have thermostatically controlled valves operating as limiters. -7- Connection The wiring for the boiler thermostat input control is optional. It must be connected if you wish to authorise reductions when the DELTA 200 is not being used for heating. The diagrams provided are simplified for greater clarity. Protections and other accessories required by standards are not illustrated. - The connection must comply with UTE standard NF C15-100 and good practice. - Nearby units or those that are connected must not generate excessive interference (directive 2004/108/EEC). • The contact sensor cable is 2.5 m long. • The outdoor sensor can be connected using Ro2V cable (1.5 mm2). • Sensor cables must never be longer than 50 m. • Use an optional rate 3-way mixer valve, equipped with a 24 V or 230 V servomotor. Duration of travel: 60 sec. to 240 sec. Room unit To connect it, remove the shunt (electric wires to be wire) connecting the two thermostat input connected to the thermostat terminals. If the boiler has a clock input, do not mistake it for the thermostat input. Testing the installation Boiler thermostat input Zone 2 circulator Zone 1 circulator Mixer valve M Before closing the cover of the technical unit: - Switch the installation on, - Check that the green LED comes on (dialogue between the technical unit and the room unit), - Use a temperature setting that is high enough to activate the heating, - The red LEDs indicate the status of the relay outputs: Dialogue Valve opening Valve closing Green LED Zone 1 Valve Network Feed Sensor Zone 2 Outdoor Direct sensor Network Return Sensor NTC sensors 10,000 Ohms at 25°C To room unit Pwr sup.

IMPORTANT : - Before connecting the return sensor for network 2, remove the resistor wired to terminals 3 and 4. - To prevent any confusion when connecting the bus, it is advisable to use a cable of a completely different colour from that used for the unit’s power supply (take care to align the poles properly). - Any junctions or terminal block connections must be made outside the unit. - The underfloor heating system must have a safety device that automatically cuts off the supply of heat to the underfloor heating system when it reaches the limits set by DTU standard 65.8. This underfloor heating security thermostat must be connected in series to the zone 1 circulator. - In this wiring example, the mixer valve is supplied with 230 V power. Some valves may be supplied with 24 V power. If this is the case, you must modify the wiring. -8- remove the shunt do not mistake for the clock input (on some boiler models) -9- Circulator 2 Circulator 1 Activation Turn the knob to Menu C03: Setting the minimum water temperature for network 1 . General principle: In each menu, press the and press to go to the next menu. or button to modify, This is the minimum temperature provided for a heating request from the network. Changes not allowed Menu C01: Access to program and setting changes To modify settings, press the buttons in the following sequence: times, 3 times, 5 times. 5 Modification of installer settings Programming limitation Allowed No Access to the installer and programming limitation settings Not allowed No Not allowed • Programs cannot be modified • The frost protection setting cannot be changed • For each zone, the temperature settings are from 5°C to the Comfort setting Authorisation to modify the minimum temperature for network 1 Default setting: C03=0 and the temperature set to 20°C. OK Menu C04 : Réglage de la température d’eau maximum du réseau 1 Changes not allowed Authorisation to modify the maximum temperature of network 1 Default setting: C01=0 Menu C02: Outdoor temperature for no heating Above this temperature, the circulators are off. The boiler thermostat input control is off and the valve is forced to close. Changes not allowed Authorisation to modify the outdoor temperature for no heating Changes allowed (from 15°C to 25°C) Upon activation, the temperature is set to 20°C Default setting: C02=0 and the temperature set to 20°C. Changes allowed (from 20°C to 60°C) Upon activation, the temperature is set to 20°C Changes allowed (from network 1 minimum T° + 1°C to 90°C) Upon activation, the temperature is set to 50°C (to match underfloor heating requirements). IMPORTANT: If you are using underfloor heating, the temperature must not exceed 50°C. When you increase the maximum temperature of network 1 from 50 to 51°C, network 1 acquires the status of a radiator network: - zone 1 automatically goes into Comfort mode from 6am to 11pm for each day of the week, - the slope of zone 1 is initialised at 2. When you decrease the maximum temperature of network 1 from 51 to 50°C, network 1 acquires the status of an underfloor heating network: - zone 1 automatically goes into continuous Comfort mode for each day of the week, - the slope of zone 1 is initialised at 0.8. Default setting: C04=0 and the temperature set to 50°C. OK OK - 10 - - 11 - Activation Menu C05: Setting the minimum water temperature for network 2 Zone 2 does not have a room sensor. Adjustments are made using the thermostatically controlled valves. The setting displayed on DELTA 200 is merely theoretical. Menu C07: Setting the slope of zone 1 (see pg. 14) Changes not allowed Authorisation to change the slope of network 1 (zone 1) Changes allowed (from 0 to 4 in increments of 0.1) Upon activation, the slope is set to 0.8. Default setting: C07=0 and the slope is set to 0.8. Changes not allowed Authorisation to modify the minimum temperature for network 2 Changes allowed (from 20°C to 60°C) Upon activation, the temperature is set to 20°C Changes not allowed Authorisation to change the slope of network 1 (zone 1) Changes allowed (from 0 to 4 in increments of 0.1) Upon activation, the slope is set to 0.8. Default setting: C05=0 and the temperature set to 20°C. Example 1: Setting network 1 for underfloor heating OK Menu C06: Setting the maximum water temperature for network 2 To determine the correct slope for your installation, on the corresponding axes, note down the maximum feed temperature for network 1 (set in menu C04, e.g. 45°C) and the minimum outdoor base temperature (e.g. -6°C). In this example, the correct slope is 0.9. IMPORTANT: In a few days (if the programming authorises enough comfort periods), DELTA 200 will automatically adapt the slope to the installation settings: this is self-adaptation. Changes not allowed Authorisation to modify the maximum temperature of network 2 Changes allowed (from network 2 minimum T° + 1°C to 90°C) Upon activation, the temperature is set to 80°C. Default setting: C06=0 and the temperature set to 80°C. Example 2: Setting network 1 for radiators On the corresponding axes, note down the maximum feed temperature for network 1 (set in menu C04, e.g. 75°C) and the minimum outdoor base temperature (e.g. -6°C). In this example, the correct slope is 2.

On the corresponding axes, note down the maximum return temperature for network 2 and the minimum outdoor base temperature (e.g. -6°C). In this example, the correct slope is 1. Manual setting: Set the temperature to 20°C on the DELTA 200 and set the thermostatically controlled valves to maximum. For outdoor temperatures of around 10°C, you must obtain 20°C in the room measured. Use a higher slope if the temperature is lower. Use a lower slope if the temperature is higher. Return the thermostatically controlled valves to the desired setting.

Changes not allowed Setting the valve operating time (zone 1) Changes allowed (from 1 to 240 seconds) Upon activation, the time is set to 120 seconds. Default setting: C09=0 and the time set is 120 seconds. OK IMPORTANT: To determine the valve operating time, refer to the valve documentation. Menu C10: Anticipation value of zone 1 Anticipation is the time it takes to reach the desired temperature at the time specified in the program, namely: Tanticipation = (Zone 1 setting - Zone 1 T° as measured) x Setting C10. It keeps the temperature from rising too quickly, which would consume too much energy. Example: You are in economy mode and the room temperature is 17°C. The Comfort temperature setting is 20°C. C10 is set to 30 min/°C. For room temperature to have reached 20°C by the time Comfort mode is programmed to come on, heating will need to begin 1.5 hours in advance: Ta = (20°C - 17°C) x 30 min./°C = 1:30. Tip: Initially, use the default setting (30 min/°C). - If the desired temperature is reached too quickly, set a higher value (e.g. 45 min./°C). - If the desired temperature is not reached quickly enough, set a lower value (e.g. 20 min./°C). IMPORTANT : If you do not require anticipation, set C10 to 0. Menu C11: Setting the temperature increase time for zone 2 This is the period during which overpower is used in zone 2 to increase the temperature. The following formula is used when switching from Economy to Comfort mode: Toverpower = setting C11 x (zone 2 setting - outdoor T°) The following formula is used when switching from Shutdown or Frost Protection to Economy or Comfort mode: Tsoverpower = 2 x setting C11 x (zone 2 setting - outdoor T°) Changes not allowed Setting the overpower time for zone 2 Upon activation, the time is set to 5 min./°C. OK Menu C12: Control differential for zone 2 Changes not allowed Setting the anticipation time for zone 1 Changes allowed (from 0 to 120 minutes/°C in increments of 5) Upon activation, the time is set to 30 min./°C. Default setting: C10=0 and anticipation time is set to 30 minutes/°C. Changes allowed (from 0 to 20 minutes/°C) Upon activation, the time is set to 5 min./°C. Changes not allowed Setting the control differential for zone 2 Changes allowed (from 0.5°C to 10°C) Upon activation, the temperature is set to 3°C. Default setting: C12=0 and the differential is set to 3°C. OK OK - 16 - - 17 - Default setting: C15=0.
