Installing the room unit

Choosing a location
Since the temperature measurement sensor is inside the unit, you must install the thermostat flush-mounting box: - in zone 1 (main room) only, - on an accessible wall at a height of 1.50 m, - away from heat sources (fireplaces, sunlight) and draughts (windows, doors). 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.

Mounting

Mounting the room unit
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.

Installing the sensors

Feed (zone 1) and return (zone 2) sensor
The water temperature sensors are wall-mounted. They are used to measure the surface temperature of pipes. They can be used in a measurement range of 30C to +150C, and are fitted as standard with a 10 k NTC measuring element. The sensors have a clamp so that they can be attached to pipes up to 1" 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.
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. Connect the unit before closing the cover.

Outdoor sensor

The outdoor sensor must be attached to a vertical wall with screws and plugs.
The recommended position is on a wall facing north or north-west, away from unwanted heat sources (fireplace, air vents, thermal bridges, etc.).

Connection

Determining the type of installation
Application 1: 1 underfloor hot water zone, 1 radiator zone (with thermostatically controlled valves)

Zone 1 can be fitted with radiators that have thermostatically controlled valves operating as limiters. -7-
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 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.
do not mistake for the clock input (on some boiler models)
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.

remove the shunt

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.

- Restore the settings required for normal use, - Close the cover of the technical unit.
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 units 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.

Corresponds to the maximum time for the valve to open or close.
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.
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.
Default setting: C09=0 and the time set is 120 seconds.
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 Changes allowed (from 0 to 20 minutes/C) Upon activation, the time is set to 5 min./C.
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 17C. The Comfort temperature setting is 20C. C10 is set to 30 min/C. For room temperature to have reached 20C by the time Comfort mode is programmed to come on, heating will need to begin 1.5 hours in advance: Ta = (20C - 17C) x 30 min./C = 1:30.
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.
Upon activation, the time is set to 5 min./C.
Menu C12: Control differential for zone 2
Changes not allowed Setting the control differential for zone 2 Changes allowed (from 0.5C to 10C) Upon activation, the temperature is set to 3C.
Default setting: C10=0 and anticipation time is set to 30 minutes/C.
