OUTDOOR SENSOR
„ „
The outdoor sensor is required for the heat pump to operate correctly.
Consult the fitting instructions on the sensor's packaging.
Place the sensor on the coldest part, generally the northern or north-eastern side.
In any case, it must not be exposed to the morning sun.
It must be installed so as to be easily accessible but at least 2,5 m from the floor.
It is essential that it avoid any sources of heat such as flues, the upper parts of doors and windows,
proximity to extraction vents, the underneath of balconies and under-eave areas which would isolate the
sensor from variations in the outdoor air temperature.
- Connect the outdoor sensor to the M and BX4 (B9) terminals on the heat pump control board.
ROOM THERMOSTAT AND / OR REMOTE CONTROL
„ „
The room thermostat (remote control) is optional.
Consult the fitting instructions on the sensor's packaging.
The sensor must be installed in the living room area on a very uncluttered wall, 1,5 m above the floor.
Avoid direct sources of heat (chimney/flue, television, cooking hobs), draughty areas (ventilation, door, etc.).
Air leaks in the seals in the constructions are often translated into cold air blowing through the electrical
conduits. Lag the electrical conduits if there is a cold draught on the back of the IR sensor.
• Installing a room thermostat
- Room thermostat
- Connect the room thermostat to the X86 connector of the heat pump's regulator board using the
connector provided (terminals 1, 2).
- Room thermostat radio
- Connect the wireless room thermostat radio to the connector X60.
• Installing a remote control
- Remote control unit
- Connect the remote control unit to the X86 connector of the heat pump's regulator board using the
connector provided (terminals 1, 2 and 3).
- Remote control unit radio
- Connect the wireless remote control unit radio to the connector X60.
DHW SENSOR
„ „
If the installation is equipped with a DHW tank (with electric back-up):
- Place the domestic hot water sensor in the housing for the cylinder sensors.
- Connect the domestic hot water sensor to terminal BX3 and M.
