Air tightness faults in buildings often result in cold
air being blown through the electrical sheathing.
Do not hesitate to seal them off if a cold air draft
comes into the back of the thermostat.
Connections
z
The room thermostat must be connected to the
connector X68 (terminals 1, 2) of the heat pump
controller board. To do this, you can use a 0.5mm²
cable of the two-pair telephone cable type.
If the cable is shielded, the shielding can be
connected to the controller terminal 2. It may under
no circumstances be connected on both sides, i.e.
heat pump regulator side and room unit side.
