Outdoor sensor

The outdoor sensor is required for the heat pump to
operate correctly.
Consult the fitting instructions on the 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 connector X84
(terminals M and B9) on the heat pump control board.
5 .6 Room thermostat
and/or room control unit
The room thermostat (room control unit) is optional.
Consult the fitting instructions on the packaging.
The sensor must be installed in the living room area on
a very uncluttered wall. It must be installed so as to be
easily accessible.
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.
