2 1 1 Installation of the control box

Install at a place that can withstand the weight of the
control box and install positively so that the box will not
topple or fall.

2 1 2 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 M and B9 terminals
on the heat pump control board (see
Installation and operating manual "1395 - EN"

2 1 3 Room thermostat (option)

Consult the fitting instructions on the 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.
- Connect the sensor to one of the CL+ and CL-
terminals (see
figure
8).

2 1 4 Room control unit (option)

Consult the fitting instructions on the packaging.
The room control unit must be installed in the living area
to approximately 1,5 m above the ground, a wall well
clear.
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.
- Connect the room control unit : terminals CL+ on (1),
CL- on (2) and G+ on (3)
