2 .12 Outdoor sensor
The Outdoor sensor is required for the correct operation
of the heat pump
Consult the assembly instructions on the packaging of
the sensor.
Place the sensor on the front panel that is the worst
exposed, in general the North or North west front panel.
Under no circumstances must it be exposed to the sun
in the morning
It is to be installed so that it is easily accessible but at
least 2.5 m from the ground.
Avoid sources of heat such as chimneys, the tops of
doors or windows, nearby extraction ducts, underneath
balconies and porches, that would insulate the sensor
from the variations in the temperature of the air outdoors.

Connect the outdoor probe to terminals
M
and
B9
on the regulation board of the PAC
(
2 .13 Ambient sensor
and/or central ambient unit (radio)
The ambient sensor (or the central ambient unit) is
optional
Consult the assembly instructions on the packaging of
the sensor.
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 sources of direct heat (chimney, television,
cooker, sunlight) and areas exposed to draughts
(ventilation, doors). Draughts due to the building usually
cause cold air to enter via the electrical ducts. Seal the
electrical ducts if there is a cold draught at the back of
the ambient sensor.
