Remote control
* If the control component does not provide a spare potential contact, the contact must be relayed to create equivalent wiring.
In all cases, please refer to the instruction manuals for the external components (load limiting device, power meters) to create the wiring.
Figure 38 - Connections to the heat pump regulator (accessories and options)
External faults the heat pump
Any component of carryforward of information
(thermostat, pressure switch, etc.) may signal an
external problem and stop the heat pump.
E.g.: A thermostat on the heating floor will stop the
heat pump if the temperature in the floor is too high
- Connect the safety component to input EX6.
230 V on input EX6 = stoppage of heat pump (the
system displays Error 369).
2.10 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 2.5m from the floor.

External component contact*
(faults, load shedder, power meter)
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 outside air
temperature.
- Connect the outdoor sensor to the M and B9
terminals on the heat pump control board (fig. 38,
p. 29).
2.11 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, 1.5m above the floor.
Avoid direct s ources of heat (chimney/flue,
t e l e v i s i o n , c o o k i n g h o b s ) , d r a u g h t y a r e a s
(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.
