General
This accessory includes a freestanding electric control
module, which is used when NIBE is installed in an in-
stallation with passive cooling.
The cooling system is connected to the heat pump col-
lector circuit, through which cooling is supplied from the
collector via the circulation pump and the shunt valve.
When cooling is required (activated from the outdoor
temperature sensor and any room sensor), the shunt
valve and the circulation pump are activated. The shunt
valve regulates so that the cooling sensor reaches the
current set point value corresponding to the outdoor
temperature and the set min. value for the cooling
temperature (to prevent condensation).
If the FLM accessory is installed with PCS 44, the cool-
ing output is reduced.

MOUNTING
Caution
The screw type must be adapted to the surface
on which installation is taking place.
UN
Use all mounting points and install the module upright,
flat against the wall, with no part of the module protrud-
ing beyond the wall.
Leave at least 100 mm of free space around the module
to allow access and make cable routing easier during
installation and servicing.
NOTE
The installation must be carried out in such a
way that IP21 is satisfied.
