VENTILATION RECOVERY
The installation can be supplemented with the exhaust
air module NIBE FLM to provide ventilation recovery.
• Pipes and other cold surfaces must be insulated with
diffusion-proof material to prevent condensation.
• The brine system must be supplied with a pressure
expansion vessel. If there is a level vessel this should
be replaced.
P
FREE COOLING
The accessory PCS 44 allows the connection of passive
cooling, for example with fan coils. The cooling system
is connected to the heat pump brine circuit, whereby
cooling is supplied from the collector via a circulation
pump and shunt valve.
• Pipes and other cold surfaces must be insulated with
diffusion-proof material to prevent condensation.
• Where the cooling demand is high, fan convectors
with drip trays and drain connection are needed.
• The brine system must be supplied with a pressure
expansion vessel. If there is a level vessel this should
be replaced.

TWO OR MORE CLIMATE SYSTEMS
In buildings with several climate systems that require
different supply temperatures, the accessory
ECS 40/ECS 41 can be connected. A shunt valve then
lowers the temperature to the underfloor heating sys-
tem, for example.

POOL
With the POOL 40 accessory, you can heat the pool
with your heat pump.
During pool heating, the heating medium circulates
between the F1245 and the pool exchanger using the
heat pump's internal circulation pump.
