The fan and heat pump runs until the additional
temperature T5 placed in the room environment is
below a certain level. The water temperature can
only reach the maximum temperature allowed in
the tank D33 (T HP max). The cooling function ac-
tivates a three-way damper, which directs the cold
exhaust air to a room with cooling requirements.
The two functions operate the damper in opposite
directions.
Cooling 1 (2). If the T5 is higher than B10 T
Cooling, the extra relay that operates the damper
(GP1) switches ON (OFF).
If the T5 is lower than B10 (T Cooling), the extra
relay that operate the damper (GP1) switches OFF
(ON).
