Night Cooling
The NIGHT COOLING menu makes it possible to select passive night cooling, provided that the
outdoor temperature on the day before has exceeded the day temperature limit set in the NIGHT
COOLING menu for at least one hour.
During the night cooling period, the compressor cooling is suspended and the room setpoint is
lowered to the temperature set in the NIGHT COOLING menu.
The limit set for the minimum intake temperature is not observed during night cooling, but the sys-
tem may run compressor heating if the room temperature falls below the night cooling setpoint.
No special account is taken of whether the room temperature is above or below the outdoor tem-
perature, i.e. whether a cooling effect from the outdoor air can actually be achieved.
When the night cooling period is over, the system will run as normal again, with compressor heat-
ing and cooling according to the normal setpoint.
