protection, the unit cools down the room in recirculation opera-
tion. If the temperatures also permit fresh air cooling, the unit
automatically switches to night cooling (NCS) to save energy.
NCS ■Night cooling:
If the room temperature exceeds the set value for night cooling
and the current fresh air temperature permits it, the unit blows
cool fresh air into the room and extracts warmer room air.
