Summer Cooling (°C)
A special feature of your freeAir 100 is the active summer cooling. In the warm season the
device automatically activates a bypass in order to (mostly at night) cool down rooms with fresh
outside air. The amount of air will be increased, if necessary.
Select your desired temperature for the supply air room.
