Without electric heaters
000 - Unit has no electric heaters, the outdoor
air is heated only with a counterow heat
exchanger.
Electric preheater (HE1)
The preheater protects against too low outdoor
air temperature entering the heat exchanger.
E01 - Low power
E02 - High power
Electric reheater (HE2)
The reheater heats the fresh air to the desired
temperature before entering the room.
0E1 - Low power
0E2 - High power
Electric preheater (HE1) and reheater (HE2)
The preheater protects against too low outdoor
air temperature entering the heat exchanger.
The reheater heats the fresh air to the desired
temperature before entering the room.
EE1 - Low power
EE2 - High power
