deactivated and the supply air fan will be operated at the highest fan stage for 1 min. and then deactivated for safety
reasons. The extract air fan will remain active to heat the heat exchanger. If the exhaust air temperature exceeds the
heat exchanger frost protection temperature, the normal operating mode will be activated.

Allocation to Description
function
If contact is open, the unit will switch to standby mode (stage 0), the protec-
tion functions (e.g. heat exchanger frost protection) will remain active. If the
contact is closed, the unit will switch to ventilation mode.
If a switch is connected, the unit will operate at the highest fan stage (Boost)
for 15 minutes with a closed contact (max. 2 sec.). If the contact is closed
for more than 2 sec., the unit will operate at the highest fan stage. If the con-
tact is open, the previously activated operating mode will be used.
External
If a switch is connected, the unit will operate at the highest fan stage (Boost)
contact
for 30 minutes with a closed contact (max. 2 sec.). If the contact is closed
for more than 2 sec., the unit will operate at the highest fan stage. If the con-
tact is open, the previously activated operating mode will be used.
If the contact is closed, the bypass will open. "External contact" will be sig-
nalled on the display. If the contact is open, the bypass will close again.
Unit operated according to passive house criteria.
Unit configu-
ration
Unit operated according to DIBt criteria.
Relay output when unit is on.
Error output
(composite
error)
Relay output in case of unit errors (defective fans, frost protection heat
exchanger, filter change etc.).
