Elektrical connection
The electrical connection must be implemented according to VDE 0100. For installation and
maintenance work, disconnection from the mains on all poles with at least 3 mm contact opening width
must be undertaken. The mains disconnection is to be secured against reconnection!

Connection of AirUnit compact controller pro
5.1 Connection AirUnit(s) – controller
The connection of the devices occurs arranged in pairs at the plug connectors. In paired operation one device of a
device pair operates in feed mode, the second assigned device in exhaust air mode The air flow direction of both
devices is alternated at intervals.
Maximum 4
AirUnit ventilation units
can be operated with the
AirUnit compact controller pro
. Therefore
maximum 2
AirUnit ventilation units
are to be connected in parallel on plug-in connector
Fan 1
and maximum 2
AirUnit ventilation units
on plug-in connector
Fan 2
.
Those
AirUnit
ventilation units
, which are connected on the plug-in connector
Fan 1
serve as exhaust fan regar-
ding to the function “summer mode”.
AirUnit ventilation units
which are connected to plug-in connector
Fan 2
become supply fan in “summer mode”. If several units are used, cross ventilation can be provided, e.g. to convey
cool outside air into the building during the night hours in summer.
By using a single device, the AirUnit ventilation unit can be used as supply- or exhaust fan in “summer mode”.
The connection of the AirUnits to the connection line of the controller is implemented via a plug connector
contained within the scope of delivery of the ventilation units, as depicted previously. Please observe the polarity
feed / exhaust devices (see Fig. above)!
