Operation
3.1 General information
The heat recovery and ventilation operating modes can be changed by moving the left-hand
rocker switch back and forth 2 times. The pause operating mode is switched on or off by moving
the right-hand rocker switch back and forth 2 times. The ventilation unit can also be switched off
completely (standard version only).
There are three ventilation levels for the ventilation units which define the rotational speed of the
fans and therefore the intensity of the units' air flow.
The ventilation levels are adjusted by changing the switch positions

If the LED is flashing, this indicates a state that must be actively resolved by the user or controlled
by the sensor technology.
