Switching off the ventilation
In this mode, the reversible fans on the ventilation device are switched off. The ventilation units
do not work and there is no exchange of air. In this state, close the inner cover. Select "Off" if your
ventilation unit is to remain switched off for a prolonged period, e.g. to clean the ventilation device
or when the inner cover is closed.
OFF mode is set by changing the switch positions.
Switching off the ventilation unit
Switching the ventilation unit back on
►
Select any of the ventilation levels 1 - 3.
All of the ventilation units connected to the control-
ler restart at the selected ventilation level.
► Switch both rocker switches off.
All of the ventilation units connected to the control-
ler are switched off.
In individu
al cases, after the ventilation unit has been switched off for an hour, it restarts in heat
recovery operating mode at ventilation level 1. This is not an error, but rather the flat version of the
Pure controller.
Complete switch-off of the ventilation unit is only possible with the standard version of the Pure
controller.
