Boost ventilation
mode/reset filter
running time button Function button for boost ventilation mode:
Pressing this button activates boost ventilation for 15 minutes with an air volume flow
corresponding to the rotary knob being turned all the way to the right. At the end of the 15-
minute boost ventilation time, the unit reverts to the previous air volume in the currently
active mode. You can cancel boost ventilation mode at any time by pressing this button
again for > 3 s.
Function button for reset filter running time:
To ensure cyclic filter inspection, the control has an integrated operating hours counter
with a fixed running time of 180 d. The boost ventilation mode/reset filter running time
button allows you to reset the filter running time. To restart the filter running time, press
and hold this button for > 3 s.
If the filter running time is reset before the end of 180 d by pressing this button for > 3 s,
the LED fan symbol will flash rapidly four times in succession to confirm the reset operation.
No reset command can be issued while boost ventilation mode is active.

Tab. 3: Functions assigned to LED signals
External control signal, 0–10 V
The ventilation unit can be operated with an external 0–10 V control signal. When a 0–10 V analogue signal is applied,
it is interpreted as a control signal for the fan speed. The current position of the rotary knob on the scale marks the
point at which the external control voltage becomes effective.
To make use of the entire external 0–10 V control range, control range, the rotary knob must be in
position 3
rd
scaling segment.
Boost ventilation mode with external boost ventilation button
Boost ventilation buttons are usually installed in rooms from which air is extracted, such as bathrooms, toilets or
kitchens. In this way, maximum ventilation can be activated locally within these rooms for a brief period to enable rapid
extraction of high humidity and odours. When this control module is activated, the functional features and displays
described for boost ventilation mode apply. Boost ventilation mode is restarted each time it is activated and interrupts
the currently set air volume flow. Afterwards, the unit reverts to the previously active working condition.
