Acknowledging a filter change
After 180 days (approx. 6 months), the required filter change is indicated by alternate flashing of
the red and green LED.
Once the filter has been changed, this must be confirmed on the controller.
Requirements:
•
The red and green LEDs are flashing alternately.
► Change the filters on the ventilation units (see the
operating instructions for your particular ventilation
unit).
To do this, pause the ventilation unit.
►
Move both rocker switches to the same position
(OFF or ventilation level 3).
►
Simultaneously switch both rocker switches back
and forth twice from their current position.
All switching operations must be carried out
within around 2 seconds (switch back and
forth quickly).
Both LEDs go out.
The LED to indicate the current operating mode
lights up solid for 10 seconds.
The filter change interval is reset to 180 days.
►
Select the ventilation level at which the ventilation
unit is to operate.
