12 Filter maintenance
The ventilation unit has a runtime-controlled filter monitoring function with visual display.
It monitors the time since the last air filter change. If the last air filter change was more
than one year ago, the filter change display is activated and a pending air filter change is
signalled by LED 1, which lights up constantly (see Fig. 12 on page 23).
No tools are needed to change the air filters.
NOTICE
► Follow the instructions for changing the air filters in section 6.3 on page 22.
