The clean fan filter reminder function counts the fan operating hours and displays
message “FIL” to remind the user to clean the fan filter as soon as the threshold
is reached. This does not impact controller operations, which continues to run
normally.
The service interval can be set via parameter P62.
The clean filter reminder is reset when the operating mode is manually set to
Protection respectively .
In Auto Timer mode, default fan mode is automatic. The fan mode can be changed
to manual by pushing the “FAN” button. The fan returns to the automatic default
mode after each switchover from Comfort to Economy and vice-versa.
