In automatic operation the fan step is controlled automatically based on the
difference between the actual and the reference humidity value. Automatic
operation is active only if humidification is on. If humidification is inactive the
“A” setting corresponds to fan step “1”.
The following recirculation cycles per hour are recommended for air puri-
fication:
– Normal load: 1 – 2
– heavily polluted air (e.g. pollen, smoke, etc.): 3 – 4
