Note: When the air quality is very good and the appliance operates at a very
low fan speed, the FAN SPEED light for the lowest speed setting does not go
on. In this case only the power-on light and the AUTO light are on.
Note: The built-in air quality sensor measures the air quality and automatically
selects the appropriate speed setting to ensure the best possible air quality in
your room. When the air is clean, the appliance stops running. When the air
quality deteriorates, the appliance starts running at a low fan speed and noise
level so that the energy consumption is minimised.
Night mode
The appliance works in harmony with its surroundings. In auto mode, the
appliance automatically switches to night mode when the room in
which it is operating becomes dark. When the room has been dark for
3 minutes, the lights of the appliance go out, the fan speed and noise
level are reduced and the energy consumption is minimised. If the room
becomes bright again for 5 minutes or longer, the appliance resumes
normal operation.
In night mode, the automatic control is still active. If the air is clean, the
lights and the fan are off. If the air quality deteriorates, the appliance is
activated and the lights and the fan come on again.
Note: The night mode only works when the appliance is operating in the auto
mode.
Fan speed
If you do not use the auto mode, you can select the desired fan speed
yourself.
