The appliance automatically starts operating in the auto mode.
To switch off the appliance, press and hold the on/off button again until the
power-on light goes out and unplug the appliance.
Note: When the humidity level in the room is very high, it is possible that
condensation develops on the air quality sensor. As a result, the AIR QUALITY
lights on the control panel may indicate that the air quality is bad even though
the air quality is good. In this case, the auto mode causes the appliance to
run at high fan speed. You can solve this by cleaning the air quality sensor. If
condensation develops frequently during periods of high humidity, we advise
you to use one of the manual speed settings.
Auto mode
When the appliance is switched on, the built-in air quality sensor
automatically measures the ambient air quality. When the auto mode is
activated, the appliance selects the most appropriate fan speed for the
measured air quality.
Note: When you use the auto mode, you can also use the timer function (see
section ‘Timer function in this chapter). In this case, the AUTO light, one of the
FAN SPEED lights, the TIMER light and one of the HOUR lights are on.
