The AUTO light goes on.

The FAN SPEED light indicates at which fan speed the appliance is operating.

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.
