Adjusting the air quality sensor sensitivity
People with certain health problems (e.g. allergies or asthma) have a
greater need for healthy air. For this reason, the air purifier allows you to
adjust the sensitivity of the air quality sensor. When it is set to a higher
sensitivity level, the appliance already starts cleaning the air at lower
pollution levels to make the air even cleaner.
There are 3 sensitivity levels:
- extra sensitive
- sensitive
- standard
The air quality sensor is set to standard sensitivity. You can adjust the
sensitivity of the air quality sensor in the following way:
1
If the appliance is already plugged in, unplug the appliance and wait for
a few minutes.
2
Press and hold the TIMER button and simultaneously put the mains
plug in the wall socket.
• The appliance beeps twice and one of the HOUR lights flashes to
show the current sensitivity level of the air quality sensor.
