HOMCOM 823-033V80 Assembly & Instruction Manual page 25

The air quality indicator will be lit when switching on the product.
This product will start on auto mode.
If the humidity of the room is high, condensation may form on the air quality sensor.
If this happens, the indicator will display poor air quality, even if the air quality is
good. That means the auto mode may change the fan to the high wind speed. To fix
this issue, clean the air quality sensor. It is suggested to use the manual speed
settings if the problem occurs frequently.
Manual adjustment of wind speed
Under the manual mode, you can use the fan speed button to choose your preferred
settings. The settings include gear one, two, three and four.
When in auto, silent or night mode, press the fan speed button to switch to manual.
Press once to change to the next setting. The relevant colour will be displayed on
the indicator.
