The humidity symbol appears when the "temperature and humidity sensor" is connected. ERV runs at boost speed when humidity higher
than setting value. Under "humidity control" mode, users can set the setting humidity by pressing ▲ and ▼ keys. The setting range
is 45% ~ 90%. And the Dial switch SW4-3 on the PCB should be switched ON to switch from CO
function.

Adjusting the air flow: access the SA (supply) or RA (return) temperature visualisation. The user can set the return air flow
in RA mode, and the supply air flow in SA mode, by pressing the ▲ and ▼ keys. There is a choice of 10 speed levels.
