set setpoint sliding select menu window:
8. Air quality function setting
To set the air quality (AQ) function select menu window:
"On" – AQ function on.
"Off" – function off.
After function is activated, the type of sensor, which is connected to the unit, is selected:
"VOC1" (Volatile Organic Compound) – air quality sensor having signal-dependent linear relationship, the maxi-
mum value of output signal corresponds to the highest air quality.
"VOC2" – air quality sensor having inverse relationship, the maximum value of output signal corresponds to
lowest air quality.
RH – relative humidity sensor.
CO
– carbon dioxide sensor.

Depending on the sensor type, the value of AQ function is set, according to it the intensity of the unit is regulated.
If actual air quality value varies from the setpoint then ventilation intensity will increase otherwise – decrease.
For instance, if the humidity maintaining system is designed in the device, and there is additional relative
humidity (RH) sensor, then by setting 65 % in the air quality window, and by regulating the intensity of ventilation
automatically, humidity of 65 % will be maintained, i.e. if humidity increases, ventilation intensity will be increased
as well, and if humidity reduces, the device will switch back to the previous mode.
This function is not provided in the units with AC fans.
