Fan start/stop and mixing dampers can be controlled by the air quality function for ventilated premises that have varying occupancy (e.g. a shop or a gym). It is possible to start and stop the fans, compensate the fan speed and, in combination with mixing damper, let in more outdoor air depending on the indoor air quality.

The function can handle one air quality parameter of choice. It is either CO2 or Relative humidity (RH).

note: controlling of RH in the air quality function does not include active humidifiers or dehumidifiers. Active humidity control can be configured as a separate function.
