Main menu Heating contractor Air quality
Air quality control can be activated in the standard settings. An air quality sensor then
captures the air quality of the indoor air or the extract air. A drop in air quality results
in an increase in the fan speed or in the selection of a higher fan stage. The fresh
air proportion is increased by a constant opening of the outdoor air and discharge
air damper (if installed). As soon as the selected air quality limit (air quality start) is
exceeded, the speed and the fresh air proportion increase up to the maximum set
speed and the maximum selected fresh air proportion (air quality, maximum).
The values for start and maximum are adjustable. When the actual air quality
< "Air quality, start", the system returns to standard operation (time program or
manual mode). That the system starts when the air quality is poor can be enabled
by means of a parameter.

rate control, only the fresh air proportion is increased if the air quality
control is active.
