15.4. VOC/eCO2 control
The room air quality is measured via VOC and eCO2 sensors, and the air volume flow is controlled in a demand-oriented fashion. In
the automatic mode, the ventilation unit regulates the air volume flow as a function of the air quality (VOC) or the eCO2 values on a
needs-based basis. The greater the value, the larger the volume flow.
Acceptable room air should not exceed a CO2 value of approx. 1000 ppm and have air quality class 1 to 2.

15.5. Outdoor air quality control
If the ventilation unit has been configured by the factory with an (optional) VOC/eCO2 sensor in the outdoor air, the function can be
activated via the APP. If the outdoor air quality (VOC value) is less than class 4 for a certain time, the ventilation unit changes to the
Standby mode. After approx. one hour in standby operation, the ventilation unit is restarted automatically.
