Air quality sensors (optional)

CO2 sensor: Measures the carbon dioxide content of the air. Setting range of CO2 limit value 500 to 2000 ppm

VOC sensor (odours): Measures all oxidable organic substances in the air (CO, methane CH4 etc.). Setting range of VOC limit value 500 to 2000 ppm

If the status is Optimal, the air quality is within the set range. If Critical is displayed, the upper limit value has been exceeded. The ventilation unit generates a message.
