The device is a combined sensor for CO2, temperature and humidity measurement (relative humidity).It is used to monitor the air quality in meeting rooms, offices, schools/kindergartens , passive or low-energy houses and living areas without controlled ventilation.
The CO2 content of the air is a verifiable indicator of the ambient air quality. The higher the CO2 content, the worse the ambient air is.
Threshold adjustment range: 500–2550 ppm. Object ""Physical value": 0-9999 ppm. There are 3 independent measured value thresholds for CO2 and relative humidity and a threshold for the temperature value. An action is carried out if the thresholds are not reached or if they are exceeded: Send priority. Switching, value. Each threshold has a locking object.
