The CO2 concentration is an important parameter for indoor air quality. It indicates when used breathing air should be replaced by fresh air. Energy-efficient ventilation measures can be implemented on the basis of the measured CO2 concentration. This can be done by notification, e.g. via a signal tone for manual ventilation, or by connecting the sensor system to a room ventilation system. The room temperature is an essential comfort factor.
By equipping the radiators with maintenance-free thermostats, demand-oriented and thus energy-efficient heating can be implemented.
