SYSTEM OVERVIEW
CS2-Connect CO
2
sensor (incl. humidity/temperature sensor)
Figure 4: CS2-Connect CO
2
sensor
The CS2-Connect CO
2
sensor (in the following text "CO
2
sensor") is a sensor for extended back-
ground monitoring of the CO
2
concentration in the indoor air in the respective ventilation zone. It
also has a humidity/temperature sensor for monitoring the humidity indoors as well as the indoor
temperature.
The CO
2
sensor operates according to the NDIR (non-dispersive, infrared) measuring principle
by using an infrared light tuned to the wavelength of CO
2
. The attenuation of the infra-red light is
detected by the sensor and converted into a processable output signal.
It detects the CO
2
concentration in the ambient air within a range of 400 – 10,000 ppm. The higher
the CO
2
content of the air, the worse the room air quality.
It transmits the CO
2
values determined to the controller by radio (RF868MHz network) or RS485
data cable. If the measured
CO
2
content of the indoor air exceeds the limit defined via the app
(factory setting 1,500 ppm), all ventilation devices assigned to the ventilation zone are switched to
ventilation operating mode, level 3.
