2.3.1.2 Functional principle of CO
2
/ VOC sensor
The CO
2
sensor module and the VOC sensor module are each combined with a humidity/temperature
sensor.
The CO
2
sensor module and the VOC sensor module both offer the option to evaluate relative air humidity as well as the
air quality for controlling the ventilation unit. The VOC sensor module detects volatile organic compounds (VOC) and the
CO
2
sensor module, as NDIR sensor (nondispersive infrared sensor), detects carbon dioxide (CO
2
). Volatile organic
compounds correlate really well with the CO
2
concentration in living spaces. In the evaluation of the current sensor signal
for the setpoint selection, the fans are regulated in accordance with the characteristic curve in diagram 2.
Diagram 2: Factory setting characteristic curve for Automatic operating mode with CO
2
/ VOC control
The CO
2
and VOC sensor modules combined with a humidity/temperature sensor can be deactivated
separately if needed, in accordance with the humidity or air quality control. If both sensor modules are
configured as active, the control characteristic of the sensor module is designed with the greater sensor
signal.
The required hardware settings on the control system are only allowed to be made by qualified personnel!
Maintenance by the user
If the maintenance work is not carried out regularly, this will affect the functionality of the ventilation unit
in the long run!
The maintenance of the ventilation unit for the user is limited to changing the filters periodically and to cleaning the unit on
the surface, if needed. Check the filters if this is indicated by the filter replacement LED.
Replace the filters at least every six months. This ensures a pleasant and healthy air quality, and the unit
will be protected against contamination.
Cleaning the surface of the unit, and specifically the control panel, is possible using a damp cloth and a
mild soap solution. Never just wipe it dry!
Unsuitable cleaning agents are:
•
Alcohol (> 5%)
•
Acetone
