How It Works / Basic Function
The Air Control Signal air quality
sensor described below meas-
ures the concentration of car-
bon dioxide (CO ) in room air by
2
means of an optical two-chan-
nel measurement system.
The CO air quality sensor uses
2
an LED "traffic light" display
(green, amber, red) to indicate
when the quality of room air
rises above or falls below in-
ternally selected threshold
values. On red, a short acoustic
warning signal additionally
warns every 5 minutes.

The Air Control Signal air quality
sensor also provides a floating
switching output for connecting
an automatic ventilation system.
Ventilation is switched 'ON' in
the amber range and only
switches 'OFF' again when the
green LED shows.
However, the Air Control Signal
air quality sensor is not intend-
ed for use as a measuring
device or as part of a gas war-
ning or other safety system. The
sensor is designed for operation
in dry rooms at a temperature of
5°C to +40°C.
