0-2000 ppm
The CO
2
-sensor is supplied as a separate accessory.
When installed in the duct position the sensor in the ex-
tract air duct as close to the air outlet as possible.
When installed in a room position the sensor where the
air quality is representative, for example, on an open wall
at a height of 1.5–3 metres. Connect the CO
2
-sensor to the
same input as the pressure sensor GP6; see the table for
CO
2
compensation. If the mixing damper is CO
2
control-
led connect the CO
2
sensor to the Z terminal block.
NOTE!
These cannot be connected at the same time!
