Indoor air quality control
The indoor air quality controller calculates a positioning signal based on the
current setpoint (in accordance with the ventilation level) and the current in-
door air quality.
From this, the linear step selector derives the ventilation stage presently re-
quired.
The ppm level of indoor air quality is displayed on the central apartment unit.
Indoor air quality at 0 V/10 V
Connect an indoor air quality sensor (DC 0..10 V) to provide indoor air quality
control sensor.
The indoor air quality sensor must be located in the room itself, thus
ensuring that air also circulates around the sensor when the ventila-
tion system is off. Do not install the sensor in the extract air duct.
The ppm level for 0 V and 10 V (0..2000 ppm) can be set.

P-band Xp indoor air quality
A P-controller is used to ensures that the indoor air quality is maintained at the
required setpoint. The controller's P-band (0..2000 ppm) can be set here.
Within this range, all available stages are switched on and off.
