Ventilation
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
indoor 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
To provide indoor air quality control, an indoor air quality sensor (DC 0..10 V)
must be connected.
The indoor air quality sensor must be located in the room itself, thus
ensuring that air also circulates around the sensor when the ventilation
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.
