signal with a connected
CO

/humidity sensor (accessories):
If the voltage at input X15.1/X15.2 on the control PCB
of the ventilation unit exceeds the set value, the air
flow rate is decreased. Below this limit the most recent
applicable air flow rate is reactivated.

Note
If humidity control via the central humidity sensor is
simultaneously active ("Humidity sensor C105"):
Control via the central humidity sensor has priority.

sensor 1:
If the measured CO

concentration is between the set
value and "CO2 sensor 1 max PPM C1C9", the venti-
lation unit can automatically and continuously adjust
the air flow rate depending on the measured value.
