Central ventilation units AIR1 XH
In order to use this function, at least one air quality sensor must be connected. The sensor-controlled operating function
can only be activated by the VOD timer.
Up to 3 different or same types of sensors can be connected to a ventilation unit with 3 free analogue inputs. The hig-
hest ventilation requirement has priority.
If a room temperature sensor is connected to analogue input AI2 (AIR1/KWL-FTF 0-10V temperature 0-10 V sensor),
only analogue inputs AI3 and AI4 will be available for the air quality sensors.
In order to connect more than 3 sensors to a ventilation unit, the optional signal converter AIR1-SK with 6 analogue
inputs and one analogue output is available. Only the same types of sensor can be connected per signal converter
AIR1-SK.
