2 .2 .5 Connection of optional air quality sensors

The following air quality sensors can be connected for sensor-controlled operation:
KWL-CO2
KWL-VOC
KWL-FTF
AIR1-CO2 K
Connection of air quality sensors:
The power supply (24 V DC) must be connected according to the wiring diagram (see wiring diagram).
The signal cables are connected according to the wiring diagram via the analogue inputs AI2, AI3 and AI4.
Connection information:
• If a room temperature sensor is connected to analogue input AI2, only analogue inputs AI3 and AI4 are available for
air quality sensors.
• Up to 3 different or same types of sensors can be connected to a ventilation unit with 3 free analogue inputs. The
highest ventilation requirement has priority.
• If more than 3 sensors are connected, the signal converter AIR1-SK with 6 analogue inputs and one analogue out-
put is available. Only the same type of sensor can be connected to a signal converter.
An output of 56,7 W or 88,1 W is available for the connection of air quality sensors. However, this decreases depending
on additionally connected accessories.
Thus, the available 24 V power supply must be considered for the connection of sensors based on the table.
AIR1 XH 1000-5500: The available DC output for 24 V accessory components is 56,7 W.
