Installation and Connection
Control overview
Wiring of group unit, KaControl, max. 30 units
Master and last slave unit need to be equipped with
a 120 Ohm on-site resistor.
If you wish, you can separately measure the
temperature for each unit via a room or air
intake sensor.
CAN bus card con
fi
guration using a DIP switch
setting (identical for all CAN bus cards):
1. Disconnect the KaCool.
2. Remove the CAN bus card from the basic PCB.
3. Set the DIP switch according to the illustration.
4. Plug the CAN bus card into the basic PCB.
5. Connect the BUS cable.
