How to connect the CAn BUs cable to the Comfort Control Panel
The CAN bus cable is connected to the specific orange connector (P8) supplied with the
CCP in a bag.
Before working on the Comfort Control Panel, make sure that it is off.
The CCP, like the controller on the appliance, has jumpers that must be moved so that it
can be configured as an intermediate or terminal node. The position of the jumpers on
a new CCP is CLOSED.
To connect the CAN bus cable to a CCP:
You will need: the Comfort Control Panel not powered up.
Open the Comfort Control Panel’s electrical panel with the handle on its left.

52. If necessary, open the CCI’s back panel (4 screws); after jumpers J21
have been correctly positioned, close the cover again and retighten the 4 bolts.
Cut a length of cable long enough to allow installing it without kinking.
