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.
1.
Open the Comfort Control Panel’s electrical panel with the handle on its left.
2.
Depending on the type of node being configured, set the CCI’s jumpers J21 as shown in detail "A" or detail "B" in Figure
6.12 p. 39. 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.
3.
Cut a length of cable long enough to allow installing it without kinking.
4.
Remove the sheath for a length of approximately 70-80 mm, taking care not to cut the shielding (metallic shield and/or alu-
minium sheet and, if present, the bare connector in contact with the shield) and wires contained inside.
5.
Roll the shielding and connect it to a 4-mm eyelet terminal, as illustrated in Figure 6.11 p. 39, details C and D. Now proceed
as follows:
6.
If the CCP is a terminal node of the network connect the three coloured wires to the orange connector "P8", as shown in detail
"A" of Figure 6.12 p. 39. Observe the terminal markings L, H, GND (on the CCI's board at the base of the socket "P8") which
are given both in Table 6.2 p. 36 and in the example.
7.
If the CCP is an intermediate node repeat the operations from step 2 to step 4 for the other length of CAN bus cable re-
quired. Connect the six coloured wires to the orange connector "P8", following the instruction provided in detail "B" of Figure
6.12 p. 39. Observe the terminal markings L, H, GND (on the CCI's board at the base of the socket "P8") which are given both
in Table 6.2 p. 36 and in the example.
8.
Insert the orange connector "P8" with the wires first into the opening prepared in the cover of the CCI, and then into the ap-
propriate socket on the CCI itself, making sure it is correctly inserted.
9.
Use the rear cover bolts located near the CAN BUS socket to secure the 4 mm eyelet (or 2 eyelets) (detail D, Figure 6.11 p. 39).
The cable should be secured against pulling out.
The CCI has jumpers J21: the position of the jumpers, depends if the CCI is an intermediate or terminal node, must be as
shown in Figure 6.12 p. 39.
