How to connect the CAN bus cable to the appliance
To connect the CAN bus cable to the AY10 electronic board
(Paragraph 1.5
p. 18, located in the electrical panel inside the
AY00-120 unit, Figure 4.3 p. 32, Details A and B:
1. Access the electrical board of the appliance according to the
Procedure 4.2 p. 30.
2. Connect the CAN bus cable to terminals GND, L and H (shield-
ing/ea two signal conductors) of the AY10 board.
3. Place the Jumper J1, of the AY10 board, OPEN.
4. Connect the DDC to the CAN bus cable to terminals GND, L
and H (shielding/ea two signal conductors) of the
DDC.
5. The CAN bus connection between the AY10 board and the
S61 board is pre-wired (Figure 1.14 p. 17).

Place the CLOSED J21 Jumpers (Detail A) if the node is terminal
(one connected CAN bus cable section only), or OPEN (Detail

Control with external enables
How to connect external enables
Connection of external requests is effected on the termi-
nal block located in the electrical panel inside the AY00-
120 unit.
It is required to arrange:
▶
Request devices (e.g. thermostats, timers, buttons, ...) fitted
with voltage-free NO contacts.
If you wish the heating enables of the two units to be simultane-
ous follow the connection diagram shown in Figure 4.5 p. 33.
Should you wish the enables of the two units to be independent
follow the connection diagram shown in Figure 4.6
p. 33.
