Connection to the boiler
The sending, reception and decoding of
signals occurs through the BridgeNet®
BUS protocol, which puts the boiler mi-
croprocessors and the room sensor into
contact.
- Insert the wires into the appropriate
slot and connect them to terminals
A
and
C
(Fig. 5).
- Disconnect the boiler from the power
supply.
- Connect the room sensor wires to the
BridgeNet-
BUS
terminal on the boiler
P.C.B. (Fig. 6).
- Power the boiler.
- Replace the upper part of the room
sensor by observing the sequence A-
B-C-D (Fig. 4).
NOTE:
To avoid interference problems
when connecting the room sensor and
boiler, use a shielded cable or twisted
pair cable.
