Connection to the boiler
The sending, receiving and decoding of sig-
nals occurs through the BridgeNet® BUS
protocol, which puts the boiler and the sys-
tem interface in contact with each other.
- connect a pair of wires to the BUS con-
nector on the boiler P.C.B.
- connect the pair of wires running from
the BUS connector to the system inter-
face terminal.
NOTE: To avoid interference problems
when connecting the room sensor and
boiler, use a shielded cable or twisted
pair cable.
