Connection to the boiler
The sending, receiving and decoding of
signals occurs through the BridgeNet®
BUS protocol, which puts the boiler and
the system interface in contact with each
other.
- connect a pair of wires to the BUS
connector on the boiler P.C.B.
- connect the pair of wires running
from the BUS connector to the sys-
tem interface terminal.
