Connection to the boiler
The sending, reception and decoding of
signals occurs through the BUS proto-
col, which puts the boiler microproces-
sors and the Zone Control 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 Zone Control wires to the
BUS terminal on the boiler P.C.B. (Fig.
6).
- Power the boiler.
- Replace the upper part of the Zone
Control by observing the sequence A-
B-C-D (Fig. 4).
NOTE: To avoid interference problems
when connecting the Zone Control and
boiler, use a shielded cable or twisted
pair cable.
