nication of at least two boilers in cascade
and is performed by requesting another
RS-485 board provided in the kit code
8092244.
ATTENTION: Communication will occur
only with the MASTER boiler, (boiler
with PAR 15 = 0), interpreting the casca-
de as a single heat capacity generator:

PAR 15 = 0
) with the wired
connector provided in the kit.
CAUTION: Insert the wired connector
with caution.
- Set the DIP SWITCH of the new board
in MODBUS mode.
- Close the lid of the second board.
- Choose the communication configu-
ration suited to the MODBUS network
(PAR 17 INST) according to
Table PAR

.
RS-485 connection to the INSOL/ZONA
MIX (fig. 4/e)
The RS-485 board can be connected
to optional INSOL kit code 8092254 or
MIXED ZONE code 8092252. Both require
the board housing kite code 8092236.
Carry out the electrical connections as
indicated in the figure.
CAUTION: For electrically connecting
the INSOL/
