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 cascade as
a single heat capacity generator:
P = P x No.

lows:

nect the second RS-485 board equipped

provided in the kit.
CAUTION: Insert the wired connector
with caution.
- Set the DIP SWITCH of the new board in
. MODBUS mode.
