tion 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 cascade as
a single heat capacity generator:

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 ZONA
MIX code 8092252. Both require the
board housing kite code 8092236.
Carry out the electrical connections as indi-
