controllers with the same address on the same line.
Address 255 can be used by the Master to communicate with
all the connected equipment (broadcast mode), while with
the address 0 all the devices receive the command, but no
response is expected.
ECOM0010 can introduce a delay (in milliseconds) of the
response to the master request. This delay must be set on
QBSBNFUFS


6HGH
Each parameter modification is saved by the controller in
the EEPROM memory (100000 writing cycles), while the
setpoints are saved with a delay of 10 seconds after the last
modification.
NB: Changes made to words that are different from those
reported in the following table can lead to malfunction.
