The slave number is also used to generate a
start delay. Slave 01 will have one-second
delay on receiving a switch on command
from the master. Slave 02 will have a two
second delay etc. This reduces the gas
surge and electrical surge by preventing all
the slaves from coming on together.
The Master sends the time and date to the
slaves to lock their clocks to the same time.
The time is updated at one-minute intervals.
Any change of time and date at the master
will be sent to the slaves. The master checks
each slave on the system for a burner
failure. Should a failure occur this would
appear not only on the slave controller but
also on the master. The slave number that
failed will in indicated in the digital display.
The failed slave can be reset from either the
master panel or the slave concerned. The
reset signal from the master is only sent to
the failed unit.
The slaves will follow operating instructions
from the master, or can be set to run from
their own internal settings. Each individual
slave has its own temperature sensor for
sensing temperature in its area. Therefore
the set point temperatures are set at each
individual panel.

Setting passwords
The system sends 12V signals back and
forwards between one unit designated as a
Master Controller and the others which
must be set as slaves. The unit is supplied
set to ‘Energy Mizor 00’, this is a safe
configuration which disables the
communication line signals.
Having wired the system set the one unit
that is to be the Master panel to ‘Master 00’.
All other units must be set as slaves with
numbers ‘01’ upwards.
Note No two slaves should have the same
number and only one panel may be
identified as a master.
