Easy Link Connection Procedures
1. Choose one of your units as the “
MASTER
” unit.
2. “
The MASTER
”
Locate the
left bank
of dipswitches to the lower of the 7-seg. LED on the computer board of
the T-M32 that you select to be the “
MASTER
” unit. Change dipswitch No. 8 to “ON”. Do not
change any of the dipswitches on the “
SLAVE
” units.
3. Between the “
MASTER
” and the “
SLAVE-1
”
Connect the “
MASTER
connector” of the “
MASTER
unit” to the
“
[1]
connector
”
of the
“
SLAVE-1
” unit.
4. Between the “
SLAVE-1”
and the “
SLAVE-2”
Connect the
“[2]
connector
”
of the “
SLAVE-1
” unit to the
“
[1]
connector
”
of the
SLAVE-2
”
unit.
5. Between the “
SLAVE-2”
and the “
SLAVE-3”
Connect the
“
[2]
connector
”
of the “
SLAVE-2
” unit to the
“
[1]
connector
”
of the “
SLAVE-3
”
unit.
6. Make sure the “7-seg LED” of all the units’ computer boards display the unit #. The
numbering system of the T-M32 automatically allocates the unit # to each water heater that is
part of the Easy-Link system.
Master unit
Unit # : 1
Slave units
Unit# : 2, 3 and 4
CAUTION
