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
• Unless you change dipswitch No. 8 of the “MASTER” unit to “ON”, the system will not
work as an Easy Link system. The units will work as individual units.
