The dark squares indicate the direction
the dipswitches should be set to.
Easy Link Connection Procedures
1. Choose one of your units as the “MASTER” unit.
2. “The MASTER”
Locate the bank of dipswitches to the right of the 7-seg. LED on the computer board of the T-
K3/T-K3-Pro that you select to be the “MASTER” unit. Change dipswitch No. 1 to “ON”. Do not
change any dipswitch settings on the “SLAVE” units.
3. Between the “MASTER” and the “SLAVE-1”
Connect the “MASTER connector” of the “MASTER unit” to the “SLAVE IN connector” of the
“SLAVE-1” unit.
4. Between the “SLAVE-1” and the “SLAVE-2”
Connect the “SLAVE OUT connector” of the “SLAVE-1 unit” to the “SLAVE IN connector” of the
“SLAVE-2” unit.
5. Between the “SLAVE-2” and the “SLAVE-3”
Connect the “SLAVE OUT connector” of the “SLAVE-2” unit to the “SLAVE IN connector” of the
“SLAVE-3” unit.
6. Make sure the “Easy Link system ON LINE” lamps of all units are lit. The numbering system
of the T-K3/T-K3-Pro 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.1 of the “MASTER” unit to “ON”, the system will not
work as an Easy Link system. The “Easy Link system ON LINE” lamps will stay unlit and
the units will work as individual units.
