Easy-link System
The 710 can be connected with other heaters of the same
model with communication cables to work as a multiple
manifold system.
• The Easy-Link system can connect up to 4 units.
• A communication cable (gray color) comes with each
unit. The cables use 18 gauge wire and can be up to
76.2m (250 ft.) long all together.
You can manifold from 2 units to 4 units without a multi-sys-
tem controller. A 4-unit system has full automatic modulation
between 24,000 BTU/h and 960,000 BTU/h.

CAUTION
The Easy-Link system is limited to 4
units. If you connect more than 4 units,
the first 4 units will work as part of the
Easy-Link system, but the other addi-
tional units will only work as individual
units.
The 710 cannot be linked with other
different tankless models in the Easy-
Link system. •

Easy-Link Connection Procedures
1. Choose one of your units as the “PARENT” unit.
2. “The PARENT”: Locate the left bank of DIPswitches
to the lower of the 7-seg. LED on the computer board
of the 710 that you select to be the “PARENT” unit.
Change DIPswitch No. 8 to “ON”. Do not change any of
the DIPswitches on the “CHILD” units.
3. Between the “PARENT” and the “CHILD-1”: Connect
the “PARENT connector” of the “PARENT unit” to the “[1]
connector” of the “CHILD-1” unit.
4. Between the “CHILD-1” and the “CHILD-2”: Connect
the “[2] connector” of the “CHILD-1” unit to the “[1] con-
nector” of the "CHILD-2” unit.
5. Between the “CHILD-2” and the “CHILD-3”: Connect
the “[2] connector” of the “CHILD-2” unit to the “[1] con-
nector” of the “CHILD-3” unit.
6. Make sure the “7-seg LED” of all the units’ computer
boards display the unit #. The numbering system of
the 710 automatically allocates the unit # to each water
heater that is part of the Easy-Link system.
PARENT unit Unit #: 1
CHILD units Unit #: 2, 3 and 4
The dark squares indicate the direction the DIPswitches
should be set to.
