-Easy-Link Connection Procedures-
1. Make sure the power to the heaters are off.
2. Verify the DIP switch set temperatures of all units within the system. Every single water heater must be
set to the same set temperature. If a remote controller is used, it should be installed to the
“PARENT”
unit. The remote will set the temperature for the entire system.
3. Select one unit to be the
“PARENT”
unit. The
“PARENT”
unit should be one of the end units.
4.
“PARENT”
unit:
Locate the two banks of DIP switches to the right of the 7-seg. LED on the computer board of the unit
that you select to be the
“PARENT”
unit. Change DIP switch No. 1 on the
right bank of DIP switches
to the ON position
. See the computer board diagram as shown in the next page. Do not change any
DIP switches on any of the
“CHILD”
units.
5. Between the
“PARENT”
and the
“CHILD-1”
units:
Connect the
“PARENT”
connector of the
“PARENT”
unit to the
“1”
connector of the
“CHILD-1”
unit
using the supplied linking cable.

EASY-LINK SYSTEM
(510 model only)
-General-
The 510 model water heaters can be connected with other allowable heaters (see the table
below) with communication cables to work as a multiple-unit manifold system.
•
The built-in Easy-Link System allows up to 4 units to manifold together.
•
A communication cable (gray color) comes with each 510 model.
You can manifold from 2 to 4 units without the need for a multi-unit controller. A 4-unit system
has full automatic modulation between 11,000 BTU/h and 796,000 BTU/h.

*If the 510U model or 510U 200 series model is incorporated in an Easy-Link Sytem with the other mod-
els in the table above, the DIP switch of all the 510U and the 510U 200 series computer boards must
be changed. Please refer to the manual of 510U model or 510U (T-D3U) 200 series model on Easy-Link
System for more detail.
•
The Easy-Link System is limited to up to
4 units
. If you connect more than 4 units,
only the first 4 units will work as a part of the Easy-Link System. The other additional
units will not work.
•
Only listed models on the table above can be combined together as an Easy-Link
System
.
These models cannot be combined together with other models not listed
on the table above.
•
A remote controller is not required for an Easy-Link System. However, it does provide
for more temperature options and ease of maintenance.
•
If a remote controller is used, the temperature on all the units in the system will auto-
matically be set to the same temperature that is set on the remote.
•
When a remote is used in an Easy-Link System, it must be connected to the parent unit.
