Easy-Link System - State Water Heaters 310C Installation Manual And Owner's Manual

The 510C model water heaters can
be connected together to work as a
multiple-unit manifold system.
• The Easy-Link System allows up
to 4 units to manifold together
(connected with communication
cables).
• A communication cable (gray
color) comes with each 510C
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 15,000 BTU/h and 796,000 BTU/h.
• 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.
CAUTION
• A remote controller is not required for an Easy-Link System. However, it does
NOTICE
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 automatically be set to the same temperature that is set on the remote.
1. Make sure the power to the heaters is turned off.
2. Verify the DIP switch set temperatures of all units within the system. Every water heater must be
set to the same set temperature. If a remote controller (9009069005/TM-RE42) 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 at the bottom left of the computer board of the unit that you
select to be the "PARENT" unit. Change DIP switch No. 1 on the lower bank of DIP switches to the
ON position. See the computer board diagram as shown on 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.
6. Between the "CHILD-1" and the "CHILD-2" units:
Connect the "2" connector of the "CHILD-1" unit to the "1" connector of the "CHILD-2" unit.
7. Between the "CHILD-2" and the "CHILD-3" units:
Connect the "2" connector of the "CHILD-2" unit to the "1" connector of the "CHILD-3" unit.
8. Verify that all cables are connected like the diagram (B).
