EASY-LINK SYSTEM
(Available on the 510 (T-D2) model only)
The 510 (T-D2) 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 Easy-Link System allows up to 4 units to manifold together.
•
A communication cable (gray color) comes with each 510 (T-D2) 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.
-Easy-Link Connection Procedures-
1. Make sure the power to the heaters are off.
2. Verify the DIPswitch set temperatures of all units within the system. Every single water heater must
be set to the same set temperature. If an TM-RE30 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 DIPswitches to the right of the 7-seg. LED on the computer board of the unit
that you select to be the
“PARENT”
unit. Change DIPswitch No. 1 on the
right bank of DIPswitches
to the ON position
. See the computer board diagram as shown in the next page. Do not change any
DIPswitches on any of the
“CHILD”
units.
