MULTI-UNIT SYSTEM FOR LARGE VOLUMES
Multiple 710 (T-M32) models can be combined for a Multi-Unit system, along with the Multiple
Unit Controller and Remote Controller (Parts 9007675005 (TM-MC01) and 9007603005 (TM-
RE30)). Each set of controllers (one 9007675005 (TM-MC01) and one 9007603005 (TM-
RE30)) can control from 2 units to 20 units for commercial or residential applications. For a 20-
unit system, the computer can modulate between the usages of 24,000 BTU/h to 4.8 Million
BTU/h.
An individual cut-off switch if hard-wired is recommended for each unit in a multi-unit system for
the purpose of maintenance.

This is the connection diagram between 710
(T-M32) and 9007675005 (TM-MC01) for 2 to
20 water heaters. As shown is a sample for 3
water heaters.
Make sure the “7-seg LED” of all the units’
computer boards display the unit #. The Multi-unit
controller automatically allocates the unit # (1-20)
to each water heater that is part of the Multi-unit
system.
