Multi-unit System For Large Volumes
Multiple 710 models can be combined for a Multi-Unit sys-
tem, along with the Multiple Unit Controller and Remote
Controller (Parts TM-MC01 and TM-RE30). Each set of con-
trollers (one TM-MC01 and one 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.

Multi-Unit Controller (TM-MC01) and Temperature Remote
Controller (TM-RE30) wiring:
This is the connection diagram between 710 and 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.
