should be set to.
MULTI-UNIT SYSTEM FOR LARGE VOLUMES
Multiple T-M32’s can be combined for a Multi-Unit system, along with the Multiple Unit
Controller and Remote Controller (Parts TM-MC01 and TM-RE30). Each set of controllers (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.
An individual cut-off switch if hard-wired is recommended for each unit in a multi-unit system for
the purpose of maintenance.

Model T-M32
This is the connection diagram between T-M32 and
TM-MC01 for 2 to 20 water heaters. As shown is a
sample for 3 T-M32s.
・
Make sure the “7-seg LED” of all the units’
computer boards display the unit #. The TM-
MC01 automatically allocates the unit # (1-20) to
each water heater that is part of the Multi-unit
system.
