The above connection diagram is an example of how to connect 4 T-M50s together in a
Multi-Unit System. Up to 10 T-M50s can be connected in this fashion.
•
Make sure the “7-seg LED” of all the units’ computer boards display the unit #. The TM-
MC01 automatically allocates the unit # (1 to 10) to each water heater that is part of the
Multi-unit system.

The dark squares indicate the direction the dipswitches should be set to.
Please refer to the TM-MC01 manual for further instructions of the Multi-Unit system
