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.
