 If a remote controller (optional) is used, it has to be connected to the “PARENT” unit. If the
remote controller is connected to a “CHILD” unit, it will only control that particular individual
“CHILD” unit and will not control the Easy-Link system as a whole.
MULTI-UNIT SYSTEM FOR LARGE VOLUMES
Multiple 910 (T-M50) 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 (Parts 9007675005 (TM-MC01) and 9007603005 (TM-RE30))
can control from 2 units to 10 units for commercial or residential applications. For a 10-unit
system, the computer can modulate between the usages of 15,000 BTU/h to 3.8 Million BTU/h.
 The remote controller is not required for the Easy-Link system.
 If running the Easy-Link system without the remote controller, please make
sure the dipswitch settings for the temperature, outdoor, and direct-vent
settings on ALL the units are set to the same settings. Otherwise, the units
may not operate properly.
 If the remote controller is used, the temperature on all the units in the
system will automatically be set to the same temperature that is set on the
remote. However, even with the remote, the outdoor and direct-vent
dipswitch settings still need to be set to the same settings on all the units.
