A remote controller is not required for the Easy-Link system.
NOTICE
If running the Easy-Link system without a remote controller, please make sure the
temperature settings on ALL the units are set to the same settings. Otherwise, the
units will not operate properly.
If a 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.
