Connecting two “PARENT connectors” together from two separate units may damage
the computer board. The communication cable has a female end and a male end so
it’s impossible to have a PARENT ‐to‐ PARENT connection with the communication
cable. Do not splice or modify connectors.
 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
temperature 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.
CASE 3:
If you connect the “PARENT connector” of the “CHILD‐1” unit to the “[1] connector” of the “CHILD‐2”
unit, the “CHILD‐2” unit will operate as an individual unit, and will not be part of the Easy‐Link system.
CASE 4:
 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.
Prohibited
Wrong connection between the “CHILD‐1” unit and the “CHILD‐2” unit
Remote controller
connected to
incorrect unit
