CASE 3: Wrong connections between the "CHILD-1" unit and the "CHILD-2" unit
• 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: Remote controller connected to incorrect unit
• Either a temperature controller or a remote controller 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.
• The temperature controller of the “CHILD” unit will not control the unit on the system.
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
