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.

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
WARNING communication cable. Do not splice or modify connectors.
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.
