9. Turn on power to the “PARENT” unit.
Next, turn on “CHILD-1”. When the built-in controller installed in “CHILD-1” unit displays a number,
turn on “CHILD-2”.
When the built-in controller installed in the “CHILD-2” unit displays a number, turn on “CHILD-3”.
Make sure the built-in controller installed in each child unit displays each unit #. (Refer to p.40.) The
numbering system automatically allocates the unit No. to each water heater in the Easy-Link System,
in accordance with the table below.
10. Set the water temperature using the built-in temperature controller on the “PARENT” unit. It will set
the temperature for the Easy-Link System. If a remote controller is installed to the “PARENT” heater,
it will override the built-in controller.

Installaon Manual
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.
