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.

NOTE: The dark squares indicate the direction the DIP switches should be set to.
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.
