64 Configuring the Remote Controller System
1. Press the Down button on the remote controller
displaying “MAIN” to set its operation mode to
“SUB.”
Then, press the OK button to set the operation
mode to Sub.
2. “SL.xx” appears on the display.
It represents the standby status to receive the
sub remote controller ID from the main remote
controller synced to the front panel of the water

3. When the ID is assigned, the ID appears and
flashes on the LCD display for 2 seconds.
4.6 Multi Remote Controller
System
The multi remote controller system (30022717A)
consists of one main remote controller and one sub
remote controller. The system must have only one
main remote controller.
4.6.1 Initially Setting the Multi Remote
Controller System
If you turn on the water heater with the front panel
connected to two remote controllers, one of the
controllers is set to the main controller randomly.
The other controller will display “MAIN” on its LCD
display and you have to set its operation mode to
Sub.
The remote controller that does not display “MAIN”
is already operating as the main controller, you don’t
have to set its operation mode.
You can set the operation mode of the remote
controller that displays “MAIN.” When you set the
controller as a sub, the multi remote controller
system configuration completes.
Note
If you press the OK button on the
controller displaying “MAIN” and set
its operation mode to Main while
the main controller has already been
determined, the other controller will
display “MAIN” to indicate that you
must set the main and sub operation
modes properly.
