Remote controller custom code setting
Selecting the Remote Controller Custom Code
Use the following steps to select the custom code of the remote controller. (Note that the
air conditioner cannot receive a signal if the air conditioner has not been set for the match-
ing custom code.)
1 Press the “MODE” button for at least fi ve seconds
to display the current custom code (initially set
to A).
2 Press the “SET TEMP.” (
) ( ) button to
change the custom code between
A↔B↔C↔D
.
Match the code on the display to the air condi-
tioner custom code.
3 Press the “MODE” button again. The custom code will be changed.
If no buttons are pressed within 30 seconds after the custom code
is displayed, the display returns to the original display. In this case,
start again from step 1.
Depending on the remote controller, the remote controller custom
code may return to custom code A when the batteries are replaced.
In this case, if you use a code other than A, reset the code after
replacing the batteries.
If you do not know the air conditioner custom code setting, try each
code (A→B→C→D) until you fi nd the code which operates the air
conditioner.
12. TEST RUN
Check items
(1) Is operation of each button on the remote control unit normal?
(2) Does each lamp light normally?
(3) Do airfl ow direction louvers operate normally?
(4) Is the drain normal?
(5) Do not have an abnormal noise and vibration during operation?
Do not operate the air conditioner in test run for a long time.
[Operation method]
Depending on your installation, choose from the following:
By the wireless remote controller
To start test run, press the “START/STOP” button and the “TEST RUN” button on the
remote controller.
To end test run, press the remote controller “START/STOP” button.
By the indoor unit
To start test run, press the “MANUAL AUTO” button of the indoor unit for more than
10 seconds (forced cooling).
To end test run, press the “MANUAL AUTO” button for more than 3 seconds or press
the remote controller “START/STOP” button.
By the wired remote controller
For the operation method, refer to the installation manual and the operating manual of
the wired remote controller.
The Operation indicator lamp and Timer indicator lamp will simultaneously fl ash during the
test run mode.
Heating test run will begin in a few minutes when HEAT is selected by the remote
controller [reverse cycle model only].
13. CUSTOMER GUIDANCE
Explain the following to the customer in accordance with the operating manual:
(1) Starting and stopping method, operation switching, temperature adjustment, timer, air
fl ow switching, and other remote control unit operations.
(2) Air fi lter removal and cleaning, and how to use the air louvers.
(3) Give the operating manual to the customer.
14. ERROR CODES
If you use a wireless remote controller, the lamp on the photo detector unit will output er-
ror codes by way of blinking patterns. If you use a wired remote controller, error codes will
appear on the remote controller display. See the lamp blinking patterns and error codes in
the table. An error display is displayed only during operation.
