Depending on the installed environment, correction of the room temperature sensor may
be required.
Select the appropriate control setting according to the installed environment.
The temperature correction values show the difference from the Standard setting “00”
(manufacturer’s recommended value).

Remote controller custom code setting
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 custom code.)
1.
Press the START/STOP button until only the clock is displayed on the remote controller display.
2. Press the MODE button for at least fi ve seconds to display the
current custom code (initially set to A).
3. Press the SET TEMP. (
/ ) button to change the custom
code between
A↔B↔C↔D
.
Match the code on the display to the air conditioner custom code.
4. Press the MODE button again to return to the clock display. The
custom code will be changed.
If no buttons are pressed within 30 seconds after the custom code is displayed, the
system returns to the original clock display. In this case, start again from step 1.
The air conditioner custom code is set to A prior to shipment.
The remote controller resets to custom code A when the batteries in the remote
controller are replaced. If you use a custom code other than custom code A, reset
the custom code after replacing the batteries. If you do not know the air conditioner
custom code setting, try each of the custom codes (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 controller 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 (with “TEST RUN” button)
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].
