REQUIREMENT
When the air conditioner is used for the first time, it will
take some moments after the power has been turned on
before the remote controller becomes available for
operations: This is normal and is not indicative of trouble.
• Concerning the automatic addresses (The automatic
addresses are set up by performing operations on the
outdoor interface circuit board.)
While the automatic addresses are being set up, no
remote controller operations can be performed. Setup
takes up to 10 minutes (usually about 5 minutes).
• When the power is turned on after automatic address
setup
It takes up to 10 minutes (usually about 3 minutes) for
the outdoor unit to start operating after the power has
been turned on.
Before the air conditioner was shipped from the factory,
all units are set to [STANDARD] (factory default). If
necessary, change the indoor unit settings.
The settings are changed by operating the wired remote
controller.
* The settings cannot be changed using only a
wireless remote controller, simple remote controller
or group control remote controller by itself so install
a wired remote controller separately as well.
Basic procedure for changing
settings
Change the settings while the air conditioner is not
working.
(Stop the air conditioner before making
settings.)
CAUTION
Set only the CODE No. shown in the following table: Do
NOT set any other CODE No.
If a CODE No. not listed is set, it may not be possible to
operate the air conditioner or other trouble with the
product may result.
* The displays appearing during the setting process
differ from the ones for previous remote controllers
(AMT21E, AMT31E). (There are more CODE No.)

Push and hold
button and “TEMP.”
button simultaneously for at least 4
seconds. After a while, the display flashes
as shown in the figure. Confirm that the
CODE No. is [01].
• If the CODE No. is not [01], push
button to
clear the display content, and repeat the
procedure from the beginning. (No operation of
the
remote controller is accepted for a while
after button is pushed.)
(While air conditioners are operated under the
group control, “ALL” is displayed first. When
is pushed, the indoor unit number
displayed following “ALL” is the header unit.)
