Applicable controls
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 control 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 control 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
control.
* The settings cannot be changed using only a
wireless remote control, simple remote control or
group control remote control by itself so install a
wired remote control 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.
