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 automatically
address setup, it takes up to 10 minutes (usually
about 3 minute) 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 and simple remote controller by itself
so install a wired remote controller separately as well.
