displayed following “ALL” is the header unit.)
REQUIREMENT
When the air conditioner is used for the
fi
rst 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.
