NOTE : At power supply failure or installation, indoor unit deletes the memory about remote controller. When
the power supply is turned on and indoor unit receives the first signals from the remote controller, the
remote controller number is designated as the indoor unit number. Therefore at and after the second
time indoor unit accepts the remote controller of the initial setting number.
At setting - error, turn the power supply off to cancel the individual operation and then turn the power
supply on to restart the setting.
