Function
If there is a power cut when the unit is operating, it will automatically resume the same operating
mode when the power is restored.
Caution
When performing maintenance and the power supply is to be shut off, be sure to turn the remote
controller’s ON/OFF switch OFF first.
Shutting the power supply switch off while the ON/OFF switch is still ON is dangerous because
the “power failure automatic reset function” will cause the indoor fan to start turning
immediately, or the outdoor unit fan to automatically start turning three minutes after the power
supply is turned back on.
