The remote control displays 'STANDBY' for up to 30 minutes after the first power-up following a breaker power supply input or recovery from a power failure. This is not a failure but a normal refrigerant oil protection control to safeguard the compressor.
Click steps to track your progress.
Do not attempt to operate the unit; this is a normal protection cycle.
Wait patiently for up to 30 minutes for the 'STANDBY' display to turn off automatically.
Allow the unit to complete its refrigerant oil protection control before resuming normal operation.
If 'STANDBY' persists for longer than 30 minutes or does not clear, consult your dealer for further assistance.
Ensure stable power supply to prevent frequent power interruptions.
