Mitsubishi Electric · MSZ-AP Air Conditioners
The air conditioner is equipped with an auto restart function. If the power supply is interrupted (for example, during a blackout) while the unit is operating, it will automatically resume operation with the previous settings once power is restored. This is a designed feature, not a fault, unless unwanted.
Click steps to track your progress.
Understand that this is a normal function designed to restore operation automatically after power outages.
To prevent the unit from restarting automatically, ensure it is manually turned OFF (using the E.O. SW or remote controller) before cutting the main power supply.
If you wish to permanently disable the auto restart function, consult a service representative, as this typically requires a specific procedure.
Refer to the operating instructions for full details on how the auto restart feature works and its management.
