Auto Restart after Power Failure Reset
For the air conditioners with no setting for the function, the units will be left in the stop condition when the power
supply is reset automatically after power failure reset or the main power supply is turned ON again after once
turned OFF. However, for the air conditioners with the setting (same as factory setting), the units may start
automatically after power failure reset or the main power supply turned ON again (return to the same operation
condition as that of before power failure).
For the above reasons, when the unit is set enabling to utilize “Auto restart function after power failure reset”,
utmost care should be paid for the occurrence of the following situation.

Caution The air conditioner starts operation suddenly after power failure reset or
when the main power supply is turned on again. Consequently, the user
might be surprised and wonder why this has happened. In service work, for
example, turning off the main power switch while the unit is in operation,
and turning on the switch again after the work is completed start unit
operation (the fan rotates).
