(10) Auto Restart after Power Failure Reset
For the air conditioners with no setting for the function (same as factory setting), 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, 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.
(11) Airflow when Cooling Thermostat is OFF
This is used to set airflow to "LL airflow" when cooling thermostat is OFF.

at the factory.

the unit is in operation, and turning on the switch again after the work is
completed start the unit operation (the fan rotates).
