Test Operation 67
(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.
(12) Setting of Normal Airflow
Make the following setting according to the ceiling height. The setting position No. is set to “01” at the factory.
 In the Case of FXAQ, FXHQ
 In the Case of FXFQ12~30
 In the Case of FXFQ36
Caution 1. The air conditioner starts operation suddenly after power failure reset or
the main power supply turned on again. Consequently, the user might be
surprised (with question for the reason why).
2. In the service work, for example, turning off the main power switch during
the unit is in operation, and turning on the switch again after the work is
completed start the unit operation (the fan rotates).
