7-7. Auto Restart Function |
7-7-1. How to Set the Auto Restart |
This unit is equipped with an Automatic restarting facility which allows the unit to restart and resume the set operating conditions in the event of a power supply shutdown without the use of the hand control.
The operation will resume without warning three minutes after the power is restored.
The Auto Restart function is set not to work on shipment from the factory, and so it is necessary to set it to function as required.
• When the system is stand-by (not running)
To set the Auto Restart function, proceed as follows: Access the TEMPORARY button located in the lower right hand corner beneath the hinged front panel of the indoor unit (please refer to section on PARTS NAME). The power supply to the unit must be on - the function will not be set if the power is off.
To enable the Auto Restart function, press the TEMPORARY button continuously for three seconds. The unit will acknowledge the setting and beep three times. The system will now restart automatically.
The above Auto Restart settings can be carried out:

7-7-2. How to Cancel the Auto Restart
To cancel the Auto Restart function, proceed as follows:
Repeat the setting procedure: the unit will acknowledge the instruction and bleep three times.
• When the system is stand-by (not running)
The system will now be required to manually restart with the remote control after the main supply is turned off.
Cancellation is carried out:

7-7-3. In Case of Power Failure during the Timer Operation
(1)If ON-TIMER operation is reserved with setting of Auto Restart operation, it is cancelled with power failure. (The OPERATION lamp on the main unit goes on and off to inform of power failure.) In that case, try to reserve ON-TIMER operation once again.
(2)If OFF-TIMER operation is reserved without setting of Auto Restart operation, the reservation is cancelled with power failure. (The OPERATION lamp on the main unit goes on and off to inform of power failure.) In that case, try to reserve OFFTIMER operation. When Auto Restart operation is set, OFF-TIMER reservation is also cancelled with power failure.
