•
If there is a power failure, operation will be automatically restarted after 3 to 5 1/2 minutes when the power is resumed.
It will start with previous operation mode and airflow direction.
•
Restart time is decided randomly using 4 parameter:-
Intake air temperature, setting temperature, fan speed and Air Swing Blade position.
•
Auto Restart Control is not available when Timer or Sleep Mode is set.
•
This control can be omitted by open the circuit of JX1. (Refer Circuit Diagram)
