•
•
• The mode judging temperature and standard setting temperature can be increased by 2°C, by open the circuit of JX1 at indoor
electronic controller.
8.6. Powerful Mode Operation
•
•
•
• Purpose of this operation is to obtain the setting temperature quickly.
•
•
•
• When the Powerful Mode is set, the set temperature will be automatically decreased 3°C against the present setting
temperature (Lower temperature: 16°C).
•
•
•
• This operation automatically will be running under SHi Fan Speed (Cooling), Lo- Fan Speed (Soft Dry).
•
•
•
• Vertical Airflow Direction:-
- In “Manual” setting, the vane will automatically shift down 10° lower than previous setting.
- In “Auto” setting, the vane will automatically swing up and down. However the lower limit will be shifted 10° downward.
•
•
•
• Powerful Mode will operate for 15 minutes only, after that it will shift back to previous operation mode.
•
•
•
• Powerful Mode will stop if:-
- Powerful mode button is pressed again.
- Stopped by ON / OFF switch.
- Timer OFF activates.
- Quiet mode button is pressed.

8.7. Random Auto Restart Control
•
•
•
• If there is a power failure during air conditioners operation, operation will be automatically restarted after 3 to 4 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 is set.
•
•
•
• This control can be omitted by open the circuit of JX2. (Refer Circuit Diagram)

Follow vane direction control at cooling mode.
Horizontal vane can be changed by customer during ion only operation.
2. Ion only operation can be off by pressed ION button again. (2
→ 1)
3. It can be changed to previous operated mode (Auto, Cool, Dry, Fan) + ion operation by OFF/ON switch. (2
→ 4)
4. During ion only operation, if power failure occur, after power resume, ionizer & air-conditioner resumes immediately.
5. After error = 24 times, (about 11h 30 min.), ion & fan off with Ion LED blinks continuously.
(Detail refer to Ionizer Error detection control.)
