8.10. Powerful Mode Operation
Purpose of this operation is to be obtain the setting temperature quickly.
1. Cooling and Soft Dry Mode
• 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).
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 upper and lower limit will be shifted 10°
downward.
downward.
2. Heating Mode
• When the Powerful Mode is set, the set temperature will be automatically increased 3°C against the present setting
temperature (Higher temperature: 30°C).
• The Fan Speed will shift as shown below:
• Vertical Airflow Direction:-
In “Manual” setting, the vane will automatically shift down 5° lower than previous setting.
In “Auto” setting, the vane will automatically shift between upper and lower limit depending on the intake air temperature as

Heating Mode, Airflow Direction Auto-Control. However the upper and lower limit will be shifted 5° downward.
3. Powerful mode will operate for 15 minutes only.
4. Powerful Mode will stop if:
• Powerful mode button is pressed again.
• Stopped by ON / OFF switch.
• Timer-off activates.
• Quiet mode button is pressed.
• Operating mode is changed.
• Stopped by ON / OFF switch.

8.11. Ionizer Operation
Purpose
To provide fresh air effect to user by producing minus ion in discharge air.
Control Condition
a. Ionizer Only Operation.
1. When air-conditioner unit is at “OFF” condition (standby) and ION operation button at remocon is pressed.
Fan & ionizer on, ION LED illuminates, but power LED maintain off. (1
→ 2)
However, fan speed can be adjusted later by customer during this operation.
Air flow direction (Horizontal Vane) control:
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, Heat, Cool, Dry) + 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.)
b. Operation Mode + Ionizer Operation.
1. Ionising Operation Start Condition
When air-conditioner unit is in “ON” condition (Heat, Cool, Dry, Auto mode) and ION operation button at remote controller
is pressed. Ionizer on & ION LED illuminates. (3
is pressed. Ionizer on & ION LED illuminates. (3
→ 4)
Power LED also illuminates.
2. Ionising Operation Stop Condition
When one of the following condition is satisfied, ION operation stops.
a. Stopped by ON/OFF switch.
b. Timer OFF activates.
c.
ION operation button is pressed again.
d. ION feedback signal shows error.

Case 1a: Ionizer only operation (12h delay timer ON)
Case 2a: Ionizer only operation (24h real time timer ON)
Case 1b: Ionizer only operation (12h delay timer OFF)
Case 2b: Ionizer only operation (24h real time timer OFF)
3. Ionizer operation status is not memorised after off. After OFF, when operation is “ON” again, air-conditioner operates without
ionizer operation.
However, during Cool mode etc. + ionizer operation, if there is a power failure & then power resume, A/con shall on at that
mode + ionizer operation.
mode + ionizer operation.
c. Timer during ionizer operation
Refer to case study in next page for detail.
8.11.1. Ionizer Error Detection Control
A. Purpose
To inform user that error occurs at ionizer system so that repairing job can be carried out.
B. Two type of error detection control:
(a) When Ionizer is ON (example case: Ionizer shorted, ionizer over current protection)
• During ionizer ON operation, when feed back voltage = Lo (micon input) is detected, Ion is OFF. If feedback = Lo for 11
hrs 30 min, ION LED blinks continuously.
• To cancel ion LED blinking, press ion button at remocon (or forcible operation sw at a/con unit). If ion button is pressed
again, ion LED blinks again.
• The error can be reset by:
i) Operation ON/OFF button press to operation OFF.
ii) Forcible switch press to operation OFF.
iii) Operation OFF due to Timer OFF reach.
iv) Timer set ON & operation from ON to OFF (only applicable to 12 hrs timer models).
(b) When Ionizer is OFF (example case: ionizer connecting wire loose)
• During air conditioner is at standby or ON operation and ionizer at OFF condition, if ionizer feed back voltage = Hi (micon
input) is detected, Ionizer breakdown detection control is activated and ion LED immediately blinks.
• To cancel Ion LED blinking, press ion button at remocon (or forcible operation sw at a/con unit). If ion button is pressed
again, ion LED blinks again.
• During ionizer at breakdown condition, if ionizer feedback voltage = Lo (become OK), ion LED will stop blinking.
