1. When one of the following conditions is satisfied, quiet operation stops:

a. Powerful button is pressed.
b. Stop by OFF/ON switch.

c. Timer “off” activates.

d. Quiet button is pressed again.

2. When quiet operation is stopped, operation is shifted to normal operation with previous setting.
3. When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
4. When operation mode is changed, quiet operation is shifted to quiet operation of the new mode.
5. During quiet operation, if timer “on” activates, quiet operation maintains.
6. After off, when on back, quiet operation is not memorised.

1. Auto fan speed is changed from normal setting to quiet setting of respective fan speed.

This is to reduce sound of Hi, Me, Lo for 3dB.

2. Manual fan speed for quiet operation is 1 step from setting fan speed.
3. Outdoor fan speed is changed to Q-Lo
4. Compressor frequency reduced.

To provide quiet heating operation compare to normal operation.

a. Quiet operation start condition
•  When “quiet” button at remote control is pressed.

Quiet LED illuminates.

b. Quiet operation stop condition

1. When one of the following conditions is satisfied, quiet operation stops:

a. Powerful button is pressed.
b. Stop by OFF/ON switch.

c. Timer “off” activates.

d. Quiet button is pressed again.

2. When quiet operation is stopped, operation is shifted to normal operation with previous setting.
3. When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
4. When operation mode is changed, quiet operation is shifted to quiet operation of the new mode, except fan only mode.
5. During quiet operation, if timer “on” activates, quiet operation maintains. 
6. After off, when on back, quiet operation is not memorised.

a. Fan Speed Auto
•  Indoor FM RPM depends on pipe temperature sensor of indoor heat exchanger.

Auto fan speed is changed from normal setting to quiet setting of respective fan speed.
This is to reduce sound of Hi, Me, Lo for 3dB.

b.  Fan Speed Manual
•  Manual fan speed for quiet operation is - 1 step from setting fan speed.

c.  Compressor frequency reduced.

When the powerful mode is selected, the internal setting temperature will shift higher up to 3.5

qC (for Heating) or lower up to 2qC

(for Coolong/Soft Dry) than remote control setting temperature for 20 minutes to achieve the setting temperature quickly.

ON timer can be set using remote control, the unit with timer set will start operate earlier than the setting time. This is to provide a
comfortable environment when reaching the set ON time.

60 minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate for 30 seconds to determine the
indoor intake air temperature and outdoor air temperature in order to judge the operation starting time.

From the above judgment, the decided operation will start operate earlier than the set time as shown below.

OFF timer can be set using remote control, the unit with timer set will stop operate at set time.

1. When the power supply is cut off during the operation of air conditioner, the compressor will re-operate within three to four

minutes (there are 10 patterns between 2 minutes 58 seconds and 3 minutes 52 seconds to be selected randomly) after
power supply resumes. 

2. This type of control is not applicable during ON/OFF Timer setting.

Note:

• If POWER LED is blinking, the possible operation of the unit are Hot Start, during Deice operation, operation mode judgment, or

ON timer sampling.

• If Timer LED is blinking, there is an abnormality operation occurs.
• If e-ion LED is blinking, there is an abnormality of e-ion occurs.
• If PATROL LED is blinking, there is a gas sensor error detection.

To monitor air dirtiness level by using gas sensor and activates e-ion operation whenever air is dirty.

a. Patrol operation start condition

• When the unit operation is started with “OFF/ON” button.
• When the unit stops, “Patrol” button is pressed, Patrol individual operation will start.
• During cooling only operation, “Patrol” button is pressed.

b. Patrol operation stop condition

When any of the following condition is fulfilled:
• When “OFF/ON” button is pressed.
• During any operation with Patrol, “Patrol” button is pressed again.
• When “e-ion” button is pressed.
• When OFF Timer activates.

c. Patrol operation disable

• To disable the Patrol Operation during unit start (default) with “OFF/ON” button, press “Patrol” button and hold for 5 seconds,

then release.

• To disable the Patrol Operation, press “Patrol” button and hold for 15 seconds, then release.

a. Gas Sensor Control

• First 2 minutes from Patrol function activates is stabilization time, during stabilization time, no air dirtiness level is monitored.

The Air Dirtiness level is set to level 2.

• After that, gas sensor starts to record the resistance value at fixed interval. Higher resistance value indicates cleaner air.
• The air dirtiness level is monitored by comparing the current resistance value with maximum resistance value from time to time

to get the Air Dirtiness Value.

• There are 3 air dirtiness levels, based on the Air Dirtiness Value:

- Air Dirtiness level 0: Clean
- Air Dirtiness level 1: Moderate
- Air Dirtiness level 2: Contaminated

• Dirtiness level sensitivity adjustment

It is possible to change the gas sensor sensitivity, where the Threshold value (G1 ~ G4) will be shifted accordingly:

1. Press and release “SET” buttton.
2. Press “Timer increment” / “Timer decrement” button to select sensitivity. (Low 

 Standard (Default) 

 High)

3. Confirm setting by pressing “Timer Set” button. LCD returned to original display after 2 seconds.
4. LCD returned to original display if remote control does not operate for 30 seconds.

b. e-ion Control

• When dirtiness level is 1 or 2, e-ion operation starts.
• If dirtiness level improves from level 2 to level 1, the unit carries out level change after 60 seconds.
• When dirtiness level returns to level 0 continuously for 10 minutes or more, e-ion operation stops.

Dirtiness Level Shift
• For Auto Fan Speed, the fan speed increased based on dirtiness level:

c. Indoor Fan Control

• During any operation mode combines with Patrol operation, fan speed follows respective operation mode.
• During Patrol individual operation if e-ion starts, only Auto Fan Speed and no Powerful operation is allowed. Even if “Fan 

Speed” button is pressed, no signal is sent to air conditioner, and no change on LCD display.

• During Patrol individual operation if e-ion stops, Indoor Fan stop operation.

d. Airflow direction (Horizontal, Vertical) Control

• During any operation mode combines with Patrol operation, airflow direction follows respective operation mode.
• During Patrol individual operation if e-ion starts, only Auto Air Swing is allowed. Even if “Air Swing” button is pressed, no signal

is sent to air conditioner, and no change on LCD display.

• During Patrol individual operation if e-ion stops, Airflow direction louver closed.

e. Indicator

• When Patrol operation starts, Patrol Sensor indicator ON.
• When e-ion operation starts based on dirtiness level, e-ion indicator ON.
