d. AUTO COMFORT button is pressed.
e. ECONAVI button is pressed.
f.  Mild Dry Cooling button is pressed.

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, expect 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 manual

1. 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. Fan speed for quiet operation is reduced from setting fan speed.

b. Fan Speed Auto

1. Indoor FM RPM depends on pipe temp sensor of indoor heat exchanger.

• When the powerful mode is selected, the internal setting temperature will shift lower up to 2

“C (for Cooling/Soft Dry) or higher up

to 3.5

“C (for Heating) than remote control setting temperature for 20 minutes to achieve the setting temperature quickly.

• There are 2 sets of ON and OFF timer available to turn the unit ON or OFF at different preset time.
• If more than one timer had been set, the upcoming timer will be displayed and will activate in sequence.

• ON timer 1 and ON timer 2 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 1 and OFF timer 2 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.
3. This control can be omitted by open the circuit of JP1 at indoor unit printed circuit board.

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 Patrol sensor and to maintain air freshness by activates e-ion operation

• Patrol operation starts condition

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

• Patrol operation stops condition (when any of the following condition is fulfilled):

- When “OFF/ON” button is selected.
- During any operation with Patrol, “PATROL/e-ion” button is pressed.
- When OFF Timer activates.

• To disable the Patrol Operation during unit starts (default) with “OFF/ON” button

- Press “Set” button continuously for 15 seconds by using pointer during Air Conditioner is OFF condition to enter internal

setting mode.

- Press “Timer Decrement” button to select “Pt dFLt”.
- Press “Timer Set” button to toggle Patrol operation default OFF/ON.

- Long “beep”: Turn OFF Patrol operation default.
- Short “beep”: Turn ON Patrol operation default.

• Patrol 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 Clean.

- After that, Patrol 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 level, based on the Air Dirtiness Value:

- Air Dirtiness level 0: Clean - Patrol LED = blue color
- Air Dirtiness level 1: Moderate - Patrol LED = orange color
- Air Dirtiness level 2: Contaminated - Patrol LED = red color

• Dirtiness level sensitivity adjustment

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

1. Press and release “SET” button.
2. Press Timer   / Timer   button to select sensitivity. (Air 1 “Low Sensitivity 

 Air 2 “Standard” (Default) 

 Air 3 “High

Sensitivity”)

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.

• e-ion Control

- e-ion operation starts condition

- When dirtiness at level 2.
- 2 minutes after stabilization time.
- 4 hours at level 0.

- e-ion operation time

- 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 11 minutes or more, e-ion operation stops.

• Dirtiness Level and fan speed

- When e-ion operation starts, the fan speed increases based on dirtiness level:

- 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.

• 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.

• Indicator

- When patrol is selected, patrol sensor indicator ON.

• Remote Control Receiving Sound

• Timer Control

- When ON timer activates when unit stops, previous operation resumes and restored last saved Patrol operation status.
- When ON timer activates during any operation, no change and carry on current operation.
- When OFF timer activates during any operation, all operation stops and the latest Patrol operation status is saved.

• Power Failure Control

- During Patrol individual operation, if power failure occurs, after power resumes, Patrol individual operation resumes

immediately.

- During combination operation, if power failure occurs, after power resumes combination operation resume immediately.

This operation provides clean air by producing negative ions to attract dust captured at the positively charged e-ion filters.

a. e-ion operation start condition

• During unit running at any operation mode, if “e-ion” operation is selected, combination operation (operation mode + e-ion

operation) starts.

• During unit is OFF, if “e-ion” operation is selected, e-ion individual operation starts.

b. e-ion operation stop condition

• When “OFF/ON” button is pressed to stop the operation.
• When “PATROL/e-ion”  button is pressed.
• When OFF Timer activates.

c. e-ion operation pause condition

• When indoor fan stop (during deice, odor cut control, thermostat off, etc.). e-ion operation resume after indoor fan restarts.
• When indoor intake temperature   40

“C. e-ion operation resume after indoor intake temperature < 40“C continuously for 30

minutes.

a. Indoor fan control

• During any operation mode combines with e-ion operation, fan speed follows respective operation mode.
• During e-ion individual operation - 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.
