• To monitor air dirtiness level by using Patrol sensor and to maintain air freshness by activates e-ion operation.

• 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.

• 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.

• 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, Patrol LED turns blue color.

- 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: Dirty                       - 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 (Patrol LED turns red).
- 2 minutes after stabilization time (Patrol LED turns red).
- 4 hours at level 0 (Patrol LED turns red).

- e-ion operation time

- If dirtiness level improves from level 2 to level 1 (Patrol LED from red to orange), the unit carries out level change after 60

seconds.

- When dirtiness level returns to level 0 (Patrol LED turns blue) 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.

39

• 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 operation starts, Patrol LED is ON with 3 different colors:

- Then e-ion operation starts based on dirtiness level, both Patrol LED and e-ion LED are ON.

- Remote Control Receiving Sound

- Timer Control

- When ON timer activates when unit stops, previous operation resumes without Patrol operation.
- When ON timer activates during any operation, no change and carry on current operation.
- When OFF timer activates during any operation, all operation stops.

- 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.

- Error Detection Control

- The Patrol error detection control starts once the power is supplied to Patrol sensor. However, the error will display when

the Patrol operation is ON.

- Error detection method:

1. If the Patrol sensor is opened circuit continuously for 6 hours, Patrol sensor error occurs. However, the error will

display only when the Patrol operation is ON.

- Patrol Sensor Control after error occurs.

1. During any operation mode combines with Patrol operation.
a. Power supply to Patrol sensor is OFF.
b. Air conditioner normal mode operation continues with Patrol LED blinking.

c. The Patrol LED continues blinking if the patrol operation is ON and stops blinking if the Patrol operation is OFF.

- During Patrol individual mode.

1. Power supply to Patrol sensor is OFF.
2. Patrol LED blinks.
3. The Patrol LED continues blinking if the patrol operation is ON and stops blinking if the Patrol operation is OFF.

- Error cancel condition:

1. Power supply reset.

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

• e-ion operation start condition

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

operation) starts.

- During unit is OFF, if “e-ion” button is pressed, e-ion individual operation starts.

• e-ion operation stop condition

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

• 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.

• 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.
