(For Cooling Operation or cooling region of Soft Dry Operation)

• The Quiet operation is to provide quiet/cooling operation condition compare to normal operation.
• Once the Quiet Mode is set at the remote control, the Quiet Mode LED illuminated. The sound level will reduce around 2 dB (A)

for Lo fan speed or 3 dB(A) for Hi/Me fan speed against the present operation sound level.

• Manual Fan Speed:-

- RPM control during Lo cool

- RPM control during Hi & Me cool

• Auto Fan Speed:-

• Quiet operation stops when:-

- Quiet button is pressed again.
- Stopped by OFF/ON operation button.
- Timer OFF activates.
- Powerful button is pressed.

• When the ON Timer is set by using the remote control, the unit will start to operate slightly before the set time, so that the room

will reach nearly to the set temperature by the set time.

• For Cooling and Soft Dry operation, the operation will start 15 minutes before the set time.
• For Automatic operation, the indoor fan will operate at SLo speed for 20 seconds, 15 minutes before the set time to detect the

intake air temperature to determine the operation mode. The operation indication lamp will blink at this time.

38

• When the OFF Timer is set by using the remote control, the unit will stop operate according to the desired setting.

Notes

1. By pressing ON/OFF operation button, the ON Timer or OFF Timer setting will not be cancelled.
2. To cancel the previous timer setting, press CANCEL button.
3. To activate the previous timer setting, press SET button.
4. If main power supply is switched off, the Timer setting will be cancelled.

• If there is a power failure during operation, the air conditioner will automatically restart after 3 to 4 minutes when the power is

resumed.

• It will start with previous operation mode and airflow direction.
• If there are more than one air conditioner unit in operation and power failure occur, restart time for each unit to operate will be

decided randomly using 4 parameters:- intake air temperature, setting temperature, fan speed and air swing louver position.

• This Random Auto Restart Control is not available when Timer is set.

• Long beep sound will be heard when:

- Stopping the air conditioner using ON/OFF switch.
- Disable e-ion and Pastrol operation.

• Short beep sound will be heard for others setting.

1. Purpose

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

2. Control Condition

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.

3. Control Content

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 level, 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:

a. Press and release “SET” button.

b. Press “Timer increment” / “Timer decrement” button to select sensitivity. (Low <

–

> Standard (Default) <

–

> High)

c. Confirm setting by pressing “Timer Set” button. LCD returned to original display after 2 seconds.

d. 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:
