1. Purpose

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

2. Control Condition

a. 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.

b. 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.

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.

3. Control Content

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.

Auto Fan Speed for e-ion operation switches between HLo and CLo at pattern below:

b. Airflow direction control

• During any operation mode combines with e-ion operation, air flow direction follows respective operation mode.
• During e-ion individual operation, 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.

c. Timer control

• When ON timer activates when unit stops, previous operation resumes without e-ion 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.

d. Indicator

• When e-ion operation starts, e-ion indicator ON.

e. e-ion Check Mode

• To check if e-ion is malfunctioning, during e-ion operation press “e-ion” button for 15 seconds and release to enter e-ion

Check Mode and supplies power to the e-ion AIR PURIFYING SYSTEM.

• If abnormal discharge is detected at filter (short-circuited) due to water or dust adhesion, etc., the e-ion indicator blinks

immediately.

f. Power failure

• During e-ion individual operation, if power failure occurs, after power resumes, e-ion individual operation resumes

immediately.

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

g. Error Detection Control

When e-ion indicator blink, it indicates error listed below:

a. e-ion AIR PURIFYING SYSTEM main connector to PCB is open:

Judgment Method

• During e-ion operation (include during Patrol operation), e-ion AIR PURIFYING SYSTEM main connector to PCB is

opened.

Troubleshooting Methods

• Connect the connector or stop operation (include during Patrol operation) to cancel the blinking.

b. Abnormal Discharge

Judgment Method

• During e-ion operation, when feedback voltage is-Lo (at micro controller) is detected, it is judged abnormal discharge and

stops power supplies to the e-ion AIR PURIFYING SYSTEM.

• The unit retries after 30 minutes and repeat for 24 times. (not applicable for e-ion Check Mode)

Troubleshooting Method

• Press “e-ion” button or “OFF/ON” button to stop the operation and check the e-ion AIR PURIFYING SYSTEM main

connector to PCB.

• After that, press “e-ion” button again to confirm the e-ion indicator not blinking.
• The 24 times counter will be clear after 10 minutes of normal operation or when operation stops.

Error Reset Method

• Press “OFF/ON” button to OFF the operation.
• Press AUTO OFF/ON button at indoor unit to OFF the operation.
• OFF Timer activates.
• Press “e-ion” button during e-ion individual mode.
• Power supply reset.

c. e-ion breakdown

Judgment Method

• When hi-feedback voltage (at micro controller) supplied to filter during e-ion stop, due to PCB or filter's high voltage power

supply damage.

• Operations except e-ion continue. Both Timer indicator and e-ion indicator blinks.

Troubleshooting Method

• Press “e-ion” button or “OFF/ON” button to stop the operation.
• Change main circuit board or filter's high voltage power supply.
• When lo-feedback voltage supplied to e-ion AIR PURIFYING SYSTEM during e-ion operation, e-ion indicator and Timer

indicator stop blinking.

1. AUTO OPERATION MODE

The Auto operation will be activated immediately once the Auto OFF/ON button is pressed. This operation can be use to
operate air conditioner with limited function if remote control is misplaced or malfunction.

2. TEST RUN OPERATION (FOR PUMP DOWN/SERVICING PURPOSE)

The Test Run operation will be activated if the Auto OFF/ON button is pressed continuously for more than 5 seconds. A “beep”
sound will occur at the fifth seconds, in order to identify the starting of Test Run operation.

3. REMOTE CONTROL RECEIVING SOUND OFF/ON MODE

The Remote Control Receiving Sound OFF/ON operation will be activated if (within 20 seconds of Test Run Operation) the
Auto OFF/ON button is pressed for more than 5 seconds. 2 “beep” sound will occur at to identify the starting of Remote
Control Receiving Sound Off/On Mode.

Press “Auto OFF/ON button” to toggle remote control receiving sound.
- Short “beep”: Turn ON remote control receiving sound.
- Long “beep”: Turn OFF remote control receiving sound.

After Auto OFF/ON Button is pressed, the 20 seconds counter for Remote Control Receiving Sound OFF/ON Mode is
restarted.

• There are 4 type of remote control transmission code could be selected and stored in EEPROM of indoor unit. The indoor unit

will only operate when received signal with same transmission code from remote control. This could prevent signal interference
when there are 2 or more indoor unit installed nearby together.

• To change remote control transmission code, short or open jumpers at the remote control printed circuit board.

• During Remote Control Receiving Sound OFF/ON Mode, press any button at remote control to transmit and store the desired

transmission code to the EEPROM.
