• Indicator
- When e-ion operation starts, e-ion indicator ON.
• Remote Control Receiving Sound
- Normal Operation e-ion Operation : Beep
- e-ion Operation Normal Operation : Beep
-Stop e-ion individual Operation : Beep
- e-ion individual Operation Stop : Long Beep
• 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.
- e-ion operation status is not memorized after OFF the unit. After OFF, when the operation is ON again, air conditioner
operates without e-ion operation.
• 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 Active 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.
• Error Detection Control
When e-ion indicator blink, it indicates error listed below:
- Active e-ion Air Purifying system PCB main connector open:
• Judgment Method
- During e-ion operation (include during Patrol operation), active 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.
- Abnormal Discharge error:
• Judgment Method
- During e-ion operation, feedback voltage is-Lo (at microcontroller) is detected, it is judged abnormal discharge and
stops power supplies to the active e-ion Air Purifying system.
- Abnormal discharge is caused by ionizer or filter’s high voltage power supply short-circuits due to water or dust
adhesion, and so forth.
- When abnormal discharge occurred, every 30 minutes the unit supplies power to the active e-ion Air Purifying system.
- When abnormal discharge occurs for 24 times continuously, e-ion indicator blinks (not applicable for e-ion Check Mode,
where the error will shows immediately despite the 24 times counter)
• Troubleshooting Method
- Press “e-ion” button or “OFF/ON” button to stop the operation and check the active 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
- Active e-ion Air Purifying system breakdown error:
• Judgment Method
- When hi-feedback voltage (at microcontroller) supplied to filter during e-ion stop, active e-ion Air Purifying system
breakdown error shows immediately.
- It is due to indoor PCB or filter’s high voltage power supply damage.
- Operations except e-ion continue. Both Timer indicator and e-ion indicator blink.
• 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 active e-ion Air Purifying system during e-ion operation, e-ion indicator and Timer
indicator stop blinking.
