41o Timer control When ON timer activates when unit stops, previous operation resumes and restores last saved e-ionoperation 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 e-ion operation statusis saved.o Indicator When e-ion operation starts, e-ion indicator ON.o e-ion Check Mode To check if e-ion is malfunctioning, press “e-ion” button and follow by “Check” button to enter e-ion checkmode 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-ionindicator blinks immediately.o Power failure During e-ion individual operation, if power failure occurs, after power resumes, e-ion individual operationresumes immediately. During combination operation, if power failure occurs, after power resumes, combination operationresume immediately.o Error Detection ControlWhen e-ion indicator blink, it indicates error listed below: e-ion Air Purifying system main connector to PCB is open:Judgement Method During e-ion operation (include during Patrol operation), e-ion Air Purifying system main connector toPCB is opened.Troubleshooting Methods Connect the connector or stop operation (include during Patrol operation) to cancel the blinking. Abnormal DischargeJudgement Method During e-ion operation, when feedback voltage is -Lo (at microcontroller) is detected, it is judgedabnormal 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 Purifyingsystem 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. e-ion breakdownJudgement Method When hi-feedback voltage (at microcontroller) supplied to filter during e-ion stop, due to PCB orfilter’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 e-ion Air Purifying system during e-ion operation, e-ionindicator and Timer indicator stop blinking.
