• Power failure
o During e-ion individual operation, if power failure occurs, after power resumes, e-ion individual operation
resumes immediately.
o During combination operation, if power failure occurs, after power resumes, combination operation resume
immediately.
o 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
o To check if e-ion is malfunctioning, press “e-ion” button and then follow by “Check” button to enter e-ion
Check Mode and supplies power to the Active e-ion Air Purifying System.
o 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:
o 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.
o 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
