Error Detection Control

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

o Active e-ion Air Purifying system PCB main connector open:

ƒJudgment Method

During e-ion operation (include during Patrol operation), Active e-ion Air Purifying system main connector to PCB is opened.

ƒTroubleshooting Methods

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

oAbnormal Discharge error:

ƒJudgment 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)

ƒTroubleshooting Method

Press “PATROL/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.

ƒError 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

Power supply reset

oActive e-ion Air Purifying system breakdown error:

ƒJudgment 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.

ƒTroubleshooting Method

Press “PATROL/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.
