C.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, airflow 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 immedi-
ately.
• 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:
i. 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 to PCB is opened.
Troubleshooting Methods
• Connect the connector or stop operation (include during Patrol operation) to cancel the blinking.
ii. Abnormal Discharge
Judgement Method
• During e-ion operation, when feedback voltage is -Lo (at microcontroller) 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)
