c) e-ion operation pause condition
•
When indoor fan stop (during deice, odor cut control, thermostat off, etc.). e-ion operation resume after
indoor fan restarts.
•
When indoor intake temperature ≥ 40°C. e-ion operation resume after indoor intake temperature < 40°C
continuously for 30 minutes.
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:
0.5 x (HLo+CLo)
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
LED blinks immediately.
f) 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.
g) Error Detection Control
•
When e-ion LED blink, it indicates error listed below:
(1) e-ion Air Purifying system main connector to PCB is open:
Judgment Method
(a) During e-ion operation (include during Patrol operation), e-ion Air Purifying system main
connector to PCB is opened.
Troubleshooting Methods
(a) Connect the connector or stop operation (include during Patrol operation) to cancel the blinking.
(2) Abnormal Discharge
Judgment Method
(a) 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.
(b) The unit retries after 30 minutes and repeat for 24 times. (not applicable for e-ion Check Mode)
