Air flow direction (Horizontal Vane) control:
Follow vane direction control at cooling mode.
Horizontal vane can be changed by customer during ion only operation.
2. Ion only operation can be off by pressed ION button again. (2 → 1)
3. It can be changed to previous operated mode (Auto, Cool, Dry, Fan) + ion operation by OFF/ON switch. (2 → 4)
4. During ion only operation, if power failure occur, after power resume, ionizer & air-conditioner resumes immediately.
5. After error = 24 times, (about 11h 30 min.), ion & fan off with Ion LED blinks continuously.
(Detail refer to Ionizer Error detection control.)
b. Operation Mode + Ionizer Operation.
1. Ionising Operation Start Condition
When air-conditioner unit is in "ON" condition (Cool, Dry, Fan, Auto mode) and ION operation button at remote controller is
pressed. Ionizer on & ION LED illuminates. (3 → 4)
Power LED also illuminates.
2. Ionising Operation Stop Condition
When one of the following condition is satisfied, ION operation stops.
a. Stopped by ON/OFF switch.
b. Timer OFF activates.
c. ION operation button is pressed again.
d. ION feedback signal shows error.
3. Ionizer operation status is not memorised after off. After OFF, when operation is "ON" again, air-conditioner operates without
ionizer operation.
However, during Cool mode etc + ionizer operation, if there is a power failure & then power resume, A/con shall on at that
mode + ionizer operation.
c. Timer during ionizer operation
Refer to case study in next page for detail.
8.11.1. Ionizer Error Detection Control
A. Purpose
To inform user that error occurs at ionizer system so that repairing job can be carried out.
B. Two type of error detection control:
(a) When Ionizer is ON (example case: Ionizer shorted, ionizer over current protection)
• During ionizer ON operation, when feed back voltage = Lo (micon input) is detected, Ion is OFF. If feedback = Lo for 11
hrs 30 min, ION LED blinks continuously.
• To cancel ion LED blinking, press ion button at remocon (or forcible operation sw at a/con unit). If ion button is pressed
again, ion LED blinks again.
• The error can be reset by:
i) Operation ON/OFF button press to operation OFF.
ii) Forcible switch press to operation OFF.
iii) Operation OFF due to Timer OFF reach.
iv) Timer set ON & operation from ON to OFF (only applicable to 12 hrs timer models).
(b) When Ionizer is OFF (example case: ionizer connecting wire loose)
• During air conditioner is at standby or ON operation and ionizer at OFF condition, if ionizer feed back voltage = Hi (micon
input) is detected, Ionizer breakdown detection control is activated and ion LED immediately blinks.
• To cancel Ion LED blinking, press ion button at remocon (or forcible operation sw at a/con unit). If ion button is pressed
again, ion LED blinks again.
• During ionizer at breakdown condition, if ionizer feedback voltage = Lo (become OK), ion LED will stop blinking.
