12.9. Ionizer Operation
Purpose
To provide fresh air effect to users by discharging minus ion to air.
Control Condition
a. Ionizer Only Operation.
1. When air-conditioner unit is at “OFF” condition (standby) and ION operation button at remote control is pressed.
Fan & ionizer on, ION LED illuminates, but power LED maintain off. (1o2)
However, fan speed can be adjusted later by customer during this operation.
Airflow direction (Horizontal Vane) control:
Follow vane direction control at cooling mode.
Horizontal vane can be changed by customer during ion only operation.
b. Operation Mode + Ionizer Operation
1. Ionizer Operation Start Condition.
When air conditioner unit is in “ON” condition (Heat, Cool, Dry, Auto mode) and ION operation button at remote control is
pressed. Ionizer on & ION LED illuminates. (3o4)
Power LED also illuminates.
2. Ionizer 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 feedback signal shows error.
3. Ionizer operation status is not memorised by microcontroller. After OFF, when operation is “ON” again, air conditioner
operates without ionizer operation.
12.9.1. Ionizer Error Detection
• There are 3 errors detect by the unit.
a. Connector Open Detection
- If the connector is pulled out during ionizer operation, ion LED blinks.
- Once the ionizer connector reconnect to the unit, ion LED stops blinking.
b. Ionizer Control Discharge Error Detection
- When ionizer generator is short circuit due to water or dust adhesion, power supplies to ionizer is stopped for 30 minutes
and resume power supply after 30 minutes. If this situation happens for 24 times, ion LED blinks.
- The connector resets when the ionizer operates normally for 10 minutes or the unit switched off.
