Panasonic Air Conditioner

d. Airflow direction (Horizontal, Vertical) Control

• During any operation mode combines with Patrol operation, airflow direction follows respective operation mode.

• During Patrol individual operation if e-ion starts, 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.

• During Patrol individual operation if e-ion stops, Airflow direction louver closed.

e. Indicator

• When Patrol operation starts, Patrol Sensor indicator ON.

• When e-ion operation starts based on dirtiness level, e-ion indicator ON.

• When ON timer activates when unit stops, previous operation resumes without Patrol 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.

h. Power failure

• During Patrol individual operation, if power failure occurs, after power resumes, Patrol individual operation resumes immediately.

• During combination operation, if power failure occurs, after power resumes combination operation resume immediately.

12.10. e-ion Operation

A. Purpose

This operation provides clean air by producing negative ions to attract dust captured at the positively charged e-ion filters.

B. Control Condition

a. e-ion operation start condition

• During unit running at any operation mode, if “e-ion” button is pressed, combination operation (operation mode + e-ion operation) starts.

• During unit is OFF, if “e-ion” button is pressed, e-ion individual operation starts.

b. e-ion operation stop condition

• When “OFF/ON” button is pressed to stop the operation.

• When “e-ion” button is pressed again.

• When “Patrol” button is pressed.

• When OFF Timer activates.

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: 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 immediately.

• 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)

34

Troubleshooting Method

• Press “e-ion” button or “OFF/ON” button to stop the operation and check the 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.

Error 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.

• Press “e-ion” button during e-ion individual mode.

• Power supply reset.

iii. e-ion breakdown

Judgement Method

• When hi-feedback voltage (at microcontroller) supplied to filter during e-ion stop, due to PCB or filter’s high voltage power supply damage.

• Operations except e-ion continue. Both Timer indicator and e-ion indicator blink.

Troubleshooting Method

• Press “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 e-ion Air Purifying system during e-ion operation, e-ion indicator and Timer indicator stop blinking.
