Outdoor fan motor is operated with one fan speed only. It starts when compressor starts operation and it stops 30 seconds after
compressor stops operation.

1. There are two types of airflow, vertical airflow (directed by horizontal vane) and horizontal airflow (directed by vertical vanes).
2. Control of airflow direction can be automatic (angles of direction is determined by operation mode, heat exchanger

temperature and intake air temperature) and manual (angles of direction can be adjusted using remote control).

1. Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as stated

above. For heating mode operation, the angle of the vane depands on the indoor heat exchanger temperature as Figure 1
below. When the air conditioner is stopped using remote control, the vane will shift to close position.

2. Manual vertical airflow direction can be set using remote control; the angles of the vane are as stated above and the positions

of the vane are as Figure 2 below. When the air conditioner is stopped using remote control, the vane will shift to close
position.

• The horizontal airflow direction louvers can be adjusted manually by hand.

To provide quiet cooling operation compare to normal operation.

b. Quiet operation stop condition

1. When one of the following conditions is satisfied, quiet operation stops:

a.Powerful button is pressed.
b.Stop by OFF/ON switch.
c.Timer “off” activates.
d.Quiet button is pressed again.

2. When quiet operation is stopped, operation is shifted to normal operation with previous setting.
3. When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
4. When operation mode is changed, quiet operation is shifted to quiet operation of the new mode, except ion only operation.
5. During quiet operation, if timer “on” activates, quiet operation maintains.
6. After off, when on back, quiet operation is not memorised.

1. Auto fan speed is changed from normal setting to quiet setting of respective fan speed.

This is to reduce sound of Hi, Me, Lo for 3dB.

2. Manual fan speed for quiet operation is -1 step from setting fan speed.

To provide quiet heating operation compare to normal operation.

a. Quiet operation start condition

• When “quiet” button at remote control is pressed.

Quiet LED illuminates.

b. Quiet operation stop condition

1. When one of the following conditions is satisfied, quiet operation stops:

a. Powerful button is pressed.
b. Stop by OFF/ON switch.
c. Timer “off” activates.
d. Quiet button is pressed again.

2. When quiet operation is stopped, operation is shifted to normal operation with previous setting.
3. When fan speed is changed, quiet operation is shifted to quiet operation of the new fan speed.
4. When operation mode is changed, quiet operation is shifted to quiet operation of the new mode, expected ion only

operation.

5. During quiet operation, if timer “on” activates, quiet operation maintains.
6. After off, when on back, quiet operation is not memorised.

a. Fan speed auto

1. Indoor FM RPM depends on pipe temp sensor of indoor heat exchanger. 

Auto fan speed is changed from normal setting to quiet setting of respective fan speed. 
This is to reduce sound of Hi, Me, Lo for 3dB.

b. Fan speed manual

1. Manual fan speed for quiet operation is -1 step from setting fan speed.

To achieve the setting temperature quickly.

a. Powerful operation start condition

When the “powerful” button at remote control is pressed, Powerful LED illuminates

b. Powerful operation stop condition

1. When one of the following conditions is satisfied, quiet operation stops:

a. Powerful button is pressed again
b. Quiet button is pressed
c. Stop by OFF/ON switch
d. Timer OFF is pressed again

2. When Powerful operation is stopped, operation is shifted to normal operation.

a. Fan speed

1. Indoor fan speed depends on indoor intake temperature and remote control setting temperature. Fan speed is changed

from normal setting to Powerful setting of respective fan speed.

b. Temperature shifting

1. Internal setting temperature shift depends on indoor pipe temperature. Temperature is decreased (Cooling and Soft Dry

operation) or increased (Heating operation) accordingly.

ON timer can be set using remote control, the unit with timer set will start operate earlier than the setting time. This is to provide a
comfortable environment when reaching the set ON time.

70 minutes before the set time, indoor (at fan speed of Lo-) and outdoor fan motor start operate for 30 seconds to determine the
indoor intake air temperature and outdoor air temperature in order to judge the operation starting time.

From the judgment, the decided operation will start operate earlier than the set time as shown below.

OFF timer can be set using remote control, the unit with timer set will stop operate at set time.

1. When the power supply is cut off during the operation of air conditioner, the compressor will re-operate within three to four

minutes (there are 10 patterns between 2 minutes 58 seconds and 3 minutes 52 seconds to be selected randomly) after
power supply resumes.

2. This type of control is not applicable during ON/OFF Timer setting.

Note:

• If POWER LED is blinking, the possible operations of the unit are Hot Start, during Deice operation, operation mode judgement,

or ON timer sampling.

• If Timer LED is blinking, there is an abnormality operation occurs.

Purpose
To provide fresh air effect to users by discharging minus ion to air.

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. (1

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. (3

o4)

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.

• 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.
