[Heating]

• According to indoor pipe temperature, automatic heating fan speed is determined as follows.

• Immediately after the fan motor started, feedback control is performed once every second.

• During fan motor on, if fan motor feedback   2550 rpm or < 50 rpm continue for 10 seconds, then fan motor error counter

increase, fan motor is then stop and restart. If the fan motor counter becomes 7 times, then H19 - fan motor error is detected.
Operation stops and cannot on back.

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.

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

1. 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. 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, expect fan only mode.
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 manual

1. 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. Fan speed for quiet operation is -1 step from setting fan speed.
3. Fan Speed Auto

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

When the powerful mode is selected, the internal setting temperature will shift to achieve the setting temperature quickly.

(a) Cooling Operation

(b) Soft Dry Operation

(c) Heating Operation

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.

60 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 above 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 operation of the unit are Hot Start, during Deice operation, operation mode judgment, or

ON timer sampling.

• If Timer LED is blinking, there is an abnormality operation occurs.
• If e-ion LED is blinking, there is an abnormality of e-ion occurs.
• If PATROL LED is blinking, there is a gas sensor error detection.

To monitor air dirtiness level by using gas sensor and activates e-ion operation whenever air is dirty.

a. Patrol operation start condition

• When the unit operation is started with “OFF/ON” button.
• When the unit stops, “Patrol” button is pressed, Patrol individual operation will start.
• During cooling only operation, “Patrol” button is pressed.
