• Manual Fan Speed

Operation starts at High, Medium or Low speed set by remote control.

• Auto Fan Speed

When operation start, or shifting to thermostat ON condition from thermostat OFF condition, indoor fan operates as below.

• Manual Fan Speed

Operation starts at High, Medium or Low speed set by remote control.
However, when operation start, or during operation, fan speed control is limited due to prevent a cold draft, for example, when
heating operation start.

• Auto Fan Speed

When operation start, or shifting to thermostat ON condition from thermostat OFF condition, indoor fan operates as below.

• If thermostat is off, indoor fan fixed low speed; Louver angle fixed at upper limit, regardless remote control setting.

• When power is on, at the same time, louver start initializing toward to close Direction.
• During operation, stopping, thermostat off condition, louver angle set manual or auto depend on remote controller setting.

• Temperature range for louver control during heating operation is as follows; decide by indoor heat exchanger temperature.

• During cooling operation, outdoor fan speed changes according to outdoor pipe temperature.
• The fan speed is controlled by the timing of turning the outdoor fan ON and OFF within an interval.
• When outdoor pipe temperature increase, interval timing increased.
• Outdoor fan ON time is a variable with the range of 200ms to 2000ms.
• After 2 minutes, the outdoor pipe temperature is detected and the outdoor unit fan speed is changed automatically.

• During heating operation, the fan speed is controlled by indoor heat exchanger temperature.
• In case of twin operation, the higher indoor heat exchanger temperature is used to control the fan speed. During heating opera-

tion, the fan speed is controlled by indoor heat exchanger temperature.

• Odour cut operation removes the odour generated at indoor heat exchanger by using drain water come out from indoor heat

exchanger.

• Press “Odour” button at remote control to enable odour cut operation.
• Odour cut operation starts when compressor or thermostat is on.

• During Cooling, Soft Dry or Deice operation, drain pump operates by following the table below.
• When compressor start, drain pump operating starts after 10 seconds of indoor fan starts.

• When operation stop or thermostat is off, drain pump continue operates for 6 minutes to prevent the drain water from coming

back.

• To achieve setting temperature quickly.
• Cooling powerful operation:
• Setting temperature and thermostat shifting temperature are decrease by 2°C (lower limit 16°C).

- Airflow direction is optimized regardless the air flow setting at remote control.
- Fan speed is optimized at Hi regardless the fan speed setting at remote control.

• Soft Dry powerful operation:

- Setting temperature and thermostat shifting temperature are decrease by 2°C (lower limit 16°C).
- Airflow direction follows remote control setting.

• Heating powerful operation:

- Setting temperature and thermostat shifting temperature are increase by 2°C (upper limit 31°C).
- Airflow direction is optimized regardless the air flow setting at remote control.
- Fan speed is optimized at Hi regardless the fan speed setting at remote control.

• During powerful operation, the powerful indicator lights on.
• Powerful operation cancel when:

- Powerful operates for more than 15 minutes.
- Powerful button is pressed again.
- Operation mode changed.
- Operation stopped by remote control or emergency button.

- OFF timer is activated.

• Hot start control operates at the starting of heating operation, where [PREHEAT] displayed at wired remote control / [POWER

LED] blinking at control panel of indoor unit.

• Indoor fan stops and louver angle fixed at upper limit in spite of any setting of remote control until hot start control ends (indoor

heat exchanger temperature increases or 4 minutes past heating operation starts), fan and louver control resume.
