NOTE

Notes on AUTO operation

• In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT) based on the indoor temperature and starts the operation.
• The system automatically reselects setting at a regular interval to bring the indoor temperature to the user-setting level.

Note on COOL operation

• This air conditioner cools the room by releasing the heat in the room outside.
  Therefore, the cooling performance of the air conditioner may be degraded if the outdoor temperature is high.

Note on DRY operation

- Eliminates humidity while maintaining the indoor temperature as much as possible. It automatically controls temperature and airflow rate, so manual adjustment of these functions is unavailable.

Notes on HEAT operation

• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufficient, it is recommended to use another heating appliance in combination with the air conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room. After the start of HEAT operation, it takes some time before the room gets warmer.
• In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches into defrosting operation to take away the frost.

Note on FAN operation

• This mode is valid for fan only.

COOL operation	HEAT operation	AUTO operation	DRY/FAN operation
18.0~32.0°C	10.0~30.0°C	18.0~30.0°C	The temperature setting cannot be changed.

Tips for saving energy

Keeping the temperature setting at a moderate level helps save energy.

- Recommended temperature setting for cooling: 26.0-28.0°C, for heating: 20.0-24.0°C

Cover windows with a blind or a curtain.

- Blocking sunlight and air from outdoors increases the cooling (heating) effect.

Keep the air filters clean.

- Clogged air filters cause inefficient operation and waste energy. Clean them once in about every 2 weeks. ▶ Page 39

If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn off the circuit breaker.

- The air conditioner always consumes a small amount of electricity even while it is not operating.

- This is a type of plasma discharge comprising high-speed electrons with a high oxidative capacity that is released within the unit. It decomposes odours and harmful gases. (The high-speed electrons are generated and then adsorbed within the unit ensure your safety.)

Note on flash streamer air cleaning setting

- The display automatically returns to the default screen after 60 seconds. To return to the default screen sooner, press Cancel twice.

Notes on flash streamer air cleaning operation

• The streamer discharge may generate a fizzing sound, however this does not indicate a defect.
• Do not block the air inlets of the streamer with any objects (Fig.1). Impaired airflow may result in insufficient performance or trouble with streamer operation.

• If the upward and downward airflow direction is selected, the COMFORT AIRFLOW function will be canceled.
  Priority is given to the function of whichever button is pressed last.
• If there is an obstruction under the air conditioner when using heating, the airflow may not reach the center of the room and the room may be difficult to warm up.

INTELLIGENT EYE Operation

27.0°C MON 15:30 Sensor Timer

The INTELLIGENT EYE sensor detects human movement and adjusts airflow direction. It can be set to avoid people or to direct airflow specifically at people. If no one is in the room for more than 20 minutes, the operation automatically changes to energy saving operation.

CAUTION

• Do not place large objects near the INTELLIGENT EYE sensor. Also keep heating units and humidifiers outside the sensor's detection area. This sensor can detect undesirable objects.
• Do not hit or violently push the INTELLIGENT EYE sensor. This can lead to damage and malfunction.

■ To start

Press Sensor and select the desired mode.

• Each time is pressed, a different setting option appears on the LCD.

("") or "will remain on the LCD.) To keep INTELLIGENT EYE operation active, do not use it in combination with auto swing airflow direction modes.

■ To cancel

Press Sensor until no icon is displayed.

NOTE

Notes on combining INTELLIGENT EYE operation and COMFORT AIRFLOW operation

• INTELLIGENT EYE operation can operate in combination with COMFORT AIRFLOW operation.
When the INTELLIGENT EYE operation is set to blow directly on people and COMFORT AIRFLOW operation is activated simultaneously, the air conditioner tracks you horizontally, without the air blowing directly on you.
- The airflow rate will be set to AUTO. If the up and down airflow direction is selected, the COMFORT AIRFLOW operation will be canceled. Priority is given to the function of whichever button is pressed last.

■ How INTELLIGENT EYE operation works

The INTELLIGENT EYE sensor detects human movement and adjusts the right and left airflow direction. If no one is in the room for more than 20 minutes, the operation automatically changes to energy saving operation. The INTELLIGENT EYE sensor works differently depending on the situation.

[Example]

	A person is detected in area 1. area 2.	A person is detected in	People are detected in both areas.	No people are detected in the areas.
			The airflow is directed to Area 1.	The air conditioner will switch to energy-saving mode after 20 minutes.
			The current airflow direction is maintained.

INTELLIGENT EYE operation is useful for energy saving

Energy saving operation

• If no presence detected in the room for 20 minutes, the energy saving operation will start.
• This operation changes the temperature by -2^ in HEAT / +2^ in COOL / +2^ in DRY operation from the set temperature.
  When the room temperature exceeds 30^ C, the operation changes the temperature by +1^ C in COOL / +1^ C in DRY operation from the set temperature.
• This operation decreases the airflow rate slightly in FAN operation only.

NOTE

Notes on INTELLIGENT EYE operation

• Application range is as follows.

Vertical angle 90° (Side view) 5m 90°

Horizontal angle 110° (Top view) 55° 55° 5m

- While the air conditioner is in INTELLIGENT EYE operation, the louvres adjust the airflow direction if there are people in the sensing areas of the INTELLIGENT EYE so that the leftward or rightward airflow will not be directed to the people. If no people are detected in either area 1 or 2 for 20 minutes, the air conditioner switches to the energy-saving mode with the set temperature shifted by 2^ .

The air conditioner may switch to the energy-saving operation even if there are people in the areas.

This may occur depending on the clothes the people are wearing, if there is no movement of the people in the areas.

• The airflow direction from the louvres will be leftward if there are people in both areas 1 and 2. The air will also flow left if there is a person right in front of the sensor as the sensor judges that there are people in both areas.
• Due to the position of the sensor, people might be exposed to the airflow of the indoor unit if they are close to the front side of the indoor unit. If there are people close to the front side of the indoor unit or in both areas, it is recommended to use the COMFORT AIRFLOW and INTELLIGENT EYE operations simultaneously. Using both modes together, the air conditioner will not direct the airflow towards the people.
• The sensor may not detect moving objects further than 5m away. (Please see the application range)
• Sensor detection sensitivity changes according to the indoor unit location, the speed of passers-by, temperature range, etc.
• The sensor could also mistakenly detect pets, sunlight, fluttering curtains and light reflected off of mirrors as passers-by.
• NIGHT SET mode ▶ Page 26 will not switch on during use of INTELLIGENT EYE operation.

Notes on AUTO operation

• In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT) based on the indoor temperature and starts the operation.
• The system automatically reselects setting at a regular interval to bring the indoor temperature to the user-setting level.

Note on COOL operation

• This air conditioner cools the room by releasing the heat in the room outside.
  Therefore, the cooling performance of the air conditioner may be degraded if the outdoor temperature is high.

Note on DRY operation

- Eliminates humidity while maintaining the indoor temperature as much as possible. It automatically controls temperature and airflow rate, so manual adjustment of these functions is unavailable.

Notes on HEAT operation

• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufficient, it is recommended to use another heating appliance in combination with the air conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room. After the start of HEAT operation, it takes some time before the room gets warmer.
• In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches into defrosting operation to take away the frost.

Note on FAN operation

Notes on AUTO operation

• In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT) based on the indoor temperature and starts the operation.
• The system automatically reselects setting at a regular interval to bring the indoor temperature to the user-setting level.

Note on COOL operation

• This air conditioner cools the room by releasing the heat in the room outside.
  Therefore, the cooling performance of the air conditioner may be degraded if the outdoor temperature is high.

Note on DRY operation

- Eliminates humidity while maintaining the indoor temperature as much as possible. It automatically controls temperature and airflow rate, so manual adjustment of these functions is unavailable.

Notes on HEAT operation

• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufficient, it is recommended to use another heating appliance in combination with the air conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room. After the start of HEAT operation, it takes some time before the room gets warmer.
• In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches into defrosting operation to take away the frost.

Note on FAN operation

• This mode is valid for fan only.

INTELLIGENT EYE Operation

27.0°C MON 15:30 Sensor Timer

The INTELLIGENT EYE sensor detects human movement and adjusts airflow direction. It can be set to avoid people or to direct airflow specifically at people. If no one is in the room for more than 20 minutes, the operation automatically changes to energy saving operation.

CAUTION

• Do not place large objects near the INTELLIGENT EYE sensor. Also keep heating units and humidifiers outside the sensor's detection area. This sensor can detect undesirable objects.
• Do not hit or violently push the INTELLIGENT EYE sensor. This can lead to damage and malfunction.

■ To start

Press Sensor and select the desired mode.

• Each time Sensor is pressed, a different setting option appears on the LCD.

NOTE

Notes on combining INTELLIGENT EYE operation and COMFORT AIRFLOW operation

• INTELLIGENT EYE operation can operate in combination with COMFORT AIRFLOW operation.
When the INTELLIGENT EYE operation is set to blow directly on people and COMFORT AIRFLOW operation is activated simultaneously, the air conditioner tracks you horizontally, without the air blowing directly on you.
- The airflow rate will be set to AUTO. If the up and down airflow direction is selected, the COMFORT AIRFLOW operation will be canceled. Priority is given to the function of whichever button is pressed last.

■ How INTELLIGENT EYE operation works

The INTELLIGENT EYE sensor detects human movement and adjusts the right and left airflow direction. If no one is in the room for more than 20 minutes, the operation automatically changes to energy saving operation. The INTELLIGENT EYE sensor works differently depending on the situation.

[Example]

	A person is detected in area 1. area 2.	A person is detected in	People are detected in both areas.	No people are detected in the areas.
			The airflow is directed to Area 1.	The air conditioner will switch to energy-saving mode after 20 minutes.
			The current airflow direction is maintained.

INTELLIGENT EYE operation is useful for energy saving

Energy saving operation

• If no presence detected in the room for 20 minutes, the energy saving operation will start.
• This operation changes the temperature by -2^ in HEAT / +2^ in COOL / +2^ in DRY operation from the set temperature.
  When the room temperature exceeds 30^ C, the operation changes the temperature by +1^ C in COOL / +1^ C in DRY operation from the set temperature.
• This operation decreases the airflow rate slightly in FAN operation only.

NOTE

Notes on INTELLIGENT EYE operation

• Application range is as follows.

Vertical angle 90° (Side view) 5m 90°

Horizontal angle 110° (Top view) 55° 55° 5m

- While the air conditioner is in INTELLIGENT EYE operation, the louvres adjust the airflow direction if there are people in the sensing areas of the INTELLIGENT EYE so that the leftward or rightward airflow will not be directed to the people. If no people are detected in either area 1 or 2 for 20 minutes, the air conditioner switches to the energy-saving mode with the set temperature shifted by 2^ .

The air conditioner may switch to the energy-saving operation even if there are people in the areas.

This may occur depending on the clothes the people are wearing, if there is no movement of the people in the areas.

• The airflow direction from the louvres will be leftward if there are people in both areas 1 and 2. The air will also flow left if there is a person right in front of the sensor as the sensor judges that there are people in both areas.
• Due to the position of the sensor, people might be exposed to the airflow of the indoor unit if they are close to the front side of the indoor unit. If there are people close to the front side of the indoor unit or in both areas, it is recommended to use the COMFORT AIRFLOW and INTELLIGENT EYE operations simultaneously. Using both modes together, the air conditioner will not direct the airflow towards the people.
• The sensor may not detect moving objects further than 5m away. (Please see the application range)
• Sensor detection sensitivity changes according to the indoor unit location, the speed of passers-by, temperature range, etc.
• The sensor could also mistakenly detect pets, sunlight, fluttering curtains and light reflected off of mirrors as passers-by.
• NIGHT SET mode ▶ Page 26 will not switch on during use of INTELLIGENT EYE operation.

NOTE

Notes on AUTO operation

• In AUTO operation, the system selects an appropriate operation mode (COOL or HEAT) based on the indoor temperature and starts the operation.
• The system automatically reselects setting at a regular interval to bring the indoor temperature to the user-setting level.

Note on COOL operation

• This air conditioner cools the room by releasing the heat in the room outside.
  Therefore, the cooling performance of the air conditioner may be degraded if the outdoor temperature is high.

Note on DRY operation

- Eliminates humidity while maintaining the indoor temperature as much as possible. It automatically controls temperature and airflow rate, so manual adjustment of these functions is unavailable.

Notes on HEAT operation

• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufficient, it is recommended to use another heating appliance in combination with the air conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room. After the start of HEAT operation, it takes some time before the room gets warmer.
• In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches into defrosting operation to take away the frost.

Note on FAN operation

• This mode is valid for fan only.

Tips for saving energy

Keeping the temperature setting at a moderate level helps save energy.

- Recommended temperature setting for cooling: 26.0-28.0°C, for heating: 20.0-24.0°C

Cover windows with a blind or a curtain.

- Blocking sunlight and air from outdoors increases the cooling (heating) effect.

Keep the air filters clean.

• Clogged air filters cause inefficient operation and waste energy. Clean them once in about every 2 weeks. ▶ Page 39

If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn off the circuit breaker.

- The air conditioner always consumes a small amount of electricity even while it is not operating.
