NOTE

Notes on AUTO operation

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

• In the quiet operation mode, the airflow rate is set to a weak level.
• In DRY operation, the airflow rate setting cannot be changed.
• At smaller airflow rates, the cooling (heating) effect is also smaller.

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 29

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.

NOTE

Note on INTELLIGENT EYE operation

• INTELLIGENT EYE operation is set to blow directly on people, the air conditioner tracks you horizontally, without the air blowing directly on you.
• When the INTELLIGENT EYE sensor detects the movement of people, it adjusts the airflow direction upward (while in COOL operation) and downward (while in HEAT operation), by adjusting the flap. Depending on the setting, the louvres (vertical blades) will either direct airflow directly toward or away from people.

■ How the 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 current airflow direction is maintained.	The air conditioner will switch to energy-saving mode after 20 minutes.

* The airflow direction may differ from the illustrated direction depending on the actions and movements of the people in the areas.

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, and the INTELLIGENT EYE lamp goes off. If human movement is detected again, the INTELLIGENT EYE lamp lights up and energy saving operation terminates.
• 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^ , the operation changes the temperature by +1^ in COOL / +1^ 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^ C.
  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 could also mistakenly detect pets, sunlight, fluttering curtains and light reflected off of mirrors as passers-by.
• 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.
• NIGHT SET mode ▶Page 20 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, then starts the operation.
• The system automatically reselects setting at a regular interval to bring the indoor temperature to 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

INTELLIGENT EYE Operation

How the INTELLIGENT EYE operation works

The INTELLIGENT EYE sensor detects human movement and adjusts the right and left 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.	A person is detected in area 2.	People are detected in both areas.	No people are detected in the areas.
			When the INTELLIGENT EYE operation and the COMFORT AIRFLOW operation are used together, the unit will not blow air directly at people (only in their general direction).	The air conditioner will switch to energy-saving mode after 20 minutes.

* The airflow direction may differ from the illustrated direction depending on the actions and movements of the people in the areas.

INTELLIGENT EYE operation is useful for energy saving

Energy saving operation

• If no presence detected in the room for 20 minutes, energy saving operation starts automatically.
• 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 air intake slightly in FAN operation only.

NOTE

Notes on INTELLIGENT EYE operation

- Application range is as follows.

Horizontal angle 110° (Top view) 55° 55° 7m

- 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 air 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 7m 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.
• INTELLIGENT EYE operation will not switch on during POWERFUL operation.
• NIGHT SET mode ▶Page 21 will not switch on during use of INTELLIGENT EYE operation.
