Operation mode

AUTO : During operation mode selection the POWER indicator blinks.

• Unit selects operation mode every 10 minutes according to setting temperature and room temperature.

HEAT : Unit takes a while to warm up. The POWER indicator blinks during this operation.

COOL : Provides efficient comfort cooling to suit your needs.

DRY : Unit operates at low fan speed to give a gentle cooling operation.

FAN : To circulate air in the room.

i AUTO-X : The fast cooling is ideal when you come home on a hot day.

Energy saving temperature setting

Operating the unit within the recommended temperature range may save energy.

HEAT : 20.0 °C ~ 24.0 °C / 68 °F ~ 75 °F.

COOL : 26.0 °C ~ 28.0 °C / 79 °F ~ 82 °F.

Air flow direction

In COOL/DRY mode:
If AUTO is set, the flaps swings left/right and up/down automatically.

In i AUTO-X mode:
If AUTO is set, the horizontal flap is fixed at the lower position and shift to the upper position after reaches set temperature and the vertical flap swing according to activity detection. If manual is set, the horizontal flap and vertical flap are fixed at the predetermined position.

In HEAT mode:
If AUTO is set, the horizontal flap is fixed at the predetermined position. The vertical flap swings left/right after the temperature rises.

Auto restart control

If power is resumed after a power failure, the operation will restart automatically after a period of time with previous operation mode and airflow direction.

• This control is not applicable when TIMER is set.

nanoe-G in-filter deactivation

Depending on the unit’s accumulated operation time, nanoe-G in-filter deactivation may activate only once a day after the unit turned off.

To remove the moisture left in the internal parts, the fan will operate for 30 minutes with flap opened slightly. This process only applicable when the unit is operated in COOL/DRY mode before turned off. Then, nanoe-G deactivates viruses/bacteria on the filter for 2 hours with fan stopped and flap closed.

Do not turn off the power supply during this operation. After power failure, this operation will not resume.

ECONAVI

Econavi with intelligent eco sensors

Intelligent eco sensors detect potential waste of energy using the human activity sensor and sunlight sensor.

The human activity sensor scans areas of heat source and movement in a room.

• Based on area activeness, flap will adjust its position automatically.
• The human activity sensor is influenced by the location of the indoor unit, the movement speed of human/non-human activity, temperature range, etc.
• The human activity sensor may mistakenly detect non-human activity and source of heat, such as pets, or may not detect the human activity or source of heat if the person stays motionless.
• Do not place large objects near the sensor and keep away heating units or humidifier from the sensor’s detections area.

The sunlight sensor detects changes in sunlight intensity in the room. It reduces the waste of energy under less sunlight conditions.

5 Features

1. Temperature wave
   
   Rhythmic temperaturecontrolled pattern to save energy without sacrificing comfort.
2. Area search
   
3. Activity detection
   
4. Absence detection
   
   Human activity sensor detects presence/absence of human beings and the movement speed of human activities minimising the required amount of energy.
5. Sunlight detection
   
   Adjusts power to changes in sunlight intensity.
