ECO SENSOR OPERATION
The ECO sensor can detect the human activity level in a room and adjust the setting temperature automatically
to achieve energy saving.

• The energy saving is more effective after the ECO SENSOR OPERATION keeps working for more than
2 hours.
• In the ECO SENSOR OPERATION, the energy consumption saved by the air conditioner varies with the
activity level.
• Comfort airflow (direct airflow operation)(page 15) can further reduce the energy consumption.
• After detecting that the person leaves the room for 20 minutes, the air conditioner turns to the ECO modes
according to the settings in the remote controller as shown in the table below, but the preset temperature
in the remote controller remain unchanged.
• When the air conditioner works in powerful operation, setting the ECO mode will cancel the powerful operation.

The eco sensor detects changes to the infrared generated by human bodies. Therefore, the accuracy of eco sensor
may be affected negatively in the following cases:
• The activity level is very low (reading, watching TV, etc.) or human bodies are blocked by a screen, cabinet, or
glass board.
• The indoor temperature is very high and exceeds or approaches the human body temperature (when the
refrigeration just begins).
• The person wears thick clothes and turns his/her back to the air conditioner.
• Curtains or plant leaves swing due to pet movement or airflow.
By pressing the

HEATING, DEHUMIDIFYING or COOLING operations, the air
