Example: Cooling
With the infrared sensor, the air conditioner can detect the activity level in a room and adjust the temperature
and humidity automatically, thus achieving the purpose of energy saving.

• The energy saving effect can be achieved only after the energy-saving temperature control function keeps working
for more than 2 hours.
In the energy-saving temperature-control mode, the energy consumption saved by the air conditioner varies with
the activity level.

The infrared sensor detects changes to the infrared generated by human bodies. Therefore, the accuracy of infrared
sensor may be affected negatively in the following cases:
·
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.

The tracing function (Page 20) can further reduce the energy consumption.
After detecting that the person leaves the room for 30 minutes, the air conditioner turns to the energy-saving modes
according to the settings in the remote controller as shown in the right table, but the preset temperature and humidity
in the remote controller remain unchanged.
When the air conditioner works in powerful operation, setting the energy-saving mode will cancel the powerful operation.
