COPILOT Operation

Human Sensing Function
1. “Follow” function: It can detect where a person is and adjust the swing flap accordingly and send air to the location of this person. If it detects people in two locations, the swing flap will blow alternatively between these two locations and stay at each location for 15s. If the appliance detects people in three or more locations, the left and right swing flaps will swing automatically. “Avoid” function: When the appliance detects a person in a location, it will adjust the swing flap to avoid such a location. If it detects people in three or more locations, the left and right swing flaps will swing automatically.
Note:

1. When there are people in several locations or a person frequently moves between several locations,if this person is in the in-between location or the crossing location, whether the appliance is in a “Follow” mode or an“Avoid” mode, the swing flap will swing automatically to send air to these locations.

2. Whether the setting is “Follow” or “Avoid”, it takes some time to adjust their direction after the appliance identifies the location of the people and the air direction will not change immediately.

3.  If the actual airflow cannot reach (or avoid) the location where a person is due to such factors as fan speed setting, temperature setting, ambient temperature difference and
   the layout of the room, pressing the left and right swing flaps can adjust the air direction and set the airflow direction manually.

4. Setting the health airflow when the human sensing (including follow/avoid) function is enabled will force exit from the human sensing (including follow/avoid) function.

5. Upper and lower swing flaps are not operational when the human sensing (including follow/avoid) function is enabled.

6. When the human sensing function is enabled, if the appliance cannot detect people for a long time (at least 20 minutes), it will automatically enter the power-saving mode. In the power-saving mode, the operating frequency will be reduced and the fan speed set at low. Once a person is detected, the appliance will exit from the power-saving mode.

7. When the human sensing function is enabled, the appliance will have a real-time detection of human movements and adjust the frequency and fan speed according to the movements. In the heating mode, if the movements are frequent, the frequency and fan speed will lower down; when the movements become less, the frequency and fan speed will rise but cannot exceed the setting values set by the remote controller.
