The independent control mode of the air deflector is set through the wire controller or the remote controller, and when the wire controller or the remote controller is set to be the independent control mode of the air deflector, the air deflector can enter the independent control mode. After the air deflectors enter the independent control mode, other related controls on the air deflectors are closed, and the corresponding air deflectors can be controlled respectively according to the positions of users. The four air deflectors have own numbers (for example, numbers 1-4), and a user can respectively control the air deflectors with the corresponding numbers (numbers 1-4) according to the position of the user, and control the number of the opened sections or the closing of the air deflectors.
The control mode of the air deflector human sensing is set through the line controller or the remote controller, and after the line controller or the remote controller is set to be the control mode of the air deflector human sensing, the air deflector can enter the human sensing control mode.
