Wiring Principle Sketch

Wiring figure:

1. Connect two terminals of embedded 4-core shielding wire with the switching wires of wired remote controller and signal receiving board. Make sure the sequence of 4 terminals (A/B/C/D) should correspond to the wire sequence of signal switching wires (A/B/C/D).
   

2. If embedded 4-core shielding wire cannot go through the wired controller, it can use signal switching for connection and make sure the wires are reliable and firm. The tightening torque range of the screw is0.8~1.2N .m (8~12 kgf . cm).
   

Back Cover Installation

1. Use straight head screwdriver to insert into the buckling position in the bottom of a wired controller, and spin the screwdriver to take down the back cover. (Pay attention to spinning direction, if not you maybe damage the back cover.)
   

2. Use three GB950-86 M4X20 screws to directly install the back cover on the wall.
   

3. Use two M4X25 GB823-88screws to install the back cover on the 86 electrician box, and use one GB950-86 M4X20 screw for fixing the wall.
   

4. Adjust the length of two plastic screw bars in the accessory to be the standard length from the electrical box screw bar to the wall. Make sure when install the screw bar to the electrical box screw bar, make it as flat as the wall.
   

Notes :

1. Use cross head screws to fix the wired controller bottom cover in the electric control box through the screw bar. Make sure the wired controller bottom cover is on the same level after installation, and then install the wired controller back to the bottom cover.
2. Over fasten the screw will lead to deformation of the back cover.

Wiring

1. Wiring, three outlet positions
   

2. Shielded wiring
   

3. Avoid water enters into the wired controller, use trap and putty to seal the connectors of wires during wiring installation.
   When under installation, reserve a certain length of the connecting wire for convenient to take down the wired controller while during maintenance.
   

Front Cover Installation

1. After adjusting the front cover and then buckle the front cover; avoid clamping the communication switching wire during installation.
2. Correct install the back cover and firmly buckle the front cover and back cover, if not you maybe make the front cover drop off.
   

Wired Controller Initial Parameters Setting

1. Change the related functions of the controller through adjusting the initial parameters, details refer to table 1
2. The wired controller initial parameter includes two codes “XY”, the first code “X” means function class, and the second code “Y” means the detailed configuration of this function.
3. Setting method:
4. Simultaneously press “Mode” and “Fan” button of the wired controller for 5 seconds to enter the parameter setting state;
5. The value of this first code “X” is “0”; press the temperature setting button UP and DOWN to adjust the second code value;
6. After setting the second code value, press 26/OK button to switch the first code to the next value;
7. When the first code value is “6”, press 26/OK button again to exit the parameters setting.
