Note to installation of wire controller:

1. This installation manual contains information about the procedure of installing Wired Remote Controller. Please refer to Indoor Unit Installation Manual for connecting between Wired Remote Controller and Indoor Unit.
2. Circuit of Wired Remote Controller is low voltage circuit. Never connect it with a standard 220V/380V circuit or put it into a same Wiring Tube with the circuit.
3. The shield cable must be connected stable to the ground, or transmission may fail.
4. Do not attempt to extend the shield cable by cutting, if it is necessary, use Terminal Connection Block to connect.
5. After finishing connection, do not use Megger to have the insulation check to the signal wire.

INSTALLATION PROCEDURE

1. Wired remote controller structure size figure

2. Wiring Principle Sketch:

3. Wiring figure

CAUTION

1. Connect two terminlas of embedded 4-core shielding wirewith the switching wires of wired remote cotnroller and signal receiving board. Make sure the sequenc of 4 terminals (A/B/C/D) should correspond to the wire sequence of signal switching wires (A/B/C/D). (Refer to Fig. 3)

2. If the embedded 4-core shielding wire can not go through the wired remote controller, it can use signal switching for connection (Refer to Fig.

3. make sure the wires are reliable and firm.

4. Back cover installation
   CAUTION
   

5. Use straight head screwdriver to insert into the buckling position in the bottom of wire controller, and spin the screwdriver to take down the back cover. (Pay attention to spinning direction, otherwise will damage the back cover!) (Fig.5)

6. Use three GB950-86 M4X20 screws to directly install the back cover on the wall. (Fig.6)

7. Use two M4X25 GB823-88screws to install the back cover on the 86 electrician box, and use one GB950-86 M4X20 screws for fixing on the wall. (Fig.7.1) Adjust the length of two plastic screw bars in the accessory to be 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. (Fig.7.2)

8. Use cross head screws to fix the wire controller bottom cover in the electric control box through the screw bar. Make sure the wire controller bottom over is on the same level after installation, and then install the wire controller back to the bottom cover.

9. Over fasten the screw will lead to deformation of back cover.

10. Wiring
    CAUTION
    Avoid the water enter into the wired remote controller, use trap and putty to seal the connectors of wires during wiring installation. (Fig.10)
    When under installation, reserve certain length of the connecting wire for convenient to take down the wired remote controller while during maintenance.

11. Front cover installation
    CAUTION
    After adjusting the front cover and then buckle the front cover; avoid clamping the communication switching wire during installation. (Fig.11)
    Correct install the back cover and firmly buckle the front cover and back cover, otherwise will make the front cover drop off. (Fig. 12)

WIRED REMOTE CONTROLLER INITIAL PARAMETER SETTING

3. Setting method:
4. Simultaneously long press “Mode” and “Fan” button of the wired remote 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 and to adjust the second code value;
6. After setting the second code value, press button to switch the first code to the next value;
7. When the first code value is “6”, press button again to exit the parameters setting.
