1. One end of the control wire of the wired remote controller is connected to main board in the electric
box of indoor unit; it should be tightened by wire clamps, while the other end should be connected to
the wired controller. The special control wire be used between the indoor unit and wired remote
controller, of which the length is 8 meters.
2. The material to be adopted for the control wire should be metallic substance. The wired controller
could not be disassembled and the control wire to be used for the wired controller should not be
changed by users optionally. The installation and maintenance should be carried out by the installer.
3. Firstly select an installation position. According to the size of the control wire for the wired remote
controller, leave a recess or an embedded wire hole to bury the communication line.
4. If the control wire between the wired remote controller and the indoor unit is surface-mounted, use 1#
metallic pipe and make matching recess in the wall (refer to Fig. 30); If concealed installation is
adopted, 1# metallic pipe can be used (Refer to Fig. 31).
5. No matter if surface mounting or concealed mounting is selected, it is required to drill 2 holes (in the
same level) between which the distance shall be the same as the distance (60mm) of installation
holes in the bottom plate of the wired controller. Then insert a wood plug into each hole, fix the
bottom plate of the wire controller to the way through these two holes, plug the control wire onto the
