5.6.2 Position and Method of Installing Wired Remote Controller
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 a 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. 5-20); If concealed installation is adopted, 1# metallic pipe
can be used (Refer to Fig. 5-21).
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 control panel, and lastly install the panel of the wire
controller.( Refer to Fig. 5-4)
