4.2 Installation Location and Installation Requirements
(1). Do not install the wired controller in the damp place or under direct sunlight.
(2). Do not install the wired controller close to the hi-temperature object or place where the
wired controller is likely to suffer water spray.
(3). Do not install the wired controller directly opposite to the window so as to avoid improper
operation caused by the interference of the neighbor’s same model wired controller.
(4). Please cut off the power supply of wires embedded in the wall. No operation is allowed with
electricity.
(5). To avoid abnormal operation caused by electromagnetic interference or other causes,
please take notice of the following statements during wiring.
① .
Be sure the communication line is wired into the correct port, otherwise it would result in
communication fault.
② .
The communication line (wired controller) and power line must be separated with the
minimal distance of 20cm, otherwise it would result in communication fault.
③ .
Suppose that the air conditioner is installed where likely to suffer electromagnetic
interference, the communication line of the wired controller must be shielded twisted pair.
4.3 How to Install the Wired Controller
First of all, the selection and connecting method of the communication line is shown as follows:
(1). Select appropriate communication line of the wired controller: 2-core signal line (wire
size≥0.75mm
2
, length<30m, recommended length: 8m).
(2). After the indoor unit is de-energized, fix the communication line on the indoor terminal
board by screws.
Then, the specific installation steps is shown in the Fig.27:
