2.3 Installation & Disassembly
Select the correct signal wire of the wired controller that meets the following requirements:
• 2-Core Signal Wire
• Diameter: at least .0008in (.75mm)
• Length: less than 98.4ft (30m) (Recommended length is 26.25ft (8m))

2.2 Installation Requirements
1. Do not install the wired controller in a location that is wet or likely to become wet.
2. Do not install the wired controller near high-temperature objects or under direct sunlight.
3. Do not install the wired controller in a position facing a window, as it can lead to interference with
a nearby remote controller of the same model, resulting in possible malfunction.
4. Before installing, disconnect the power supply inside the wall. Do not install while power is
connected.
5. In order to avoid malfunction due to electromagnetic interference and other causes, take note of
the following:
• Ensure that the interface of the communication wire is correct, otherwise communication
cannot occur.
• Ensure the signal wire of the wired controller is separated from the power cord and indoor and
outdoor connecting wire. The shortest distance should be at least 8in (20cm), or communication
will be aected.
• If the unit is installed in a location likely impacted by an electromagnetic interface, the signal
wire of the wired controller should be made of STP (shielded twisted pair).
6. The wired controller should only be installed indoors, with a working temperature range of
32°F~122°F (0°C~50°C).

For proper installation, follow the steps below:
1. Before installation, cut o the power supply of the indoor unit.
2. Pull out the 2-core STP from inside the installing hole in the wall. Thread the wire through the connecting
hole in the back of the mounting plate of the wired controller.
3. Place the mounting plate of the wired controller on the wall, and use the M4x25 screws to attach the
mounting plate on the wall.
4. Connect the 2-core STP with the two wiring terminals on the back of the wired controller respectively, and
tighten the screw. (There is no polarity for these two wiring terminals. They should not be connected to high
voltage.
5. Secure the panel of the wired controller to the mounting plate, and installation is complete.
For disassembly, follow the steps demonstrated in the gure below:

Under OFF or ON status, press and hold the “SWING/ENTER” button for ve seconds to enter into the ambient
temperature inquiry interface. The timer area will display the ambient temperature type 01 (outdoor ambient
temperature) or 02 (indoor ambient temperature), and the ambient temperature area displays the corresponding
ambient temperature of corresponding type.
Press any button other than “MODE”, or when the unit receives remote control signal, and the controller will quit the
inquiry status. If there is no activity for 20 seconds, the controller will quit automatically.
NOTE:
• When the outdoor temperature sensor detects the same temperature for 12 hours, it will shield the display of
the outdoor temperature sensor.
• When the outdoor unit enters into low power consumption mode, the wired controller cannot check for a
valid outdoor ambient temperature.

Setting of Auto Clean Function:
Under OFF status, press and hold the “TIMER” and “MODE” buttons simultaneously for 5 seconds to turn on or turn
o the internal cleaning function.
When the internal cleaning function is turned on, the temperature display area will show “CL”.
During the self-cleaning process of the evaporator, the unit will perform fast cooling or fast heating. It may emit some
noise, which is the sound of owing liquid, thermal expansion, or cold shrinkage. The air conditioner may blow cool
or warm air, which is normal and to be expected.
During cleaning, ensure the room is well-ventilated to avoid any alteration to the environment’s comfort level.
NOTE:
• The self-cleaning function can only work under normal ambient temperature. If the room is dusty, it is
recommended to use the self-cleaning function once a month. If not, it is recommended to use the self-
cleaning function once every three months.
• It isn’t required to remain with the unit once the self-cleaning function is turned on. When self-cleaning is
nished, the unit will automatically enter standby mode.
• This function is only applicable for some models.
5.1 Error Code Display
When an error occurs in the system, the temperature area of the LCD screen will display an error code. When
multiple errors occur simultaneously, each error code will be cycled through circularly on the screen. If the controller
is connected to multiple systems, when an error occurs in one system, the rst section of the error code on the
screen refers to the system number. If there is only one system, no system number will be displayed.
When an error occurs, turn o the unit and seek professional assistance.
