2.2 Installation Requirements
Installation Location 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 affected.
- 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).
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))
For proper installation, follow the steps below:
- Before installation, cut off the power supply of the indoor unit.
- 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.
- Place the mounting plate of the wired controller on the wall, and use the M4x25 screws to attach the mounting plate on the wall.
- 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.
- Secure the panel of the wired controller to the mounting plate, and installation is complete.

pollution level and the accumulative operating time. After setting, when the
washing time is reached, the “CLEAN” icon will flash. If you press the up or
down arrow button to adjust the level followed by the “SWING/ENTER” button,
the accumulative time will not reset. If the time after adjustment is larger
than the current accumulative time, the “CLEAN” icon will stop flashing. If
the time after adjustment is less than the current accumulative time, the
“CLEAN” icon will continue to flash. The only method for cancelling the remind
function is to press “FUNCTION” to switch to the “CLEAN” icon, set the timer
area to “00”, and press the “SWING/ENTER” button. After this is completed, the
accumulative time of the filter washing reminder is reset.

4.9 Setting of Other Functions
Setting of Energy-Saving Function:
Under OFF status, press “TIMER” and the up arrow button simultaneously for
5 seconds to enter the energy-saving setting. The “SAVE” icon and cooling icon
are displayed, the “SAVE” icon flashes, and the temperature area displays the
upper limit and lower limit temperature. Press the up or down arrow button to
set the limit temperature. The setting range is 61°F~86°F (16°C~86°C).

Press “SWING/ENTER” at any time to save the setting temperature and the energy-saving status of different modes, then start up the energy-saving function.
After the energy-saving function is activated, under OFF status, press “TIMER” and the up arrow button simultaneously for 5 seconds again, and the function will be canceled.
Setting of Low-Temperature Dry Function:
Under dry mode, when the setting temperature is 61°F (16°C), press the down
arrow button twice. The setting temperature lowers to 54°F (12°C) and the unit
enters into low-temperature dry function.
When the low-temperature dry function is turned on, immediately press the up arrow button or switch the mode to quit the function.
Setting of Child-Lock Function:
Without error, under ON or OFF status, press the up and down arrow buttons
simultaneously for 5 seconds to enter the child-lock function. The LCD screen
will display “ “. Press the up and down arrow buttons simultaneously again for
5 seconds to quit the child-lock function.
Under child-lock status, no response will occur from pressing any button. The unit will remember to enter back into child-lock status after power failure.
Setting of Memory Function:
Under OFF status, press “MODE” and the up arrow button simultaneously for 5
seconds to turn on or turn off the memory function. When the memory function
is properly set, “MEMORY” will be displayed on the screen.
If the memory function has not been set, if a power failure occurs, the unit will return to off status. If the memory function is set, the unit will resume its previous operating status after power failure.
Switching between Fahrenheit and Celsius:
Under OFF status, press “MODE” and the down arrow button simultaneously for
5 seconds. The display will switch between Fahrenheit and Celsius.
Inquiry of Ambient Temperature:
Under OFF or ON status, press and hold the “SWING/ENTER” button for five
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.
5 TROUBLESHOOTING
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 off 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 flowing 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 finished, 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 first 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 off the unit and seek professional assistance.
