⚠
WARNING
• Installation must be performed by the distributor or qualified professionals.
• Installation by untrained individuals may result in improper setup, electric
shock, or fire.
• Always follow the instructions in this manual.
• Incorrect installation can cause electric shock or fire.
• Reinstallation must also be carried out by professionals.
• Do not uninstall the unit arbitrarily.
Uninstalling the unit without proper procedures may lead to malfunction,
heating issues, or risk of fire in the air conditioning system.
ℹ
NOTE
• Do not install the unit in areas where flammable gases may leak.
Accumulation of such gases around the wired controller may result in fire.
• Do not operate the unit with wet hands or allow water to enter the wired
controller. Doing so may cause electric shock.
• Ensure the wiring is compatible with the current rating of the controller.
Mismatched wiring may cause electrical leakage, overheating, or fire. Use
only the specified cable types for wiring. Do not apply excessive force to
terminals. Doing so may damage the wires, leading to overheating or fire.

Precautions for Installing the Wired Controller
1. This manual provides instructions for installing the wired controller.
A. Refer to the wiring diagram within this manual for correct connection
of the wired controller to the indoor unit.
2. The wired controller operates in a low-voltage circuit.
A. Do not connect or route high-voltage cables (e.g., 115V, 220V, 380V)
within this loop.
B. Ensure a minimum separation distance of 12–20 in. (or more) between
low-voltage and high-voltage wiring.
3. The shielded wire of the wired controller must be properly grounded.
4. After completing the wiring connection, do not use a megohmmeter
(insulation resistance tester) to test the insulation, as this may damage the
controller.

Note: The PCB (Printed Circuit Board) is located in the upper section of the
controller. Use caution when using a screwdriver to avoid damaging the board.
Fasten the Back Plate of the Wired Controller
• For exposed wall mounting:
- Use three screws (M3.5 × 25) and corresponding wall plugs to secure
the back plate directly to the wall surface.
- Refer to Fig. 3-3 for proper screw placement.
• For mounting on a standard 86 switch box:
- Use two M4 × 25 screws to secure the back plate to the switch box.
- Use an additional M4 × 25 screw to anchor the back plate to the wall
for added stability.
- Refer to Fig. 3-4 for guidance.

Note: Place the wired controller on a flat surface during installation. Avoid
overtightening the mounting screws, as it may distort/damage the back plate.
Battery Installation
Insert the battery into the designated battery compartment, ensuring the
positive (+) side of the battery aligns with the positive terminal in the
compartment (see Fig. 3-5).
Upon first-time use, set the correct time on the controller. The internal battery
allows the controller to retain the clock settings during power outages.
If, after power is restored, the displayed time is incorrect, it indicates that the
battery has failed and should be replaced.

Refer to Figures 3-6 and 3-7 for proper wiring layout.
• Connect the wired controller to the indoor unit using the designated
terminal port as shown in Fig. 3-6.
• Create a notch in the back plate or switch box to allow the wiring to pass
through. Use wire cutters/snippers for a clean and accurate cut (Fig. 3-7).

Connect the wire from the master control board of the indoor unit to the
connection cable. Then, connect the other end of the cable to the wired remote
controller, as shown in Fig. 3-8.
• Use a 4-conductor wire for communication.
• The connective wiring harness should include a magnetic ring to help
suppress electrical interference.
• Use shielded wire to reduce signal noise and ensure stable operation.
Note:
• Leave sufficient slack in the connective wire to allow for future maintenance or service.
• At the end of the shielded wire, there is a grounding lug. Ensure this lug is properly
connected to a reliable ground point to maintain electrical safety and signal integrity.
