WIRED CONTROLLER INSTALLATION PRECAUTION

1. This manual provides the wired controller installation method.
   Refer to the wiring diagram in this installation manual to wire the wired controller with the indoor unit.

2. The wired controller works in a low voltage loop circuit. Do not connect directly to 208/230V and 460V. Do not wire this kind of wire into a loop. Wiring clearance between the configured tubes should range 11.81−19.69 inches (30−50 cm) or above.

3. The shielded wire of the wired controller must be properly grounded.

4. Upon finishing the wired controller connection, do not employ tramegger to detect the insulation.

INSTALLATION METHOD

1. Wired Remote Controller Dimensions

2. Wiring Connection Diagram

3. Wiring figure ● Connect the female joint of the wires group from the mainboard with the male joint of the connective wires group. (See Fig.3-3(A))
   ● Connect the other side of the connective wires group with the male joint of the wires group leads from the wired controller. (See Fig.3-3(A))● Install the Adapter Board and the Display Board on the High Wall (See the Appendix for instructions).
   ● Connect the female joint of the wires group from the adapter board with the male joint of the connective wires group. Next, connect the other side of the adapter board with the display board.
   ● (See Fig.3-3(B)) Connect the other side of the connective wires group with the male joint of the wires group leads from the wired controller. (See Fig.3-3(B))

4. Wired controller upper part Remove
   Insert a flat screwdriver into the slots in the lower part of the wired controller (2 places).
   Remove the upper part of the wire controller (Fig.3-4)
   NOTE: The PCB is mounted in the upper part of the wired controller. Be careful not to damage the board with the screwdriver.

5. Fasten the wired controller back plate
   For surface mounting, fasten the back plate on the wall with the 3 screws (ST3.9×25) and plugs. (Fig.3-5) ● For switch box mounting, fasten the back plate on the switch box with 2 screws (M4x25) and fasten it on the wall with 1 screw (ST3.9×25). (Fig.3-6) NOTE: Place on a flat surface. Be careful not to distort the wired controller’s back plate by over−tightening the mounting screws.

6. Battery installation ● Place the battery in the unit and ensure the positive side of the battery is in accordance with the polarity markings.(See Fig.3-7)
   ● Set the correct time before operating. Batteries in the wired controller can maintain the correct time during a power failure. When the power is restored and the displayed time is not correct, replace the battery.

7. Wire the indoor unit
   There are three methods:
   1. from the rear;
   2. from the bottom;
   3. from the top; 4. Notch the part for the wiring to pass through with a nipper tool.
   NOTE: DO NOT allow water to enter the remote control.
   Use the trap and putty to seal the wires.

8. Reattach the wired controller’s upper part
   While adjusting and mounting the upper case, avoid clamping the wiring during installation. (Fig 3-9) IMPORTANT: All the pictures in this manual are for illustration purposes only. Your wired controller may differ slightly.

Using the wired controller to set external static pressure (some air conditioners) .

• You can use the unit’s automatic airflow adjustment function to set external static pressure.
• Automatic airflow adjustment is the volume of blow-off air that has been automatically adjusted to the quantity rated.

1. Make sure the test run is done with a dry coil. If the coil is not dry, run the unit for 2 hours in FAN ONLY mode to dry the coil.

2. Check that both power supply wiring and duct installation have been completed Check that any closing dampers are open.
   Check that the air filter is properly attached to the air suction side passage of the unit.

3. Set the parameters for automatic airflow adjustment. When the air conditioning unit is off, perform the follwoing steps:
   – Press“Copy” long.
   – Press “+” or “-” to select the AF.
   – Press “Confirm”. The air conditioning unit will then start the fan for airflow automatic adjustment.

DO NOT adjust the dampers when automatic airflow adjustment is active.
After 3 to 6 minutes, the air conditioning unit stops operating once automatic airflow adjustment has finished.
Using the wired controller to set airflow rate (some air conditioners).
When the air conditioning unit is off, perform the follwoing steps:

• Press“Copy” long.

• Press “+” or “-” to select the SP.

• Press “Confirm” to set the airflow.
  0 means a stable airflow volume, 1 to 4 means an increase in airflow volume.
