- Please make sure to leave no gaps on the top, bottom, left or right
sides between the remote controller and backplate.
- Before assembly with the backplate, arrange the Cable not to
interfere with circuit parts.
Remove remote controller by inserting a
screwdriver into the lower separating holes and
twisting to release the controller from backplate.
- There are two separating holes. Please individually separate one
at a time.
- Please be careful not to damage the inside
components when separating.
4. Please refer to the following directions when connecting the indoor unit and the
wired remote controller together.
1) Please connect the cables as shown in the figure below when connecting the plug type cable from the
indoor unit’s C/BOX and the housing type of the extension cable.
2) When connecting Terminal Blocks of the indoor C/BOX and the wired remote controller with the extension
cable, refer to the steps below.
①
Remove the screw on the cable which is fastened to the wired remote controller’s Terminal Block by
loosening with a screw driver.
②
Remove the housing of the provided 32ft extension cable with a cutting nipper and peel it as shown in the
figure below. (when purchasing the extension cable at the site directly, please peel it as shown in the figure
below.)
Please check if the connectors are connected properly.

5. Please use an extension cable if the distance between the wired remote controller
and the indoor unit is longer than 32ft(10 m).
③
Make sure each wire is securely fastened under each screw terminal and the wires are not in contact with
each other.
④
Please connect the Terminal blocks of indoor unit’s C/BOX and wired remote controller by referring to the
images and contents shown below.
Connect the yellow(signal) part of the wired remote controller’s terminal block and the ‘YL’ part of the indoor
unit’s terminal block.
Connect the red(12V) part of the wired remote controller’s terminal block and the ‘RD’ part of the indoor
unit’s terminal block.
Connect the black(GND) part of the wired remote controller’s terminal block and the ‘BK’ part of the indoor
unit’s terminal block.
In case of loosened screws or insufficient contact between the terminal and the wire, remote controller
may not function properly.
When the power is off on the remote controller, check the connection between the remote controller and
Terminal Block.
Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will
strip the head and make proper tightening impossible.
Over-tightening the terminal screws may break wires and terminal block structure.
<Remote controller> <Indoor Terminal Block>
• Installation work must be performed in accordance with the national wiring standards and local by
authorized personnel only.
• Installations must comply with the applicable local/national or international standards.
• AWG#22, 3 core shielded is recommended when using the large hole in the center of the back plate.
• AWG#24, 3 core shielded is recommended when using the side or top knock-out of the back plate.
CAUTION
When installing the wired remote controller, do not bury it in the wall.
(It can cause damage in the temperature sensor.)
Do not install the cable to be 164ft(50 m) or longer. (It can cause communication error.)

Remote controller installation
Since the room temperature sensor is in the remote controller, the remote controller box
should be installed in a place away from direct sunlight, high humidity and direct supply of
cold air to maintain proper space temperature. Install the remote controller about 5ft(1.5m)
above the floor in an area with good air circulation at an average temperature.
Do not install the remote controller where it can be affected by:
- Drafts, or dead spots behind doors and in corners.
- Hot or cold air from ducts.
- Radiant heat from sun or appliances.
- Concealed pipes and chimneys.
- Uncontrolled areas such as an outside wall behind the remote controller.
- This remote controller is equipped with LCD display. For proper display of the remote
controller LCD's, the remote controller should be installed properly as shown in Fig.1.
(The standard height is 4~5 ft (1.2~1.5 m) from floor level.)
