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.
hIn case of loosened screws or insufficient contact between the terminal and the wire, remote controller
may not function properly.
hWhen the power is off on the remote controller, check the connection between the remote controller and
Terminal Block.
hUse an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will
strip the head and make proper tightening impossible.
hOver-tightening the terminal screws may break wires and terminal block structure.

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. 2.
(The standard height is 4ft~5ft(1.2m~1.5m) from floor level.)
