Function

ENGLISH

• 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.

5. Please use an extension cable if the distance between the wired remote controller
and the indoor unit is longer than 32ft(10m).

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(50m) or longer. (It can cause communication error.)

Owner’s & Installation Manual 7

Installation instruction

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.)
