6.6 Thermostat Installation and Wiring
NOTICE
Risk of improper thermostat installation. Can cause unit malfunction.
• Installation work must be performed in accordance with the national wiring standards and local
code by authorized personnel only.
• If local electric and building code requires plenum(CMP) cable, use an enclosed, non-
combustible conduit (metal raceway) or FT-6 rated or above cable.
• When using back cable-entry, AWG#22, 3 core shielded wire is recommended.
• When using top or right-side cable entry, AWG#24, 3 core shielded wire is recommended.
• Do not bury the thermostat in the wall. This can damage the temperature sensor.
• Do not install a cable 164 ft (50 m) or longer. This can cause communication errors.
Because the room-temperature sensor is in the thermostat, it should be installed in a place away from
direct sunlight, high humidity, and direct supply of cold air to maintain proper temperature of the space.
Install the thermostat about 5 ft. (1.5 m) above the floor in an area with good air circulation at an average
temperature,
Figure 6-14 .
Do not install the thermostat where it can be affected by the following:
• Drafts or dead spots behind doors and in corners.
• Hot or cold air from ducts.
• Radiant heat from sun or appliances.
• Concealed pipes or chimneys.
• Uncontrolled areas such as on an outside wall.
The thermostat is equipped with an LCD display and should be installed at the recommended height for
proper view of the display.

NOTE
If the distance between the thermostat and the indoor unit is longer than 32 ft
(10 m), use an extension cable.
