Step 6 -- Position and Connect Controller
Wired controllers should be installed in a position that main-
tains good temperature control:
• Position the thermostat approximately 48 in. above floor
level.
• Do not position thermostat where it can be directly
affected by the unit's discharge airstream.
• Avoid external walls and drafts from windows and doors.
• Avoid positioning near shelves and curtains as these
restrict air movement.
• Avoid heat sources such as direct sunlight, heaters, dim-
mer switches, and other electrical devices.
REMOTE WIRELESS CONTROLLER -- Before installa-
tion, operate the remote controller to determine the appropriate
location for reception range. Make sure the remote controller is
a minimum of 3.25 ft away from any electronic equipment
such as a television or stereo system to avoid cross interference
or disturbance. Avoid direct sunlight exposure or heating
sources. Use proper mounting screws and controller bracket to
mount the controller on the wall (see Fig. 11). For setup in-
structions, refer to the controller installation manual.
