Central Controller - Carrier 40WAU Series Installation And Maintenance Instructions Manual

Step 6 -- Position and Connect Controller
Controllers are ordered separately.
Wired controllers should be installed in a position that
maintains 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 window 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.
WIRELESS REMOTE CONTROLLER -- Before installa-
tion, operate the remote controller to determine the appropriate
location for reception range. Be sure the remote controller is at
least 3.25 ft away from electronic equipment such as a televi-
sion or stereo system to avoid cross-interference or distur-
bance. Avoid direct sunlight exposure or heating sources. Use
proper mounting screws and controller bracket to mount the
controller holder on the wall (see Fig 13). For setup instruc-
tions, refer to the controller installation manual.
