Step 6 - Position And Connect Controller; Wireless Remote Controller; Wired Remote Controller; Wired Remote Controller (Non-Programmable) - Carrier 40WAW007 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. Avoid direct sunlight exposure or
heating sources. Use proper mounting screws and controller
bracket to mount the controller on the wall (see Fig. 9). For set-
up instructions, refer to the controller installation manual.
