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.
WIRED REMOTE CONTROLLER (PROGRAMMA-
BLE) — To connect a programmable wired remote controller
(thermostat) to the indoor unit, use 4-core shielded cable and
4-pin connector from electrical box of indoor unit (see Fig. 9).
For setup instructions, refer to the controller installation
manual.
