T7047C,G ELECTRONIC THERMOSTATS AND REMOTE SPACE SENSORS
Location
Locate the thermostat or remote sensor about 5 ft (1.5m)
above the floor on an inside wall where it is affected by
freely circulating air at average room temperatures.
Mounting
1. Loosen the cover locking screw and remove the
thermostat cover.
2. Run wire to the selected location; thread wire
through the semicircular hole in the thermostat; and
make connections to the T7047 (see the
Wiring section).
3. Four mounting screws are provided, two self-
tapping type for wall mounting and two for outlet
box mounting. Select the proper screws for the
application.
4. If air drafts occur through the wall opening,
eliminate with suitable material.
5. Fasten the T7047 on the wall or outlet box with
screws through the thermostat mounting holes. See
Fig. 2.
NOTE: Connect sensor wires to T-T terminals on
the thermostat cover assembly.

IMPORTANT
• All wiring must agree with applicable codes, ordi-
nances and regulations.
• To avoid electrical interference, which can cause
erratic performance, keep wiring runs as short as
possible and do not run thermostat wires adja-
cent to the line voltage electrical
distribution systems.
• Use shielded cable (Belden type 8762 or
equivalent for 2-wire and Belden type 8772 or
equivalent for 3-wire).
• The cable shield must be grounded only at the
controlled equipment case.
