SPECIFICATIONS
Dimensions (H W D): 2 1-9/16 3/4 in.
(56 46 19.3 mm).
Construction: Two-piece construction (a cover and an
internally wired sub-base). Field wiring 16 to 22 AWG (1.5 to
0.34 mm
2
) connects to a terminal block.
Operating Temperature: 43...104°F / 6...40°C.
Shipping Temperature: -40...150°F / -40...65°C.
Relative Humidity: 5% to 95% non-condensing.
Accuracy: t = 0.3 K +1% |t - 25 °C| (t in °C)
Safety: terminal box
Protection standard: IP30
Approvals: CE, EAC
BEFORE MOUNTING
All wiring must comply with local electrical codes and
ordinances or as specified on installation wiring diagrams.
Removing the Cover
The cover of the space-temperature sensor can be easily
popped off by applying pressure simultaneous pressure to the
right and left sides at the top and bottom (see Fig. 2).
Fig. 2. Removing the cover
Space-temperature sensor wiring can be sized from 16 to 22
AWG (1.5 to 0.34 mm
2
), depending on the application. The
maximum length of wire from a device to the space-
temperature sensor is 1000 ft (305 m). Twisted-pair wire is
recommended for wire runs longer than 100 ft (30.5 m).
Wire Insertion
After removing the cover, the wires can be easily inserted into
the terminal block as shown in Fig. 3. The terminals are
insensitive to polarity.

Fig. 3. Wire insertion
To facilitate wire insertion, it is possible to temporarily remove
the terminal block from the housing. After wire insertion,
however, the terminal block should be snapped back into
place.
MOUNTING
Mount the T7470A1009 on an inside wall approx. 54 in.
(1.3 m) from the floor (or in the specified location) to allow
exposure to the average zone temperature.
Maintain a mounting clearance of approx. 4 in. (10 cm) to
both sides of the space-temperature sensor in order to allow
free airflow.
Do not mount the space-temperature sensor on an outside
wall, on a wall containing water pipes, or near air ducts. Avoid
locations exposed to discharge air from registers or radiation
from lights, appliances, or the sun.
Keep wiring at least one ft (305 mm) away from large induc-
tive loads such as motors, line starters, lighting ballasts, and
large power distribution panels. Run space-temperature
sensor wiring separately from 50 Vac or greater power wiring.
The T7470A1009 can be mounted directly onto walls (see
Fig. 4 for dimensions and drilling template), in which case the
type of screws appropriate to the wall material should be
used.
