T7047C,G 

Electronic Thermostats 

and Remote Space Sensors

APPLICATION

The T7047C,G Electronic Thermostats and Remote 
Space Sensors are used in Series 70 Control Systems 
to provide modulating space temperature control.

SPECIFICATIONS

Models:

T7047C: 2-wire remote sensor for use with control 

systems such as the T7100, T7300, W927, W960, 
and W973.

T7047G: 2-wire remote sensor without internal 

adjustment means, requires remote setpoint device 
such as T7100, T7300, S963B, 7067B or T7080B.

Dimensions: 

See Fig. 1.

Temperature Sensor: 

Thermistor-resistor element.

Sensor Resistance:

For the following negative temperature coefficient (NTC) 

devices, resistance decreases as temperature 
increases (Fig. 8 and 9):
T7047C: 1420 ohms nominal at 75°F (24°C); 

resistance changes 15 ohms for each 1°F (0.6°C) 
temperature change.

T7047G: 710 ohms nominal at 75°F (24°C); 

resistance changes 7.5 ohms for each 1°F (0.6°C) 
temperature change.

Mounting: 

Mounts on wall or 2 x 4 in. vertical outlet box 

with screws provided.

Accessories:

209649A Universal Cover Plate (taupe); 

5-3/4 x 7-3/8 in. (146 x 187 mm).

209650A Universal Cover Plate (premier white); 

5-3/4 x 7-3/8 in. (146 x 187 mm).
