SPECIFICATIONS

IMPORTANT
The specifications given in this publication do
not include normal manufacturing tolerances.
Therefore, this unit may not exactly match the
listed specifications. This product is tested and
calibrated under closely controlled conditions,
and some minor differences in performance can
be expected if those conditions are changed.
Models:
T7047C: 2-wire remote sensor with no internal
adjustment means (requires remote setpoint device
such as S963B, T7067B, and T7080B).
T7047C1009: 2-wire remote sensor for use with
control systems such as M7044 and M7045
Motors.
T7047C1025: 2-wire remote sensor for use with control
systems such as the W927, W960, and W973.
T7047C1082: 2-wire remote sensor for use with
T7080B Transmitter in W7080 Multizone Control
System.
T7047G: 2-wire remote sensor with no internal
adjustment means (requires remote setpoint device
such as S963B, T7067B or T7080B).
T7047H: Thin-film, platinum 1K (at 0°C) temperature
sensor only. For use with the Excel 80/100/500/600
Controllers.
Dimensions: See Fig. 1.
Mounting: Mounts on wall or 2 x 4 in. vertical outlet box
with screws provided.
Temperature Sensor: Thermistor-resistor element.
Cover Thermometer (available on most models):
Element: Bimetal.
Range: 55 to 95°F (13 to 35°C).

  • Page 7: Operation And Checkout

    OPERATION AND CHECKOUT Operation The T7047C,G Remote Sensor control element is a negative temperature coefficient (NTC) thermistor. As the room temperature increases, the resistance of the thermistor decreases. The T7047H Remote Sensor control element is a positive temperature coefficient (PTC) thermistor. As the room temperature increases, the resistance of the thermistor increases.
