OPERATION
Once installed and the Thermostat Installer Setup
Number 0340 is set to 3, the remote inside temperature
is displayed on the Thermostat Home Screen as the
Inside Temperature. See Fig. 4.

Fig. 4. Inside Temperature Reading on
TH8000 Series Thermostat.
The C7189 Wall Mount Temperature Sensor converts
room temperature to a resistance that the thermostat can
interpret.
The C7189 has a negative temperature coefficient
(NTC), which means that resistance decreases as the
temperature increases. See Table 1.
The C7189 can be used to provide one remote sensor
input (see Fig. 2) or as a temperature averaging network
with multiple C7189 Sensors connected, as shown in Fig.
3.
CHECKOUT
For best results, allow C7189 Wall Mount Temperature
Sensor to absorb the air moving through the room for a
minimum of twenty minutes before taking a resistance
measurement.
With an accurate thermometer (±1°F [0.5°C]) measure
the temperature at the sensor location, allowing time for
the thermometer to stabilize before reading.
To verify sensor resistance, remove one wire from one of
C7189 wiring terminals. Use an ohmmeter to measure
the resistance across the sensor. Then verify the sensor
accuracy with the temperature/resistance in Table 1.
CALIBRATION
The C7189 Wall Mount Temperature Sensor is calibrated at the
factory and cannot be recalibrated in the field.
