C7189U REMOTE INDOOR SENSOR
CHECKOUT
For best results, allow the sensor to absorb the air
moving through the room for a minimum of twenty
minutes before taking a resistance measurement.
1. Use an accurate thermometer (+/-1ºF[0.5ºC]) mea-
sure the temperature at the sensor location.
2. Remove one wire from one of the sensor's wiring
terminals. Use an ohmmeter to measure the resis-
tance across the sensor. Verify the sensor accu-
racy with the temperature/resistance in Table 1.
CALIBRATION
The sensor is calibrated at the factory and cannot be
recalibrated in the field.
