Temperature Sensor Accuracy
The DWM is furnished with a 20kΩ NTC temperature sensor
that follows a specific temperature-resistance curve. See Fig.
1. Honeywell controllers used with the DWM employ an
algorithm providing readings close to the actual temperature.
Table 2 summarizes the DWM sensor accuracy for normal
operating temperatures. Across the range of 43 to 104°F (6 to
40°C), the accuracy is better than ±0.75°F (±0.42°C).
