Temperature Sensor Accuracy
The DWM is furnished with a 20k
Ω
NTC temperature
sensor that follows a specific temperature-resistance curve.
See Fig. 1. Honeywell controllers used with the DWM
employ an algorithm that provides 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).

NOTE:
If connected to Excel 10 UV Controller W7753, fan
output will not be shorted to ground on pressing
the BYPASS button; with every other Excel 10
Controller, it will be shorted.
See T7560A,B,C Installation Instructions (product
literature no.: EN1B-0146GE51) for configuration.

DWM Setpoint Adjustment
The relation between setpoint and resistance is given in
Table 5 and Table 6. Accuracy of resistance is:
•
±
5% in middle position, e.g. 5225
Ω
to 5775
Ω
•
±
10% in end position, e.g. 9450
Ω
to 11550
Ω
.
Setpoint accuracy: ± 0.2 K
