Where t is the temperature in °C and R is the resistance in Ω. Any coefficients that are
not used must be set to 0.

Thermistor function selection.
Select the thermistor type. Types available: R(T), 2.252 kΩ, 5 kΩ, and 10 kΩ.
Set up the channel for a 2-wire measurement connection. See “Sense Input Configuration” on
page 3-6.
Input a custom alpha-numeric label to help identify the channel (optional).
Set an alarm for this channel (optional). See “HI and LO Channel Alarms” on page 3-31.
