Configuring analog inputs to measure temperature with a thermistor
The FMS-2000C controller includes two dedicated thermistor inputs for measuring and monitoring resistive temperature sensors, or
thermistors. Once you have configured the controller for temperature using the thermistors, you can adjust the temperature setpoint on
the home screen by tapping the temperature icon. You can also set a comfort range to limit how many degrees the temperature can be
adjusted above or below the setpoint. After you have completed the configuration of the analog input, configure the analog output for
temperature. See
Configuring the analog output for temperature control
for more information.
