Carrier 50XZ Thermistor
A very basic thermistor is a specific kind of resistor that has a fluctuating resistance that fluctuates depending on the amount of, or lack thereof, heat. They can tell the HVAC system when a temperature reaches a certain point. The heating and cooling system needs to know the temperature in a few critical areas to do its job correctly.
