Description
The Honeywell 31117481-501 Ref Probe, commonly known as a temperature probe, is an essential component in many HVAC systems, including freezers, dehumidifiers, and furnaces. It functions by taking a measurement of the nearby air or refrigerant temperature. The control unit of the system receives this information and uses it to control several operations, including compressor running, dehumidification cycles, and furnace heating stages. The probe is often composed of a thermistor, a type of temperature-sensitive resistor that modifies its electrical resistance in response to changes in the surrounding air temperature. The control unit then interprets this change in resistance to calculate the actual temperature.
