How Does a Commercial Thermostat SPT Work?
The first part of an SPT’s functioning takes place in the thermistor. The thermistor reacts to changes in temperature by altering the amount of resistance it produces when subjected to an electrical charge. This charge comes from the microcontroller, which reads this resistance and interprets it as the temperature readout on the front of the thermostat. The microcontroller responds to its programming if the temperature should ever rise above or drop below the thresholds programmed by the user. If the temperature should be too high, the microcontroller sends an electrical impulse through the circuit board to the air conditioning unit. It does the same for the heating unit if the temperature should drop too low. When the temperature has returned to lie within the threshold, the microcontroller stops the electrical impulse, stopping the heating or cooling units.
