P.I.D. Control:
Proportional, integral, derivative control ( P.I.D.) is a temperature control algorithm used
in high-end temperature controllers. The controller causes the process to attain the desired
temperature by turning the process on or off. The process may be a heater or refrigerator. As
the process temperature approaches the setpoint temperature the hot or cold process will be
pulsed to reduce the corrective measures and minimize overshooting. The controller provides
a visual representation of the process status through LED indicators. An indicator may be lit
continuously, blink or shut off entirely to indicate that the process is on, being pulsed, or off,
respectively.
