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.
Modify Key: Press to view and change setpoint.
Decrease Key: Press in conjunction with Modify Key in order to decrease
setpoint.
Increase Key: Press in conjunction with Modify Key in order to increase
setpoint.
