PID Control
PID controllers are best suited for systems that may experience changing
heat loads. Proportional control is combined with Integral and Derivative
adjustments which allow the controller to automatically compensate for any
changes from the setpoint. You may have to experiment with the PID set-
tings to find out which are most suitable to your application.
To change or view any of the PID settings the controller must be operating.
To change or view the proportional band, press "1" and immediately, within
one second, press ENTER. The "percent of span" value will flash on the
Main display. Press ENTER to accept the value. To change the value press
CLEAR and then enter the desired value. Press ENTER to exit this mode.
To change or view the Integral, press "2" and and immediately, within one
second, press ENTER. The "repeats per minute" value will flash on the Main
display. Press ENTER to accept the value. To change the value press
CLEAR and then enter the desired value. Press ENTER to exit this mode.
To change or view the Derivative, press "3" and and immediately, within one
second, press ENTER. The "minutes" value will flash on the screen. Press
ENTER to accept the value. To change the value press CLEAR and then
enter the desired value. Press ENTER to exit this mode.
