3rd party setpoint controllergreenspun.com : LUSENET : PID Controller Tuning : One Thread
i've desinged an industrial oven that heats using a PID controller. However, I am not the end user. While the end users require a high degree of acuracy in temperatures--which the PID provides--they only use between 6-8 different temperature setpoints throughout the day.
I would like to provide a solution found on most phones or car radios--presets. but, i am not having much luck finding a source of such a device that will work with my current setup (or if worse comes to worse--a replacement PID that is easy to set--i.e. one-button easy)
can anyone recommend a source for such an external 'box' that would essentially provide 6-8 'one-touch buttons' by which setpoints could easily (easily* means easily by the enduser's definition) be made and chosen. IME this solution will have to be no more difficult than setting a phone or car radio preset--which excludes my current PID controller.
thanks for any assistance.
