I have purchased a commercial (Omega) temperature controller for a lab experiment. The unit seems to work quite well but the manual that came with the controller assumes a fair amount of familiarity with the jargon associated with control engineering and only explains how to set the various conditions in the controller. I was expecting at least a theory of operation or some explanation of what the various terms mean. I'm familiar with PID control terminology but things like Set point 2 and it's meaning and use are pretty obscure. Could someone point me to a short tutorial or web article that would clear up some of the mysteries for me?
