I've always struggled with understanding proportional band - even after watching a number of videos trying to explain it. Now I've got a fan regulator that has a temperature sensor and a potentiometer. It works by sending a signal (0-10V) to the fan if the ambient temperature drops below a certain value. It also has a knob where the temperature proportional band can be set between 1-8°C. I think it means how much the temperature is allowed to drift past the set point before the fan starts or stops. Is that about right...?
