The Model C controller is our simplest to use controller. Easy manual control is
achieved by adjusting a digital thumbwheel switch. It may also be operated
remotely via voltage or resistance programming. Fully solid state and built
in-house by Sigma factory trained personnel, the Model C controller uses a lead
proportional, lag dampening, automatic mode selecting control for optimum
precision and reliability. The Model C controller features:
