a controller for modifying output of the heat source,
a control knob to select an operating condition of a plurality of operating conditions of the controller, wherein the control knob comprises:
a circular electronic display screen that is touch sensitive to provide a graphic user interface (GUI),
a bezel surrounding the circular electronic display, the bezel being configured to rotate freely about the circular electronic display,
a sensor to determine the relative orientation of the bezel,
