General description of the User Interface
The function of the User Interface is to provide to the User which functions are active and/or selectable and if
there is some failure or alarm condition. Some loads (such as heater, paddle switch, step motor) will be driven
directly by the User Interface Board, but according to Control Board instruction; no logic will reside in the board.
