Abstract: The controller may be equipped with a user interface that allows the user to monitor and adjust various parameters of the controller. With more modern designs, the user interface typically comprises a liquid crystal display (LCD) or light emitting diode (LED) display inset within a controller housing that contains a microprocessor or the like, an I/O interface, and other components of the controller. The user interface may include a menu-driven interface that allows the user to scroll through one or more menus or screens to adjust the different settings on the controller. In some cases, a routine programmed within the controller prompts the user at each menu or screen to input various commands into the interface to adjust the controller settings.
