A visual display system for use with a menu driven digital thermostat is provided. The visual display system provides a relative indication of the total number of menu items in the displayed menu on the thermostat's user interface display. A relatively sized and positioned scroll bar is utilized in one embodiment to provide such relative visual cue to a user of the position of the currently selected menu item and the total number of menu items available in the list. Directional icons may also be utilized to provide as visual cue regarding which way within the list the user is able to maneuver during operation. Both vertical and horizontal scroll bars and/or directional icons may be provided.
