Abstract
A user interface for a load control device allows a user to control an operating characteristic of a load to a plurality of discrete levels. The user interface comprises an adjustment member for allowing the user to select one of the discrete levels and a linear array of status indicators for displaying the discrete level. The number of discrete levels is greater than the number of status indicators. According to a first embodiment of the present invention, either one status indicator or two consecutive status indicators are illuminated to indicate the presently selected discrete level. According to a second embodiment, a fully illuminated status indicator is surrounded by two dimly illuminated status indicators to indicate the presently selected discrete level. According to a third embodiment, a single status indicator may be illuminated to indicate one or more of the discrete levels.
