ABSTRACT:
In a remote control unit for modifying the operating states of physically spaced operating units such as the volume control of a stereo system, the color control of a television set and the brightness control of a lighting fixture, a first key is actuated to call up in a predetermined sequence the different floors of a building in which the operating devices are disposed. The floors are identified on a display as they are called up. Upon, actuation of a second key, further actuation of the first key calls up the different rooms on the last-displayed floor of the building, the rooms being identified on the display. Upon another actuation of the second key, yet further actuation of the first key calls up the operating devices or units disposed within the last room called up by actuating the first key. A reset key is provided for returning to the first member of the uppermost hierarchical grouping (i.e., the first-displayed floor). Other keys are provided on the remote control unit for modifying the operating state of a device selected by actuation of the first two keys.
