An electronically actuated system for a control clock device is provided with an instrument panel arranged in such fashion that an operator having virtually no familiarity with the technical aspects of the system can set up a program of activity, such for example as the playing of various melodies on a carillon on different days of the week, and varying them automatically from day to day. The panel is provided with controls in the form of push buttons, dials and lights, appropriately labeled, a digital clock face showing the time of day in hours, minutes and seconds, selectors for the day or days during the week when a program is to be played, and a selector for any one or more of the programs from a bank of programs. Visual displays show what has been set up in the device as a check against errors which the operator may have made during the setting. In the event an error has been made there is a control button for erasing the error so that a correct setting can be substituted and, after all settings have been properly made and entered in the system, another control means makes possible setting the clock to the correct time of day whereafter operation will continue automatically. At any later date by manipulation of another control device the operator can quickly review an entire week's schedule of programs so that desired changes can be made in part or all of the schedule.
