-47- "ELECTRONIC PROGRAMMABLE CONTROLLER DEVICE" ABSTRACT OF THE DISCLOSURE An electronic programmable controlling device for electrical apparatus includes a real time clock and time and sensor memory units which can be programmed from a keyboard. Comparators compare real time with programmed time for controlling the electrical apparatus and also for comparing programmed sensor data with input sensor data also for controlling the electrical apparatus either separately or together with the time data. Day of the week switches are operable to select which days the con- troller controls the electrical apparatus. Error indicat- ing means are provided to detect programming error, and a single display unit is selectively connectable to display time of day, day of week, programmed key input data and time and sensor memory contents. A BCD output is provided connectable to a recording or display device such as a computer terminal, printer or the like. The device is powered from 110 VAC or from a battery and the display unit indicates power failure or the decrease of battery voltage below a predetermined level.
