Abstract (en)

[origin: EP0447849A1] An electronic control for a roller blind contains a control device (2) with a front plate (4) in which a display (8) and a keyboard (10) are constructed, and a housing (6), which is situated on the rear side of the front plate and accommodates the control part and power part. By actuating individual keys of the keyboard (10), control signals are generated in the control part which cause the power part to rotate a motor, which drives the roller blind, in one or the other direction, so that the roller blind is opened or closed. Located in the control part is an annual calender unit which allows automatic generation of the abovementioned control signals as a function of the time of day of sunrise and sunset. A counter unit serving as a clock supplies to a comparator a time-of-day value which, for the purpose of opening or closing the roller blind, is compared with a time value read out of a table memory or calculated. In the event of agreement, the corresponding control signal is generated. <IMAGE>
