Electronically controlled operation of blinds=shutters and awnings and similar

摘要

The method of control is carried out using an electronic control unit, with the operation of the shutters carried out by a direct or indirect control of the direction of rotation of a drive motor, to open or close the shutters. The times for the opening and closing vary according to the time of year and are stored in the control unit. A table is stored in the control unit, the values of which are formed from the difference between a curve and the associated reference time. The control unit contains a determined addressing and computing process. With the help of the table values, the times for the sunrise and the sunset can be determined for any day of the year, without a significant amount of accuracy loss.
