The device has a RAM (50) storing rotational directions of an asynchronous motor (12) based on its supply and information of an apron`s displacement direction of a roller/window blind (16). A microprocessor (48) is associated to a ROM (52), where the microprocessor and the ROM associate codes with the rotational directions. A logical processing unit (46) actuates rising and descenting control knobs (22, 24) of a control point (20) to cause the rotational directions causing respective rising and descenting of the apron in a normal operating phase, after an operation of linking the directions. |
