Abstract:
1. A method of determining a shading and ventilation venting position (PIA) in a control system of an actuator ( 11 ) which is used to move a sun-protection, privacy or closure device ( 1 ) comprising stackable slats ( 2 , 3 ) connected together by perforated parts ( 4 ), which method comprises the following steps: identifying, by analyzing the torque exerted on the actuator ( 11 ), the final slat position (PLF) in which the bottom slat ( 3 ) is at the limit of contact with the bottom end stop of the device ( 1 ), assigning to this final slat position (PLF) a data (dPLF) defining said position, calculating a shading and ventilation position data (dPIA) defining the shading and ventilation position (PIA) from the data (dPLF) of the final slat position (PLF), and storing the shading and ventilation position data (dPIA) in a shading and ventilation position memory ( 13 ).
