摘要: A method for determining a fully extended position of screening body (14) device (12) roof window. The comprises control unit comprising data storage device, an electric motor (18) tachometer (181), roller tube (15), and first second spring element (164, 174). the steps driving from retracted to position, in which elements 174) are tensioned tension level, T1, stopping at point T2, above measuring number revolutions, Rd, (15) necessary drive said is stopped, storing measured Rb, theroller tube, that release corresponding difference, ΔT, between will cause move back towards calculating value R = Rd – Rb.
