Method for controlling a motorised roller shutter installation with guidable slats

摘要: The method involves positioning orientable strips such that the extend parallely to a visually detectable horizontal plane in reproducible manner. current position of is recorded as single reference position. An extreme orientation or relative mechanical tilter (8) determined from based on adaptable dimension data thickness and height strips, diameter winding tube (3) and/or dimensions tilter. Independent claims are also included for following: (1) operating motorized roller blind installation (2) control unit controlling an actuator installation, comprising activation part.
