ABSTRACT:
The learning method is one which comprises an action of the installer having at least as consequences the ending of the powering of motor controlling the translational movement of the slats in the direction of extending, if this movement is in progress, and/or the initialization of a motor displacement amplitude or activation time counter, and, so long as this action is maintained; the powering of a motor for controlling the orientation displacement of the slats of the screen, the incrimentation of the counter, then when this second action ceases; the recording of the value of the counter in a register for storing a data relating to the total orientation travel, the powering of the motor controlling the translational moment of the slats in the direction of retracting, if the action has not brought an end to a translational movement of the slats in the direction of extending.
