Abstract
The device comprises a control point (CP) equipped with Up and Down contacts, the actuation of which causes the rotation of the motor in the desired direction, a control and supply box (CB) containing a logic processing unit (LPU), switching means controlled by the logic unit and means for establishing a direction of rotation of the motor. The means for establishing a direction of rotation of the motor furthermore comprise means (LPU, CLK, DC) for recognizing the direction of rotation of the shutter or roller blind, a memory of EEPROM type (MI) for recording the direction of rotation of the motor instruction issued by the control point and a programmed processor for comparing the recognized direction of displacement with the instruction emanating from the control point.
