Introduction The ST3134 KNX Blind Actuator SC 4-fold is a special control for blinds with SC 3-wire connection (SL MB blinds). Due to the fully digital and bidirectional communication between ST3134 and the motor control unit (inside the blind) the ST3134 realize precise position control and feedback and therefore allows perfect sun tracking and integration into building management systems.
