The SRP-22 roller shutter controller is designed to control window blinds or other devices powered by single-phase 230 VAC motors. Control can be performed wirelessly using transmitters or the exta life controller, or wired using reflective blind pushbuttons. Wired control uses inputs IN1 and IN2, configured in the mobile app. The inputs can operate in local or central control modes. In both cases, double and single roller shutter pushbuttons can be used. Thanks to bidirectional communication between the receiver and the controller, the current roller shutter status is displayed in the mobile app via an appropriate icon and the "closing level" parameter. Bidirectional communication also allows for controller parameterization and remote assigning of transmitters (without physical access to the receivers). A frame coding algorithm ensures control security, which is particularly important for window blinds and garage doors. In addition to the controller, the SRP-22 can be controlled simultaneously using exta life system transmitters. Multiple transmitters can be assigned to the receiver, allowing for independent control from multiple locations. The device is designed for installation in flush-mounted and surface-mounted installation boxes. The receiver features a remote software update function via the controller. Programmable roller shutter movement time and the ability to define up to four favorite settings further enhance the controller's functionality.
