3-channel sun protection control (REG) for operating roller shutters, fabric, slat, and window products. It features 3 potential-free outputs that can be expanded by connecting motor control units. The control of the connected products is based on measurements of brightness, twilight, wind speed, precipitation, ice, time, outdoor temperature, and indoor temperature. An indoor temperature sensor is integrated into the control unit. Up to 4 individual scene states can be accessed at the touch of a button. Operation is carried out via touch-sensitive sensor buttons and a sensor dial. The quick start menu allows for rapid commissioning with just a few selection steps. The Wisotronic 3-channel consists of a control unit and a separate power unit, which differs in its mounting type and is mounted externally. Various housing variants are available for different mounting situations of the control unit. The elegant design is achieved through nearly flush installation in an optionally available hollow wall housing. Additionally, operation via radio using EWFS handheld or wall transmitters is also optionally possible. The color of the control panel is white.
