System units are central components of the control device for iNELS RF Control. It receives values from the components, processes the set programs, and send commands for switching and control. Two-way communication visualizes the current state of the components. The RF Touch Controller and the smart RF eLAN-RF box (which allows smart phone control) are the TOP and most commonly used system components. Within the installation, they can control up to 40 components, create scenes, monitor the cameras, and monitor energy.
