MULTISENSOR ROOMSET The 331 Multisensor for RoomSet is the heart of Helvar RoomSet single-room lighting solution for commissioning classrooms, offices and meeting rooms. For the installer, the automatic preset programming allows for swift out-of-the-box installation, with no configuration needed. RoomSet supports advanced graphical configuration via an easy-to-use Android app that enables a quick and simple setup for different purposes, such as presentations, lectures or conferences, or for daylight-harvesting. For commissioning large numbers of rooms, the RoomSet app allows copying room layouts, thus making the commissioning process faster and consequently more costeffective. The Multisensor for RoomSet has a light sensor for constant-light control, and a passive infrared (PIR) presence detector to provide energy-saving functions in a DALI system. It also hosts a microcontroller running RoomSet firmware with Bluetooth® low-energy connectivity to allow tablet-based configuration. Status/Indicator ring Light sensor Key Features • Excellent detection performance through high sensitivity and multidirectional coverage. • Automated addressing and defaults programming to allow installer testing. • Functional system just by powering on the sensor. • Drag-and-drop graphical configuration of rooms with an intuitive Android app. • Over-the-Air upgrades via the RoomSet app to keep the system up to date with the latest available functionality. • Programmable constant-light control for energy efficiency. • Cost-effective deployment of large numbers
