A simple programmable, smart system that controls lights and saves energy in a commercial space. Energi Savr Node can be used to control digitally addressable or third-party ballasts and drivers, and connect wired and wireless occupancy/vacancy sensors,daylight sensors, and wallstations to manage light in a variety of spaces. These components increase space flexibility, improve occupant comfort and productivity and reduce maintenance costs. Ideal for retrofits and new construction, each Energi Savr Node module can be installed locally, without connecting to a central panel.
