The Leviton® Lumina® RF Decora® 0 to 10 V dimmer room controller with 5 A relay (DL057) is the primary user interface for a Lumina RF standalone room controller system, combining both familiar toggle on/off control, dimming control and energy management business logic into line voltage powered wireless communication devices. The DL057 manages a room by coordinating activities of all Lumina RF Standalone devices within the space and can be used to control loads up to 5 A. The DL057 works with compatible Lumina RF standalone devices to create an advanced intelligent lighting system that can be used to comply with IECC, ASHRAE 90.1 and 2019 Title 24, Part 6 occupancy/vacancy sensing, 0 to 10 V dimming and daylight harvesting requirements. Dimming, multi zone daylight harvesting, occupancy and vacancy sensing, manual control and scene control are configured using the Bluetooth® enabled Lumina RF standalone app.
