The Leviton Decora Wireless 0-10V Dimmer Room controller with 5A Relay (DL057) is the primary user interface for a wireless dimming 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 wireless standalone devices within the space and can be used to control loads up to 5A. The DL057 works with compatible wireless devices to create an advanced intelligent lighting system that can be used to comply with IECC, ASHRAE 90.1, and Title 24, Part 6 occupancy/ vacancy sensing, 0-10V 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.
