The Demand Limiting feature helps you save money by limiting peak energy usage. The Load Rolling feature helps save money by reducing overall energy consumption. The DL portion of DLLR selectively turns off (sheds) equipment, such as fans and lights, or adjusts setpoints to limit energy use during peak times. The LR portion acts continuously to maintain a specified energy reduction by shedding unnecessary loads. A facility can implement either one or both of these strategies.
The DLLR object represents the attributes, commands, and reports that define the DLLR functionality. For information on the features and operation of DLLR, refer to the DLLR Technical Bulletin (LIT-12011288).
