Identify the amount of energy saved for each load when the load is shed. Enter this amount in the Load Ratings table while defining the Load extension. If the load is a multistate object, you must determine the energy savings associated with each of its possible states. If a particular state is not specified in the Load Ratings table, DLLR does not shed the load when the output is in that state. Also, because the DLLR feature sheds loads to meet a specified target, you must identify the savings expected when a particular load is shed. Table 1 shows a few examples.

Also consider that DLLR uses the savings rate that is less than or equal to the Shed command for analog loads. For example, using the analog output in Table 1, if the output value is 89% when the load is shed, DLLR reports 2 kW saved.
