Abstract
A demand limit control system for maintaining power consumption of loads within a building below an upper demand limit, the upper demand limit being separated from a lower demand limit by a deadband, the system having a power demand controller responsive to power consumption for providing a controller output signal ramping up when the power consumption is above the upper demand limit, remaining substantially constant when power consumption is between the upper and lower demand limits, and ramping down when the power consumption is below the lower demand limit, and a plurality of demand controlled loads each connected to the power demand controller and each responding to a different threshold value of the controller output signal such that each load is conditioned to turn off when the controller output signal is above the threshold and is conditioned to turn on when the controller output signal is below the threshold.
