Abstract
A temperature control system for a building is disclosed utilizing a central demand limit controller. The system includes a number of control modules or thermostats that have both proportional error and integral error functions. The integral error is reset at intervals by an interstage differential to drop single stages of air conditioning. This reduces demand until the maximum allowed demand is met. The integral error function is a timed function and the stages return in a random manner to restore setpoint temperature.
