Abstract
A controller which receives a signal from an external associated energy utility indicative of a forthcoming rate increase period, and controls the rate of temperature change of a refrigerator from a user selected setpoint to a first targeted setpoint below the user selected setpoint. During the rate increase the controller establishes a second target setpoint above the user selected setpoint. After the rate increase period the controller reduces the temperature to the user selected setpoint at a constant rate defined by a number of degrees per minute.
