Abstract
A refrigerator control according to the present invention allows a user to establish one or more set points for controlling the temperature of one or more refrigerated compartments. Means are provided for selecting either a normal mode of operation whereby the set points may be manually established by a user or a priority mode of operation which overrides the normal mode whereby each set point is established at a preselected value so that the refrigerator is optimally operated in anticipation of expected operating conditions. Means are additionally provided for preventing erroneous entry of manually established set points.
