Abstract
An apparatus and method for controlling a sealed system including a variable speed compressor coupled to a controller is described. The method includes establishing a control grid having at least one axis corresponding to a temperature at a specified location, and the axis is divided into a plurality of operating states of the sealed system. Each of the states correspond to a sensed temperature condition at the specified location, and each of the states includes a designated compressor speed parameter. The compressor speed parameter in some of the states is different from the compressor speed parameter in other of the states.
