Abstract
A method for controlling a sealed system including a variable speed compressor coupled to a controller includes defining a first set of temperature ranges for operating the compressor during a temperature increase period, defining a second set of temperature ranges for operating the compressor during a temperature decrease period, the second set of ranges different than the first set of ranges, and operating the compressor using the defined first set and the defined second set.
