Abstract
A climate-control system includes a variable-capacity compressor. An outdoor ambient temperature sensor indicates a temperature of the outdoor ambient air. A return air temperature sensor indicates a temperature of the return air in the system. A controller commands a startup compressor stage based on the temperature from the outdoor ambient temperature sensor and commands a running compressor stage based on a time-based slope of the temperature from the return air temperature sensor and the startup compressor stage.
