Abstract

A system for controlling a capacity of a motor-driven, multi-capacity compressor operable at each of a plurality of capacity levels. The system includes a controller configured to selectively couple the compressor to either a line-voltage terminal or a drive configured to control a speed of the motor. Embodiments of the controller can cause the compressor to operate in each of (1) a first mode, powered by the drive, and at a first capacity, (2) a second mode, powered by the line-voltage terminal, and at the first capacity, or (3) a third mode, powered by the line-voltage terminal, and at the second capacity.
