Abstract: Examples of the present disclosure relate to systems and methods for providing an elevated third-stage of operation to a two-stage compressor of a climate control system. The first low stage and the second high stage are provided with open or closed bypass ports respectively and by operating the two-stage compressor at a rated power setting. The elevated third-stage of operation is provided by operating the two-stage compressor at the high stage with an overdrive power setting. The elevated third-stage may be enabled in heating mode and locked out in cooling mode. The two-stage compressor may be further locked out of the second high stage in cooling mode and an indoor fan may be operated at various speeds to provide additional cooling capacity. Switching between each stage of the two-stage compressor may be controlled by additional control circuitry including a plurality of relays.
