Abstract
The present invention provides for a control system for operating a heating, ventilation, and air conditioning (HVAC) system. A controller operates compressors in tandem. In response to detection of a high pressure condition in refrigerant flowing through a high pressure side of the HVAC system, the controller operates the HVAC system with a first compressor on and a second compressor off.
