The present invention provides a control system for managing lubricant (11) levels in tandem compressor assemblies (100, 101, 102) of a heating, ventilation, and air conditioning (HVAC) system (1000, 1002). In transitioning from a partial load that operates a first compressor (101) but not a second compressor (102) of a tandem assembly to a full load that operates both the first and the second compressor (101, 102), a controller (128) of the HVAC system (1000, 1002) turns OFF both compressors of the tandem compressor assembly (100, 101, 102) to allow time for lubricant levels (11) to equalize between the first and the second compressor (101, 102). |
