Control systems and methods for control of heating, ventilation, air conditioning, and refrigeration (HVACR) systems that include cooling and one or both of heating and heat recovery can include adaptive and balanced modes for each of heating and cooling operations. The adaptive heating and cooling modes each respectively include controlling the HVACR system to achieve a target temperature for the respective heating or cooling process fluid and to unload or stop the compressor when the temperature of a the other of the cooling or heating process fluid exceeds a threshold. The balanced heating and cooling modes respectively include controlling a quantity of flow of the cooling or heating process fluids to meet balanced heating or cooling target temperatures for the respective heating or cooling process fluids and also the other of the cooling or heating process fluid.
