Heating, ventilation, and air conditioning management system and method

A method for configuring a heating, ventilation, and air conditioning (HVAC) system, the system including at least one HVAC unit, each unit including at least one control circuit, the method comprising:

• receiving a return air temperature signal at a control circuit of the at least one HVAC unit;
• receiving a supply air temperature signal at the control circuit of the at least one HVAC unit;
• generating a first cooling valve drive signal based on a comparing of the return temperature signal and a return setpoint temperature;
• generating a second cooling valve drive signal based on a comparing of the supply temperature signal and a supply setpoint temperature;
• controlling a fan and a cooling valve of the at least one HVAC unit based at least on the received return air temperature signal, the received supply air temperature signal, a return setpoint temperature, and a supply setpoint temperature;
• wherein the controlling of the cooling valve is based on a comparison of a priority associated with the first cooling valve drive signal and a priority associated with the second cooling valve drive signal.
