Abstract:
1. A method for configuring a heating, ventilation, and air conditioning (HVAC) system, the system including at least one HVAC unit, each unit including a control circuit, the method comprising: receiving a return air temperature signal at the 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 controlling comprises controlling the cooling valve to increase the cooling valve's water output based on comparing the first cooling valve drive signal and the second cooling valve drive signal.
