Systems and methods of controlling a heating, ventilating, and air conditioning system are provided that operate according to signals returned from return air temperature sensors as well as the supply air temperature sensors. Using predetermined temperature setpoints, return temperature information, and supply temperature information, the HVAC system is configured to maintain the temperature of a room first, by the use of its cooling valve, and second and only when the capacity of the cooling valve has peaked, by use of the fan. The presently disclosed improved HVAC system operates more efficiently by avoiding unit loading hopping and minimizing power consumption.

1. A method for configuring a heating, ventilation, and air conditioning 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;controlling a fan and a cooling valve of the at least one HVAC unit based on the received return air temperature signal and the received supply air temperature signal, wherein controlling the fan and the cooling valve comprises: comparing the received return air temperature signal with the received supply air temperature signal;controlling the cooling valve based on the step of comparing the received return air temperature signal with the received supply air temperature signal;controlling the fan to increase a speed of the fan based on the cooling valve operating at a maximum capacity. 2. The method of claim 1, further comprising: generating a cooling valve drive signal according to at least one of return air temperature signal and supply air temperature signal. 3. The method of claim 1, wherein the controlling step further comprises: controlling the fan to operate at a minimum speed based on a capacity of the cooling valve. 4. The method of claim 1, wherein the step of controlling the fan to increase the speed occurring after a predetermined period of time. 5. The method of claim 1, wherein the controlling step further comprises controlling the cooling valve to operate at a minimum capacity based on comparing the return air temperature signal with a cooling valve setpoint temperature. 6. The method of claim 1, wherein the HVAC system is configured to control the temperature of one or more computer systems. 7. The method of claim 1, wherein the HVAC system is configured to be used in a commercial area. 8. A heating, ventilation, and air conditioning system, the system comprising: at least one HVAC unit, each HVAC unit including: at least one fan;at least one cooling valve;a processor, said processor coupled to the least one fan and the at least one cooling valve, said processor, said processor is adapted to execute instructions to perform the following: 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;controlling the at least one fan and the at least one cooling valve of the at least one HVAC unit based on the received return air temperature signal and the received supply air temperature signal, wherein controlling the at least one fan and the at least one cooling valve comprises: comparing the received return air temperature signal with the received supply air temperature signal;controlling the at least one cooling valve based on the step of comparing the received return air temperature signal with the received supply air temperature signal;controlling the at least one fan to increase a speed of the at least one fan based on the cooling valve operating at a maximum capacity. 9. The system of claim 8, said processor is further adapted to execute instructions to perform the following: generating a cooling valve drive signal according to at least one of return air temperature signal and supply air temperature signal. 10. The system of claim 8, wherein the processor's controlling of the at least one fan and the at least one cooling valve further comprises: controlling the at least one fan to operate at a minimum speed based on a capacity of the at least one cooling valve. 11. The system of claim 8, wherein the processor's controlling of the at least one fan to increase the speed occurring after a predetermined period of time. 12. The system of claim 8, wherein the processor's controlling of the at least one fan and the at least one cooling valve step further comprises controlling the cooling valve to operate at a minimum capacity based on comparing the return air temperature signal with a cooling valve setpoint temperature. 13. The system of claim 8, wherein the HVAC system is configured to control the temperature of one or more computer systems. 14. The system of claim 8, wherein the HVAC system is configured to be used in a commercial area.
