A method of determining a wiring configuration for one or more HVAC components operably coupled to one another and operably coupled to a main system controller comprising a processor and a display is provided. The method includes prompting a user with the processor to define the one or more HVAC components being installed; and determining with the processor the wiring configuration required for the one or more HVAC components defined. A wiring diagram is displayed on a display that corresponds to the wiring configuration required.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method of determining a wiring configuration for one or more HVAC components operably coupled to one another and operably coupled to a main system controller comprising a processor and a display, the method comprising: prompting a user with the processor to define the one or more HVAC components being installed; determining with the processor the wiring configuration required for the one or more HVAC components defined; and displaying on the display a wiring diagram that corresponds to the wiring configuration required. 2. The method of claim 1 further comprising prompting the user to define the HVAC components being installed using an interface on the display. 3. The method of claim 1, wherein the main system controller comprises a thermostat. 4. The method of claim 1, wherein the main system controller is portable. 5. The method of claim 1 further comprising powering the main system controller with an auxiliary power supply. 6. The method of claim 1 further comprising displaying the wiring diagram on a mobile device display. 7. The method of claim 1 further comprising updating with the processor the wiring configuration required for the HVAC components defined. 8. The method of claim 1 further comprising dynamically updating the wiring diagram with the processor based on changes in the HVAC components defined. 9. A method of determining a wiring configuration for one or more HVAC components operably coupled to one another and operably coupled to a main system controller including a processor and a display, the method comprising: prompting a user to define on the display of the main system controller the one or more HVAC components being installed; receiving input from the user through an interface on the display, the input being indicative of the one or more HVAC components being installed; determining with the processor the wiring configuration required for the one or more HVAC components defined; and displaying on the display a wiring diagram that corresponds to the wiring configuration required. 10. The method of claim 9, wherein the main system controller comprises a thermostat. 11. The method of claim 9, wherein the main system controller is portable. 12. The method of claim 9 further comprising powering the main system controller with an auxiliary power supply. 13. The method of claim 9 further comprising updating with the processor the wiring configuration required for the one or more HVAC components defined. 14. The method of claim 9 further comprising dynamically updating the wiring diagram with the processor based on changes in the one or more HVAC components defined. 15. A device for determining a wiring configuration for one or more HVAC components operably coupled to one another, the device comprising: a processor in communication with an input device, wherein the input device is configured to receive input from a user that defines one or more HVAC components being installed, the processor determining the wiring configuration required for the one or more HVAC components defined; and a display in communication with the processor, wherein the display is configured to display a wiring diagram that corresponds to the wiring configuration required. 16. The device of claim 15 further comprising an interface on the display to prompt the user for the input that defines the equipment being installed. 17. The device of claim 15, wherein the device is at least one of a thermostat or a mobile device. 18. The device of claim 15 further comprising an auxiliary power supply. 19. The device of claim 15, wherein the processor updates the wiring configuration required for the one or more HVAC components defined. 20. The device of claim 15, wherein the processor dynamically updates the wiring diagram based on changes in the one or more HVAC components defined. 21. An HVAC communicating device comprising: a receiver to wirelessly receive device data from a plurality of HVAC components, the data comprising device identification information; a memory to store a plurality of wiring diagrams to assist in connecting HVAC components; and a processor to determine a preferred at least one of the plurality of wiring diagrams based on the received device identification information. 22. The device of claim 21, further comprising a display to display the at least one preferred wiring diagram. 23. The device of claim 21, further comprising a wireless transmitter to transmit the at least one preferred wiring diagram to a display device. 24. The device of claim 21, wherein the receiver receives the device data via near field communication.
