The HVAC controller of claim 1, wherein the controller is further configured to display two or more selectable options for responding to the user query about the utility saver switch on the display of the HVAC controller, wherein at least one option, when selected, confirms the utility saver switch is present and causes the controller to dismiss the alert displayed on the display of the HVAC controller. 4. The HVAC controller of claim 1, wherein the controller is further configured to display two or more selectable options for responding to the user query about the utility saver switch wherein at least one option, when selected, causes the controller to display at least one other possible cause for the alert displayed on the display of the HVAC controller. 5. The HVAC controller of claim 1, wherein the controller is further configured to display two or more selectable options for responding to the user query about the utility saver switch wherein at least one option, when selected, causes the controller to display a screen that allows the user to disable diagnostics for a period of time. 6. The HVAC controller of claim 1, wherein the controller is configured to accept an entry from a user indicating a heating equipment type through the user interface and wherein upon indication of the heating equipment type, the controller is further configured to determine if the heating equipment type may include a utility saver switch. 7. The HVAC controller of claim 1, wherein the controller is configured to accept an entry from a user indicating a cooling equipment type through the user interface and wherein upon indication of the cooling equipment type, the controller is further configured to determine if the cooling equipment type may include a utility saver switch. 8. The HVAC controller of claim 1, wherein the controller is further configured to detect a type of HVAC equipment and to determine if the HVAC equipment may include a utility saver switch. 9. An HVAC controller configured to control one or more components of an HVAC system, the HVAC controller comprising: a user interface including a display;a memory;an I/O block for receiving one or more signals from the HVAC system and for providing one or more control signals to the HVAC system;a controller coupled to the memory, the user interface and the I/O block, the controller is configured to: monitor one or more signals received from the HVAC system via the I/O block that are related to a current performance level of the HVAC system:determine if the current performance level of the HVAC system falls below a minimum performance level; andin response to determining that the current performance level of the HVAC system has fallen below the minimum performance level, the controller is configured to display a user query on the display of the HVAC controller that queries the user about whether a utility saver switch is present, and two or more selectable options on the display of the user interface for responding to the user query, wherein at least one selectable option, when selected, indicates that a utility saver switch is not present. 10. The HVAC controller of claim 9, wherein the controller is further configured to display an alert on the display of the HVAC controller when the controller determines that the current performance level has fallen below the minimum performance level. 11. The HVAC controller of claim 10, wherein the controller is further configured to simultaneously display the user query and the alert on the display of the HVAC controller. 12. The HVAC controller of claim 9, wherein the controller is further configured to accept entry of an HVAC equipment type from a user through the user interface of the HVAC controller, and wherein the controller is further programmed to determine that the HVAC equipment type may include the use of a utility saver switch. 13. The HVAC controller of claim 12, wherein the HVAC equipment type is a type of cooling equipment. 14. The HVAC controller of claim 12, wherein the HVAC equipment type is a type of heating equipment. 15. The HVAC controller of claim 9, wherein the controller is further programmed to detect an HVAC equipment type, and wherein the controller is further programmed to determine that the HVAC equipment type may include the use of a utility saver switch. 16. The HVAC controller of claim 9, wherein the controller is further configured to display two or more selectable options on the display of the user interface for responding to the user query about whether the utility saver switch is present, wherein at least one selectable option, when selected, indicates that a user is uncertain about whether the utility saver switch is present. 17. The HVAC controller of claim 10, wherein the controller is further programmed to display two or more selectable options on the display of the user interface for responding to the user query about whether the utility saver switch is present, wherein at least one selectable option, when selected, confirms the presence of the utility saver switch and causes the controller to dismiss the alert. 18. The HVAC controller of claim 10, wherein the controller is further configured to display two or more selectable options on the display of the user interface for responding to the user query about whether the utility saver switch is present, wherein at least one selectable option, when selected, causes the controller to display at least one other possible cause for the user alert. 19. The HVAC controller of claim 9, wherein the controller is further configured to determine the current performance level of the HVAC system based, at least in part, on a current delta T value and a delta T limit stored in the memory of the controller. 20. A method of monitoring a performance of an HVAC system, the HVAC system including one or more HVAC components that are controlled, at least in part, by an HVAC controller having, a user interface including a display, a memory, and a controller, the method comprising: the controller monitoring one or more signals from the HVAC system to determine a current performance level of the HVAC system; andthe controller displaying a user query on the display of the HVAC controller that queries the user about whether a utility saver switch is installed in response to determining that the current performance level of the HVAC system has fallen below a predetermined minimum performance level. 21.
