An HVAC controller may be programmed to monitor a current delta T of an HVAC system and to determine a performance level of the HVAC system based, at least in part, on one or more delta T limits stored in the memory of the HVAC controller. The HVAC controller may be further programmed to display or provide a user alert if the performance level falls outside of a normal operating range for the HVAC system.

1. 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;a controller connected to the memory and the user interface, the controller programmed to monitor a delta T that is representative of a difference in temperature between a return air side and a discharge air side of an HVAC system during operation of the HVAC system, and to determine a performance level of the HVAC system based, a least in part, on one or more delta T limits stored in the memory of the HVAC controller; andwherein the controller is configured to record a delta T fault in the memory of the HVAC controller if the monitored delta T falls outside of one or more of the delta T limits for at least a predetermined amount of time during a current HVAC cycle, the controller further configured to determine whether to display on the display of the HVAC controller a user alert based at least in part on a count of the delta T faults recorded within a predetermined period of time or during a predetermined number of HVAC cycles. 2. The HVAC controller according to claim 1, wherein the one or more delta T limits includes the minimum delta T limit and/or a maximum delta T limit stored in the memory of the HVAC controller. 3. The HVAC controller according to claim 1, wherein one of the one or more delta T limits is a delta T off limit. 4. The HVAC controller according to claim 1, wherein the controller is configured to determine the performance level of the HVAC system using a minimum delta T limit, wherein the controller determines that the HVAC system is outside of an expected performance level if the monitored delta T is below the minimum delta T limit. 5. The HVAC controller according to claim 1, wherein the controller is configured to compare the monitored delta T to a maximum delta T limit stored in the memory of the HVAC controller when determining the performance level of the HVAC system. 6. The HVAC controller according to claim 4, wherein the minimum delta T limit corresponds to a specific stage and operational mode of the HVAC system. 7. The HVAC controller according to claim 1, wherein the controller is configured to record a delta T fault in the memory of the HVAC controller if the monitored delta T falls below a minimum delta T limit after a predetermined measurement time delay, and the delta T fault does not occur during one or more user specified conditions. 8. The HVAC controller according to claim 7, wherein the controller is configured to display a user alert only after two or more delta T faults are recorded by the controller within the predetermined period of time or during the predetermined number of HVAC cycles. 9. The HVAC controller according to claim 1, wherein one or more of the delta T limits stored in the memory of the HVAC Controller is user definable. 10. 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 memory, a controller, and a user interface with a display, the HVAC system operating in a number of HVAC cycles, the method comprising: the controller monitoring one or more signals from the HVAC system to determine a current delta T value for the HVAC system, wherein the current delta T value is representative of a difference in temperature between a return air side and a discharge air side of the HVAC system during operation of the HVAC system;the controller determining a performance level of the HVAC system based, a least in part, on the current delta T value and a delta T limit stored in the memory of the HVAC controller;wherein the controller is configured to record a delta T fault in the memory of the HVAC controller if the current delta T falls outside of the delta T limit for at least a predetermined amount of time during a current HVAC cycle; andwherein the controller is configured to determine whether to display on the display of the HVAC controller a user alert based at least in part on a count of the delta T faults recorded within a predetermined period of time or during a predetermined number of HVAC cycles. 11. The method according to claim 10, wherein the delta T limit is received from a user via the user interface of the HVAC controller. 12. The method according to claim 10, further comprising accepting one or more user specified conditions during which delta T faults will be ignored. 13. The method according to claim 10, wherein the delta T limit comprises a maximum delta T limit. 14. The method according to claim 10, wherein the delta T limit comprises a minimum delta T limit. 15. The method according to claim 10, wherein the delta T limit comprises a delta T off limit. 16. The method according to claim 10, further comprising comparing the current delta T value to a maximum delta T limit and a minimum delta T limit stored in the memory of the HVAC controller to determine if the performance level of the HVAC system falls within a desired performance band. 17. The method according to claim 16, wherein when the current delta T value is greater than the maximum delta T limit or less than the minimum delta T limit, the performance level of the HVAC system is determined by the controller to be outside of the desired performance band. 18. 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; anda controller connected to the memory and the user interface, the controller programmed to monitor a current delta T that is representative of a difference in temperature between a return air side and a discharge air side of an HVAC system, and to determine a performance level of the HVAC system based, a least in part, on one or more delta T limits stored in the memory of the HVAC controller;wherein the controller is configured to record a delta T fault in the memory of the HVAC controller if the monitored delta T falls outside of the one or more delta T limits for at least a predetermined amount of time during a current HVAC cycle,the controller further programmed to display on the display of the HVAC controller a user alert, wherein the controller determines whether to display the user alert based at least in part on a count of the delta T faults recorded within a predetermined period of time or during a predetermined number of HVAC cycles.
