Hvac controller with user activated performance test

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;
• and
• a controller coupled to the memory, the user interface and the I/O block, the controller programmed to receive a delta T test request via the user interface, and once received, execute a delta T test with at least one equipment stage of the HVAC system operating, the controller further programmed to identify a current delta T for the HVAC system with the at least one equipment stage operating, and to display on the display of the HVAC controller the identified current delta T.
