Abstract
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.
