First Claim
Patent Images
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; and
a controller connected to the memory and the user interface, the controller programmed to monitor a delta T 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 a delta T limit stored in the memory of the HVAC controller.

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.
