US Patent 9971363 HVAC controller for a variable air volume (VAV) box

An HVAC controller configured to control a VAV box including a damper may include a temperature sensor that is configured to sense a temperature proximate the HVAC controller and a touch screen user interface that is configured to display the sensed temperature and to enable a user to input a temperature set point. A controller may be operatively coupled to the touch screen user interface and the temperature sensor and may be configured to regulate operation of the VAV box in accordance with the sensed temperature and the temperature set point. The HVAC controller may be programmed with a test and balance procedure that is user-accessible via the touch screen user interface.
