Abstract
An HVAC system may include a VAV box including a damper movable between a first damper position and a second damper position and an HVAC controller that is mounted remotely from the VAV box. The HVAC controller may be configured to control the VAV box in accordance with a temperature set point entered into the HVAC controller and may be programmed with a test and balance procedure. In some cases, the HVAC controller may also be programmed with functionality that facilitates an installer or other technician in configuring and/or reconfiguring the VAV box. This may include providing a user interface that supports a test and balance procedure of the VAV box. Such functionality may be user-accessible via the user interface of the HVAC controller, and in some cases, may be used to drive the damper of the VAV box between various damper positions as well as perform other functionality.
