Abstract

A heating, ventilation, and air conditioning (HVAC) system may be zoned into one or more zone. The HVAC system may include one or more register vents that may include vent dampers. The HVAC system may be controlled by an HVAC control system including a communications port or block, a controller operatively coupled to the communications block, and a user interface. The controller may receive sensed data received at the communications block from sensors of the HVAC system. Based, at least in part, on the received sensed data, the controller my determine recommended settings for at least one of the manually adjustable register vent dampers and display the recommended settings on the user interface.
