1. A zoning system for a heating, ventilation, and/or air conditioning (HVAC) system having a plurality of zones, comprising:
a controller having a damper support limit, wherein the controller is configured to:
receive a first call for conditioning from a first zone that includes a first plurality of dampers and receive a second call for conditioning from a second zone that includes a second plurality of dampers, wherein a sum of the first plurality of dampers and the second plurality of dampers exceeds the damper support limit of the controller such that a cumulative quantity of dampers to be actuated at a particular time exceeds the damper support limit of the controller;
determine a first user-selected zone priority level of the first zone and a second user-selected zone priority level of the second zone, wherein the first user-selected zone priority level and the second user-selected zone priority level indicate relative priority values of the first zone and the second zone with respect to one another; and
control operation of the HVAC system to sequentially actuate the first plurality of dampers and the second plurality of dampers based on the first user-selected zone priority level of the first zone and the second user-selected zone priority level of the second zone to satisfy the first call for conditioning and the second call for conditioning and to operate a damper sum within the damper support limit of the controller.
