Abstract: Architectures and techniques are presented that can more efficiently route excess air flow by intelligently selecting the zones to which the excess air flow is to be routed. Excess air flow results from an HVAC device providing (e.g., at a minimum setting) a volume of air that is greater than what is demanded by a zone that triggers activation of the HVAC device. As one example, excess air flow can be routed to a zone or zones that are determined to be most likely to trigger a subsequent activation condition that would cause the HVAC device to be activated again at a future time.
