Distributed nodes, such as intelligent register controllers, of a heating, ventilating and / or air conditioning (HVAC) system wirelessly communicate with each other on a peer-to-peer basis, forming a network, and collectively control the HVAC system, without a central controller. The intelligent register controllers collectively control the amount of conditioned air introduced into each region. Each node may base its operation at least in part on information about one or more (ideally all) of the other nodes. Each intelligent register controller automatically determines how much conditioned air to allow into its region, or how much return air to allow to be withdrawn from its region, based on information collected by the register controller, such as: current temperature of the region; desired temperature of the region; calculated amount of conditioned air required to change the region's temperature to the desired temperature; temperature of conditioned air begin supplied by a duct to the register; current time, day of week, vacation or other schedule data; temperatures of other regions and their respective desired temperatures; calculated amounts of air required to be supplied or withdrawn by the other controlled registers to change their respective regions' temperatures to their desired temperatures; or combinations thereof. Each register controller automatically determines when and to what extent to operate its respective controllable damper.
