1. A heating, ventilation, and air condition (HVAC) system, comprising:
a plurality of discrete HVAC units, wherein each HVAC unit of the plurality of discrete HVAC units is configured to condition a zone associated with the HVAC unit, and each of the plurality of discrete HVAC units are networked together, wherein each HVAC unit comprises an HVAC unit controller, one or more controllable HVAC components, and a network interface, wherein the network interface is configured to transmit zone condition data of the zone associated with the corresponding HVAC unit and HVAC component operational state data of the corresponding HVAC unit to each of the other HVAC units of the plurality of discrete HVAC units, and to receive zone condition data and HVAC component operational state data from each of the other HVAC units, and wherein for each HVAC unit, the corresponding HVAC unit controller is configured to independently operate and control the corresponding controllable HVAC components according to the zone condition data and the HVAC component operational state data corresponding to the HVAC unit and according to the zone condition data and the HVAC component operational state data received from the other HVAC units to enable discrete zone control by each HVAC unit controller using local zone condition data and the HVAC component operational state data as well as external zone condition data and the HVAC component operational state data from each of the other HVAC units; and
a plurality of sensors positioned in each zone, wherein each sensor of the plurality of sensors is coupled to the HVAC unit controller of the HVAC unit associated with the zone, and is configured to sense a condition characteristic of the zone and transmit corresponding sensed zone condition characteristic data to the HVAC unit controller.
