A zone controller system that includes global communication of inputs, outputs and controller states from all zone controllers allowing each zone controller to operate based on inputs, outputs and controller states from all other zones. The zone controller system may also include direct one-to-one communication connections that allow additional communications. The system may include a user interface to configure operation of the zone controllers utilizing programmable logic equations that may use as variables the inputs, outputs and controller states of any zone controller. The user interface may be implemented in an off board configuration tool that is run on a computer connected to the global network. The system may also utilize one-to-one communications connections to provide self-repair and auto-configuration features. Each zone controller may store its ID(s) and configuration parameters on two other zone controllers, where they can be recovered for self-repair and auto-configuration.
