A regulating system (100) can include a first controller configured to receive analog input (105, 106) and discrete input (110, 11), a second controller communicatively coupled to the first controller, and configured to receive analog input (105, 106) and discrete input (110, 111), a selector (150) communicatively coupled to the first controller and second controller and configured to select either one of the first controller and the second controller as a master for the regulating system (100) and state logic residing on each of the first controller and second controller to determine which of the first and second controller is the master.
