and a computing device in communication with the first plant controller and the second plant controller and configured to: receive an indication of a parameter modification made to the master controller on the first channel; and communicate the parameter modification to the second plant controller; wherein the second plant controller is configured to propagate the parameter modification to the subset of the plurality of controllers on the second channel that are follower controllers of the master controller of the first channel. ### Claim 2 (depends on 1) The system of claim 1, wherein: an additional subset of the plurality of controllers on the first channel are not follower controllers of the master controller; and an additional subset of the plurality of controllers on the second channel are not follower controllers of the master controller. ### Claim 3 (depends on 1) The system of claim 1, wherein each of the plurality of controllers on the first and second channels is configured to control a different variable air volume device. ### Claim 4 (depends on 1) The system of claim 1, wherein the parameter modification is an adjustment to a setpoint of the building system. ### Claim 5 (depends on 1) The system of claim 1, wherein each of the plurality of controllers on the first and second channels is a same controller type. ### Claim 6 (depends on 1) The system of claim 1, wherein the computing device is configured to receive the parameter modification during a commissioning of the plurality of controllers on the first and second channels. ### Claim 7 (depends on 1) The system of claim 1, wherein the parameter modification is made to the master controller to correct an error. ### Claim 8 (depends on 1) The system of claim 1, wherein the computing device is configured to receive the parameter modification from a user. ### Claim 9 (depends on 1) The system of claim 1, wherein the computing device is configured to communicate the parameter modification as logic to the second plant controller. ### Claim 10 (depends on 1) The system of claim 1, wherein the first channel is a first floor of a building having the building system installed therein, and wherein the second channel is a second floor of the building. ### Claim 11 (depends on 1) The system of claim 1, wherein the computing device is local with respect to the first plant controller, the plurality of controllers on the first channel, the second plant controller, and the plurality of controllers on the second channel. ### Claim 12 (depends on 1) The system of claim 1, wherein the computing device is remote with respect to the first plant controller, the plurality of controllers on the first channel, the second plant controller, and the plurality of controllers on the second channel. ### Claim 13 A computing device for building system controller configuration propagation, comprising: a processor; and a memory having instructions stored thereon which, when executed by the processor, cause the processor to: determine a modification made to a parameter of a first unitary controller of a building system; configure the first unitary controller as a master controller; configure a second unitary controller of the building system as a follower controller, wherein the second unitary controller is a same controller type as the first unitary controller; define a set of propagation rules associated with the master controller; propagate the parameter modification to the follower controller according to the rules; and receive a status of the propagation of the parameter modification to the follower controlled according to the rules. ### Claim 14 (depends on 13) The computing device of claim 13, wherein the building system is a heating, ventilation, and air conditioning system of a building, and wherein the master controller and the follower controller control different portions of a same floor of the building. ### Claim 15 (depends on 13) The computing device of claim 13, wherein the memory includes instructions stored thereon which, when executed by the processor cause the processor to revert the master controller and the follower controller to a previous configuration state responsive to a user input. ### Claim 16 (depends on 13) The computing device of claim 13, wherein the memory includes instructions stored thereon which, when executed by the processor cause the processor to propagate the parameter modification to the follower controller via a remote server.
