A system for self-provisioning building equipment includes a main control unit having a processing circuit and a data communications interface and an auxiliary control unit connected with the main control unit via a communications network. The system includes a memory device having an update file stored therein. The update file includes a plurality of partitions, each partition containing provisioning data for a programmable component of the main control unit or the auxiliary control unit. The processing circuit includes a provisioning manager configured to monitor the main control unit and the auxiliary control unit for a predetermined trigger and automatically initiate a provisioning process in response to detecting the predetermined trigger. The provisioning process includes providing the provisioning data from the update file to the programmable component of the main control unit or the auxiliary control unit.
