Abstract
The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In an embodiment, the network includes a user interface and a system device. The user interface is configured to publish a privilege request message to a data bus. The system device is configured to receive messages via the data bus and to store configuration data in nonvolatile memory. The system device is further configured to enable a privileged operating mode not normally available to a user of the network in response to the privilege request message.
