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 system device coupled to a data bus. The system device includes a functional block adapted to respond to a message received via the data bus. The system device is configured to thereby enter a disabled state in which the system device does not provide a service or broadcast messages via the data bus, but may continue to receive messages via the data bus.
