1. An HVAC data processing and communication network, comprising:
- a system device, that includes an HVAC component configured to provide an HVAC function, configured to;
generate an alarm, and locally store an alarm record, in response to an alarm condition with respect to said HVAC component; and
receive an alarm request message via a data bus and in response publish an alarm reporting message over said data bus, said alarm reporting message indicating a level of said alarm; and
a user interface configured to receive said alarm reporting message and display an alert depending on said level of said alarm wherein said alarm clears after expiration of a predetermined time period if all service bits associated with said system device are set.

Abstract
The disclosure provides an HVAC data processing and communication network and a method of manufacturing the same. In one embodiment the network includes a system device and a user interface. The system device is configured to generate and locally store an alarm record in response to an alarm event. The system device is further configured to receive an alarm request message via a data bus. In response to receiving the alarm request message, the system device is configured to publish an alarm reporting message over the data bus. The user interface is configured to receive the alarm message and display an alert depending on a state of the flag.
