This section helps to standardize the BACnet Objects exposed with respective to 75F® data points. BACnet objects are created based on 75F® system, zones, and modules paired and exposed from CCU to the BACnet network with BACnet protocol.  

These are used by Facility Managers (Organizational, Primary and Secondary) and installer (In-Site personnel who have access to CCU Settings).  

Following are the list of objects exposed from 75F® for better understanding:
