    BACnet Points List Download Equipment-specific BACnet® points lists are available on trane.com product page. Object Naming Conventions The communicated points for the Symbio™ controllers are generally named according to their function. While many of the points are read-only, others include both read and write capability. The established naming convention helps to identify the capabilities of each point.
