Status BIs and diagnostic BIs share one range (BI 1-157), so check the name, not the number range.

  "Trane titles this list 'HDWA (UC800)' and does not explain the suffix in the document. This list uses short instance numbers (AI 1, AV 1, BI 1...) unlike the standard Symbio 800 lists with 5-digit instances, so check which list matches the controller on site.",

  "Binary inputs from the 'Binary Input Diagnostics' table are individual alarm flags (0/off = normal, 1/on = in alarm); they share one instance range with the status BIs.",
  "The diagnostic table also gives each alarm's reset level (Local or Remote); it is not carried over here.",
  "The Symbio 800 integration guide (BAS-SVP083) covers BACnet IP and BACnet MS/TP; the rotary address sets the MS/TP MAC and a default Device ID of 1-127, and a software Device ID can be set instead.",
