 "summary": "The BCI2-C is a non-programmable Trane controller that connects to the CH530 chiller controls over the IPC3 link and serves the chiller data on BACnet MS/TP. This list is the RTWD column of the guide's model tables: 102 objects with low instance numbers. The BAS writes chilled and hot water setpoints and current limit (AO), auto/stop and diagnostic reset (BO) and chiller mode (MO); everything else is read-only water, refrigerant, oil, compressor and electrical data.",

  "The guide's tables mark each object against RTWD, RTUD, RTHD, RTAC, CGAM/CXAM and CGWN/CCUN; this file holds the RTWD column. The RTUD column is the same except that it adds AI 42/43 Airflow Percentage (circuits 1 and 2), and the AO setpoint table has no RTUD column.",
  "The BCI2-C self-configures, so only the objects that match the connected chiller show up.",
  "The tables have no read/write column: AI/BI/MI are read-only, and the AO/BO/MO objects (listed with relinquish defaults) are the BAS setpoints and commands, marked writable here.",
  "Units are given as a quantity (Temperature, Pressure, Percent...); SI or I-P follows the BCI2-C Device Units setting. Two printing slips are corrected here: AI 12 is described as circuit 2 in the guide, and BI 24's active state is printed 'None' (it means alarm).",
  "On RTWD, AO 4 Hot Water Setpoint is for leaving condenser water temperature control, and AI 24 Unit Power Consumption needs the power meter option.",
  "Trane's Symbio 800 'RTWD (CH530)' points list (BAS-PTS035A) uses the same numbering but lists only 47 analog inputs; this guide adds the AO/BO/MO commands and the BI/MI status objects."
