 "summary": "CenCon is Engineered Air's unit controller, with BACnet MS/TP (19200 or 38400 baud), BACnet IP and Modbus RTU. It works as a virtual BACnet gateway: the CenCon device (Gateway ID + 1) reports the main sensors, analog outputs, fan, damper and alarm relays and the safety inputs, and each fitted expansion module (DX cooling, indirect and direct gas heat, gas humidifier, energy recovery wheel, electric heat, spare I/O, combustion blower and pressure) appears as its own device. All objects here are read-only; commands go to the CenCon_SW device.",

The same object type and instance repeats on different devices.",
  "Module devices appear only when that expansion module is fitted.",
  "Temperatures marked 'value x10' are integers in tenths of a degree F; most other analogs are raw signals in mV or kOhm.",
  "The XP_XM table gives only terminal names (S1, AI1-AI4, AO1-AO2, DI1-DI4, DO1-DO4).",
  "Points marked (FUTURE) in the manual are listed as printed.",
