 "summary": "Apex boilers with the Panasonic display and 4109 software are read over Modbus RTU by the Thermal Solutions Universal Gateway (a ProtoNode) and served as BACnet IP or BACnet MS/TP devices. The 28-object profile has a burner on/off command, writable CH, DHW, lead lag and CH time-of-day setpoints, setpoint sources, sensor temperatures, burner state, lockout and hold codes, and cycle counters.",

  "The Universal Gateway is a ProtoNode (BACnet RER FPC-N34-0816, LonWorks LER FPC-N35-0817) that auto-discovers up to 8 boilers on its Modbus RS-485 port.",
  "Every boiler is its own BACnet device with the same object list; the instances here are for one boiler.",
  "Power all boilers and connect them before running auto-discovery; a boiler added later is not found until discovery is run again.",

  "enable": "BV 1 Burner On Off enables or disables the burner. If only BV 1 is used instead of the boiler's Enable/Disable contact, the boiler stops but the system pump may keep running.

  "setup": [

   "S-bank DIP switches pick the protocol (S0-S2 all Off = BACnet IP, S0 On = MS/TP multiple node, S2 On = MS/TP single node); S3 On at power-up runs auto-discovery (about 3 minutes), then set S3 Off to keep the configuration.",
   "MS/TP MAC address 1-127 on A-bank DIP switches (one MAC for the whole gateway); baud rate on B-bank switches.",
