 "summary": "The Edge [ii] controller on AERCO water heaters talks BACnet IP on its Ethernet port or BACnet MS/TP on the J14 RS-485 terminals. Standalone and client units expose analog inputs for status, temperatures, valve position, O2 and combustion-calibration data plus analog values for setpoints and setup. A WHM manager adds plant values and a read-only block for each of up to 16 units. Only analog inputs and analog values are used.",

  "Access is given per table in the manual (AI tables read only, AV tables read/write), not per point; it is applied that way here.",

On a standalone unit or WHM client the same IDs are calibration history instead (AI 99-106 Previous O2 at Cal 1-8, AI 107-114 Previous NOx at Cal 1-8, AI 115-122 Previous CO at Cal 1-8) and AV 53 is FFWD Temp Display.",
  "AI 123-138 (previous calibration points and flame strength) are from the standalone/client table; the manager table marks AI 123-151 Not Used.",
  "The WHM manager repeats a read-only block for each of up to 16 units; only unit 1 (AI 300-319) is listed here. Unit n uses the same names at AI 300 + 100 x (n - 1) to 319 + 100 x (n - 1), so unit 16 = AI 1800-1819.",
