 "summary": "The CALEC ST II is an energy calculator that takes a flow meter and a matched pair of temperature sensors and works out energy, power, flow, volume and mass. With the BACnet MS/TP interface it exposes up to 16 Analog Inputs and two relay Binary Outputs. Which AIs exist depends on the meter version (Volume, Mass, Flow, BDE, TGR, BDV, DTF).",

  "Units shown are the defaults; each AI's units can be changed within an allowed list (energy, volume, mass, power, flow and temperature units).",
  "The two auxiliary inputs take pulses from extra meters such as water or oil meters.",
  "BO 0 and BO 1 are relays 1 and 2; the document gives no names for them beyond 'Relay 1' and 'Relay 2'.",
  "The device object reports vendor name 'Aquametro AG' and vendor ID 431."
