 "summary": "The EOS BTCII control on PVI water heaters speaks BACnet MS/TP (or Modbus RTU) directly from the back of its touch screen. It exposes only Analog Inputs and Analog Values: system status and alert, target and system temperature, the heater's probes, ignition state, modulation, relay states, flame current, run hours, cycles and error code, plus writable system enable, setpoint, heater enable and pump force-on outputs. Cascade objects are present but not used on water heaters.",
