 "summary": "LEGIOMIXevo is an electronic 3-way mixing valve controller for domestic hot water that holds the mixed outlet temperature and runs scheduled thermal disinfection (anti-legionella) cycles. Over BACnet IP it exposes the mixing, recirculation and storage temperatures, the mixing setpoint, the running function and alarm codes, relay states, feature flags and identification strings.",

  "Relay BVs: 1 = relay closed, 0 = not closed (written here as Open/Closed). Temperature units follow the Units property (°C, °F).",
  "The Network Port object (no instance printed) is left out.",
