Flexit's basic list has 66 rows: ventilation mode commands and status, setpoints, timers for fireplace and rapid ventilation, sensor readings, outputs and A/B alarm handling. Several rows give two or three instance numbers because the object moves with the configured input or output terminal; each printed instance is listed here.",

  "Many objects exist only when the matching option is configured (water or electric heating, cooling, duct pressure fan control, wireless room sensors CI75/CI76/CI77).",
