The points list has 168 objects: setpoints and configuration as AVs, alarms and enables as BVs, and a few multistate values such as BAS On/Off and System Mode. It covers single-zone (space temperature) and VAV (supply air temperature and duct static) operation, plus water economizer, hot gas reheat and auxiliary hot water heat options.",

  "Water economizer, hot gas reheat, auxiliary heat, humidity and CO2 points only apply when those options are installed and enabled.",
