The list has 54 objects: occupied/standby/unoccupied setpoints, damper and economizer settings, occupancy, mode and emergency commands, enables for economizer, compressor and auxiliary heat, sensor values the BAS can override, and status, run-time and fault values. Which objects apply depends on the unit's software model.",
