9.3 AirConnectionOpenEnum
This enumeration AirConnectionOpenEnum describes whether the air connection is open, i.e., it is in a state in which air can be passed through. This may be physically determined by the states of the valves of a ducting system. As a system may need time to alter the state of its valves, the enumeration can also represent intermediary states where the connection is neither open nor closed.
