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.

The enumeration is defined in Table 104.
