7.7.1 Overview
The AirConnectionType is a non-tangible component representing the state of a connection from the ducting system to a filter unit. The connection can be open or closed. The open state represents a state of the ducting system where air can pass through to the filter unit.
It is formally defined in Table 40.

| BrowsePath | Attribute Description |
| Humidity | Value of the humidity sensor |
| Temperature | Value of the temperature sensor |
| Airflow | Value of the air flow sensor |
| GasQuality | Value of the gas quality sensor |
| Pressure | Value of the pressure sensor |
| ConnectionOpen | Indicates the connections status (open, closed, or a state in between) |
| Malfunction | Indicates that the AirConnection is malfunctioning, i.e., an error occurs in a component that provides functionality for this abstract component; e.g., an error in the ducting system or a valve. True in case of error. |
The Open and Close Methods can be called to open or close the connection. In a complex ducting system that consists of a network of joints and junctions, opening or closing the connection may involve switching multiple valves.
The control logic for switching the state of the ducting system is determined by the server implementation.
The air connection may contain optional sensors for humidity, temperature, air flow, gas quality, and air pressure.
The server sends a MalfunctionAlarmType event when the Malfunction property changes.
The AirConnectionStatusChangedConditionType event is triggered when the ConnectionOpen property changes.
