The air conditioning system is controlled as shown below by AIRSTAGE Cloud Site Manager.

(a) Site
     This is the entire air conditioning system to be controlled by one AIRSTAGE Cloud Edge Supervisor.

(b) Building
    These are buildings or facilities that make up the Site.

(c) Floor
    These are hierarchies that make up the Building.

(d) Zone
    Zone is a specific physical space in the building and Zone is tied to Floor. Devices listed under “Devices” can be registered in Zone.

(e) Devices
    These are the individual devices connected to the AIRSTAGE Cloud Edge Supervisor. All devices such as indoor units, sensors, and external devices that are monitored by the AIRSTAGE Cloud Site Manager are applied.

An administrator or a Technician can set the composition of the Building, Floor, and Zone arbitrarily.

The target value of Zone state is set to the Zone Function Controller in the Site Manager. Zone Function Controller controls each device to achieve a set target value. As a result, Zone is kept comfortable. The current Zone Function Controller has a temperature control function. In the future, Zone Function Controller will be able to control various devices registered in Zone, such as ventilation and lighting, in order to achieve higher levels of energy saving.
