The alre BACnet single room controller with graphic display has been specially developed for time-dependent heating and cooling operation in 2- or 4-pipe systems. The controller can be used and applied in a wide range of areas, such as hotels, residential, office and commercial premises as well as hospitals and schools. The device has two inputs and three outputs. Two of the outputs switch relays, each of which can address up to 5 valve actuators. The third output is analog (0-10 V) and can be used for EC fan control, for example. One of the two inputs is used for BACnet communication, the other can be configured to connect sensors, e.g. for temperature or dew point. Windows or presence contacts can be connected via BACnet.
␍Suitable for all standard switch ranges. The alre BACnet individual room controller is mounted in the flush-mounted box. The housing fits exactly into the design frames of sizes 50 x 50 mm, 55 x 55 mm and 60 x 60 mm from the surface switch ranges of well-known manufacturers such as Berker, Busch-Jaeger, Gira, Jung, Merten, Peha, Hager or Feller (CH). Special colors for projects on request.
␍Communication takes place via BACnet in accordance with DIN EN ISO 16484-5 with the BACnet MS/TP network protocol. This makes the room controller compatible with all common building automation systems. The controller complies with the BACnet profile “B-AAC” (BACnet Advanced Application Controller) and is therefore much more than a simple setpoint device. In contrast to other fieldbus interfaces such as LON or KNX, the BACnet interface does not require an additional gateway for implementation and communication with the management level. This saves costs because no service technicians with different qualifications are required to commission the system. A further cost saving compared to distributed solutions is achieved by combining the room operating unit and individual room controller in one device.
␍The predefined applications cover a wide range of applications for room temperature control in room automation.
␍The BACnet room controller has been awarded the BTL certificate for compliance with the BACnet standard ISO 16484-5, which has been verified by means of a BTL conformity test.
