BACnet Integration Level Device

BACnet Web Embedded F.C.U Controller

WC-FB is a B-AAC class BACnet LAN communication integration controller.


WC-FB is a B-AAC class BACnet LAN communication integration controller. It has a Router function, Stand alone, and Web Embedded operation system. It is possible to remote control fan coil units in another building.

Users can monitor and control each individual FCU or a group of fan coil units through an internet browser. Control functions include Start/Stop, Temperature Setting, Fan Speed Setting, Scheduled On/Off etc. The user can monitor temperature, fan speed, and system status remotely. The WC-FB has a BACnet Ethernet port which enables information to be passed to the BACnet Management level.
