The BACnet Flow Controller (BFC) is a DDC fan controller designed specifically for controlling flow through Fan Filter Units (FFU) with EC motor technology. The BFC can control up to two ECM motors through a local setpoint which is adjustable using a push button interface on the BFC, by an analog BAS input voltage, or over BACnet.
In addition to fan control, the BFC can monitor filter pressure drop, filter loading, signal for filter changes, monitor the motor and filter lifetime in hours, as well as report airflow and air temperature over the filter. This information can be viewed from the LCD screen on the front of the BFC controller, or over BACnet on a building management system.
