General Information
The BACnet Flow Controller (BFC) is a BTL listed DDC fan controller designed specifically for controlling flow through Fan Filter
Units (FFU) with EC motor technology. The BFC controls an EC motor 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.
NOTE: This manual only covers the BFC controller. For troubleshooting an ECM motor, please visit http://www.priceindustries.com
and download the ECM Motor Troubleshooting Manual.
