Page 3: Product Overview General Information
BACNet Flow CoNtroller PRODUCT OVERVIEW General Information 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 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. -

Page 12: Filter Calibration
BACNet Flow CoNtroller FILTER CALIBRATION Filter Calibration To properly track filter loading, the BFC must be calibrated with the clean filter pressure. Before proceeding, ensure the unit is operating at the desired airflow. Any changes to the airflow will change the unit pressure and therefore require the filter status to be reset. -

For further information on BFC BACnet setup, see Networking & Setup section. STEP 1: Ensure that BACnet point AV2 – Filter Runtime is being pulled in (see table below). STEP 2: Write a value of 0 to AV2 –... -

EVERY device on the network must run at the same speed. 76800 Price controllers are defaulted to a baud rate of 76800, but can be changed to 38400, 19200, or 9600. For a network segment with all Price controllers, it’s recommended that the baud rate be left at 76800. -

BACNet Flow CoNtroller NETWORKING & SETUP BACnet Networking and Setup Setting the MAC Address: MAC (media access control) must be UNIQUE on an MS/TP network segment within building. An installer setting up an MS/ TP segment must ensure each device has a UNIQUE MAC Address (Range 1-99). The MAC Address is set through the LCD thermostat or LCD setup tool. -

BACNet Flow CoNtroller NETWORKING & SETUP Setting the Device Instance (Coupled MAC and DI) Device Instance: A Device Instance number identifies a device within an entire building, therefore giving it a unique number or Address, much like a telephone ext. number. A building can have one telephone number, but all the extensions have a unique number to identify them. -

Please ensure you have all components before proceeding. Inspect components for shipping damage. Do not install components that appear damaged. Contact your local PRICE Sales Rep for quick ship replacements. As always, for the latest information and 3. DIN RAIL video please visit priceindustries.com. -
Page 23: Location
NETWORKING & SETUP location The Front-End components should be mounted in an accessible location close to a network connection. Price suggests mounting these components in the network or server room. The WEB-SERVER, PRTU-IP-RTR, PRTU-BAC-RTR, and PRTU-IP-SWITCH (if applicable) should all be mounted together. -
Page 24: Mounting
Using 3 screws (by others) mount the DIN rail horizontally to a secure, accessible surface. Hang the Price PRTU-WEB onto the DIN rail using the TOP white clips. Using the Price Electronics screwdriver, gently pull down on the BLACK clip, while pushing gently on the WEB- SERVER towards the DIN rail. -

Page 26: Analog Rpm Feedback
BACNet Flow CoNtroller NETWORKING & SETUP Analog rPM Feedback A two wire connection supplies an analog (0-10 VDC) signal that is directly proportional to the MOTOR 1 RPM. The range is 0 – 2500 RPM and it will output a proportional 0 – 10 VDC signal. If a dual blower system is used, only the RPM of motor 1 can be read. -
Page 27: Wiring And Cables
NETWORKING & SETUP wiring and Cables *For In depth ECM motor troubleshooting, please refer to ECM Troubleshooting Manual on Price Industries’ website. The ECM speed controller requires 24 VAC power from a transformer and outputs control signals to the ECM motor on dual MTA- 100 jacks. -
Page 28: Maintenance Troubleshooting
Keep this consistency throughout the network. Option #2 Price does not use EOL or termination on their devices. Terminating a device is almost never required at the low baud rate of MS/TP devices. In fact terminating can create more problems than it solves. -
