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.
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.

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 airflow balancing please refer to the FFU Manual. Filter calibration can be performed either directly
through the BFC interface or over BACnet. Each method is described below.
Using the BFC Interface
STEP 1: To calibrate clean filter pressure drop, scroll through the ‘Service Menus’ until reaching ‘Filter’. Select this menu by
pressing the ‘Enter/Menu’ button (far right).
NOTE: To enter the Service Menu, hold down the ‘Enter/Menu’ button for 5 seconds. Display will show ‘Passcode’. Use
the Up and Down arrow buttons to enter this sequence:
Down, Up, Up, Down.
STEP 2: Scroll through the ‘Filter’ menu until reaching ‘Reset Filter’, select by pressing the ‘Enter/Menu’ button.NOTE: Make sure
the area directly beneath and around the unit is clear of any personnel or equipment as this can affect the reading of the
clean filter static pressure.
STEP 3: Press the ‘Enter/Menu’ button to confirm reset of filter; this will begin calibration. This will take approximately 2 minutes.
After filter calibration is complete, LCD will display:
‘RESET COMPLETED’.

The steps below require the BFC to be configured and set up on a BACnet front-end system.
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 – Filter Runtime. This will initiate a calibration cycle. The current unit pressure (AI5) will be
automatically be copied to the Filter Calibrated Pressure (AV5). This process takes approximately 2 minutes.
NOTE: Filter loading can subsequently be monitored using BACnet point: AV1 – Filter Load (from 0% clean to 100% loaded).

BACNET WIRING
BACnet Wiring
The Price BACnet Flow Controller (BFC) has the option of
using a CAT 5 cable to run BACnet MS/TP, or cable hardwired
into a pluggable terminal block (see next page if using
hardwired BACnet connections). The RJ-45 jacks for use with
the supplied BACnet cables are directly tied to the pluggable
terminal block, and so any combination of supplied cables
and hardwired connections can be used on a single network
segment.
BACnet networks must be run in a daisy chain configuration,
meaning there is only one main cable and each network device
is connected directly along its path, with no more than 30
devices per segment, and MS/TP segment lengths must not
exceed 1050 feet.
Termination
BACnet MS/TP networks must be terminated to ensure proper
operation. A network should be terminated twice, once at
the beginning and once at the end. Termination helps reduce
reflections and noise. The terminating can be done with a 100
ohm resistor across the + and - lines. Termination can also be
done via software using the Price BACnet Flow Controller. For
more information see the BACnet Service Menu section of this
manual.
Tech Tip: The Price BACnet MS/TP to IP Router has built
in termination and it is enabled by default (since the router is
typically the beginning of the entire MS/TP network). Now you
only have to go and find/terminate that last device.
Electrical Noise
Electrical noise can affect both analog signal and digital
communications such as BACnet. Therefore do not route
high voltage lines next to the BACnet network! Avoid noisy
electrical sources such as:
• Variable Frequency Drives
• High current power lines
(main panel feeds)
• Fluorescent light fixtures
If you must pass near noisy electrical lines cross at right
angles. This will help reduce the amount of noise coupled to
the network wires.

NETWORKING & SETUP
Use Price supplied CAT-5 cables for BACnet whenever
possible. If not possible to use Price supplied cables,
follow these wire specifications.
Network Wire Specifications
For the BACnet MS/TP network specific wire is required.
Do not use standard power or “thermostat” wire. This
wire does not have the necessary requirements for digital
communications. While it’s possible it may work (temporarily)
the network will be unreliable and not operating at optimal
performance.
BACnet MS/TP Wire type recommendations
• Use 2 balanced twisted pairs, one for + and -, one for
NET COM
• Low capacitance (17pF or less)
• Plenum rated (FT6, CMP ratings)
• 100-120 ohm, Balanced
• (CAT5, CAT5E, CAT6 network cable has excellent
specifications and will work in almost any BACnet MS/TP
application.)
• Price controllers use the Orange Compliment
for (+), the Orange for (-), and the Brown and
Brown Compliment together for the (NET COM)
connections. These are paired in a standard CAT5E
cable. Pre-terminated CAT5 cables are available from
Price. Model code: NETC35 (35 ft plenum rated cable,
terminated with RJ45 plugs, 568-B standard)

BACnet Service Menu
Each controller’s MAC address, Device Instance, and Baud rate are set in the BACnet sub-menu of the service menu accessed
through the LCD screen on the face of the BFC. For information on how to select a MAC address and Device instance for any
controller on a network, see following pages.
To set the controller’s BACnet settings, enter the Service Menu and adjust settings as follows:
NOTE: When the screen displays a flashing value, that value is ready to be changed and can be adjusted by pressing the arrow
keys. Pressing Menu will save the value.
Hold down the Menu button on the LCD Thermostat for
5 seconds until prompted for a passcode; use and

The screen will now display “SERVICE MENU: FAN”
Scroll down to the BACnet sub-menu.
Press the Menu button to enter this menu.
Screen will now show “MAC ADDRESS = 1”. This is the
default setting and can be programmed between 1 and 99 by
pressing Menu and using the UP and DOWN arrows ( ).
Use to scroll to whatever MAC you are intending to set this
controller to, once you arrive at the number, press Menu to
save
NOTE: By default, the MAC address will appear as the last 2
digits of the device instance.

The device instance defaults to 100, but will be displayed with

device instance.
NOTE: Each Menu press will change allow changes in different
tiers of the device instance (so that you don’t have to scroll for
extended periods to get into the millions range – supposing
that’s where you need to set your device instance)
The baud rate is the speed that the MS/TP network runs at.
EVERY device on the network must run at the same speed.
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.
*Choose lower baud rates only when integrating with devices

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.
NOTE: Each device on a network segment must be set to run at the same speed or baud rate.
NETWORK SEGMENT #1
NETWORK SEGMENT #2
24 VAC power HOT and COMMON polarities are critical and must not be reversed on ANY devices! Reverse polarity will stop
communication on that MS/TP segment. All 24 VAC transformers must be grounded on their secondary side for BACnet to work.
NET COM wire must be connected at each device and is critical for BACnet network reliability.
Use one twisted pair for + and -, and another twisted pair for NET COM for optimal noise cancellation.
