BACnet Flow Controller for Fan Filter Units | Product Overview
General Information
The BACnet Flow Controller (BFC) is a DDC fan controller designed specically for controlling ow through Krown Fan Filter
Units 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 lter pressure drop, lter loading, signal for lter changes, monitor the motor
and lter lifetime in hours, as well as report airow and air temperature over the lter. This information can be viewed from
the LCD screen on the front of the BFC controller, or over BACnet on a building management system.

BACnet Flow Controller for Fan Filter Units | Filter Calibration
Filter Calibration
To properly track lter loading, the BFC must be calibrated with the clean lter pressure. Before proceeding, ensure the unit is
operating at the desired airow. Any changes to the airow will change the unit pressure and therefore require the lter status
to be reset. For further information on airow balancing please refer to the Krown Fan Filter Unit 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 lter 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 lter static pressure.
Step 3: Press the ‘Enter/Menu’ button to conrm reset of lter; this will begin calibration. This will take approximately 2
minutes.
After lter calibration is complete, LCD will display:
‘RESET COMPLETED’.

BACnet Flow Controller for Fan Filter Units | Filter Calibration
Via BACnet
The steps below require the BFC to be congured 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 Keystone 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
conguration, 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 reections 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
Keystone BACnet Flow Controller. For more information
see the BACnet Service Menu section of this manual.
Tech Tip: The BACnet MS/TP to IP Router supplied by
Keystone 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 nd/
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 xtures
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.

BACnet Flow Controller for Fan Filter Units | Networking & Setup
Use Keystone supplied CAT-5 cables for BACnet
whenever possible. If not possible to use Keystone
supplied cables, follow these wire specications.
Network Wire Specications
For the BACnet MS/TP network specic 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.)
•Keystone controllers use the Orange Compliment
for (+), the Orange for (-), and the Brown and Brown
Compliment together for the (NETCOM)
connections. These are paired in a standard CAT5E
cable. Pre-terminated CAT5 cables are available from
Keystone (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 ashing 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
to enter the passcode; DOWN, UP, UP, DOWN.
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

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. Keystone controllers are defaulted to a baud rate
of 76800, but can be changed to 38400, 19200, or 9600.
For a network segment with all Keystone controllers, it’s
recommended that the baud rate be left at 76800.
*Choose lower baud rates only when integrating with
devices by other manufacturers whose maximum speed
is lower than 76800 (eg. 38400).

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.

TECH TIP
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.
