AntecControls.com |FHC - Manual
Product Overview
The Fume Hood Controller (FHC) is an
exceptionally versatile controller for
monitoring and controlling fume hood
face velocity. Designed specifically
to meet the needs of all fume hood
types, the FHC provides assurance
that required fume hood face velocity
is satisfied and the work environment
is safe.
The FHC allows for various fume hood
control configurations including sash
position sensing, sidewall face velocity
sensing or hybrid sensing. When
the FHC is utilizing a venturi valve to
control the fume hood exhaust airflow,
the controller measures pressure
drop across the valve allowing for
duct-system pressure alarms and
simplified balancing. Once installed
and commissioned, the FHC is
maintenance-free allowing for reliable
fume hood control and monitoring.
Features
The Fume Hood Controller (FHC) can ensure a safe working environment by
constantly monitoring and adjusting the exhaust to maintain a safe face velocity.
The main control inputs are sash sensors and sidewall sensors. Sash sensors
use a potentiometer attached to the sash to measure the current height. Face
velocity in feet per minute (FPM) is calculated in real time. Sidewall sensors use an
extremely sensitive, low pressure sensor to measure the negative pressure in the
hood compared to the lab space.
• 16 bit – high speed flash based microprocessor with watch dog timer, brown
out reset
• Multi-stage surge protection against voltage spikes on 24 VAC input
• 2 simple connections to sidewall sensors using RJ-12 jacks
• 3 Sash position inputs (10kΩ)
• 2 binary outputs rated at 0.5 amps each, protected with thermal fuse
(RED LED on trip)
• 1 binary output (dry contact)
• 2 analog outputs (0-10 VDC)
• 2 binary inputs
• Pluggable terminal blocks
• Configurable network port for communication on Mnet (High Speed Fume
Hood Network) or BACnet
• 1 potentiometer input
• 1 pressure port input
CAUTION
A higher face velocity is not
always safer. Turbulence in the
fume hood can be created by high
face velocities causing issues with
spillage/blowback.

Fume Hood Location
Considerations
• Ensure supply/exhaust overhead
diffusers/returns are installed away
from fume hood. Direct airflow
running across the ceiling and then
down the face of the fume hood
will greatly affect the SIDEWALL
SENSOR and general performance
of the hood
• Ensure hood is located away from
pedestrian traffic and doors
• Ensure fume hood has all
components installed properly
– such as air foils and sills. Any
missing components can greatly
affect the commissioning of the
hood. Balancing of the face velocity
should not be done if any of these
components are missing.
CAUTION
The location of the fume hood
and overhead diffusers is critical
to proper safety and performance.
These guidelines will ensure the
effectiveness of the fume hood.

Sash Position Sensor (SPS)
Installation & Mounting
The sash sensor can be mounted in
one of four ways. Option A mounts
directly above the sash outside of the
fume hood. Options B and C mount to
the counter weight cable, and Option
D mounts directly in the hood.
Option A) Mount the sash sensor
above the sash.
• Ensure the cable is free from
obstruction along the entire length
of sash movement.
• Ensure that the mounting position
of the end of the cable will not pass
above the sash sensor even at the
maximum sash height.
• Run the sensor cable back to the
FHC mounted on the venturi valve.
Option B) Mount the sash sensor on
the top of the fume hood.
• Ensure the cable is free from
obstruction along the entire length
of sash movement.
• The sensor cable may be attached
directly to the counter weight.
This configuration may be desired
when the sash connects to the
counterweight with a belt and
pulley system.
• Run the sensor cable back to the
FHC mounted on the venturi valve.
Option C) Mount the sash sensor on
the top of the fume hood.
• Ensure the cable clamp does not
pass around a pulley.
• Run the sensor cable back to the
FHC mounted on the venturi valve.
• Ensure the sensor cable travels
parallel to the counter weight cable.

6FHC - Manual |AntecControls.com
Option D) Mount the sash sensor on
the inside wall of the fume hood. This
is the least preferable mounting option,
as the sensor is directly in the exhaust
air stream.
• Ensure that the sensor and cable to
not interfere with the mechanical
operation of the fume hood sash.
• Ensure the sensor is as close to the
sash as possible so that the cable
is completely parallel to the sash in
all positions.
• Raise the sash to the fully open
position (not just the working
height). Screw the metal ring into
the sash. Ensure that the sensor is
mounted higher than the fully open
position of the sash.
• Once mounted, raise and lower the
sash several times to ensure that
the cable is clear of all obstructions
and moves freely with the sash.
• Run the sensor cable back to the
FHC mounted on the venturi valve.
OPTION D
CAUTION
The sash position sensor cable must
be mounted as close to parallel as
possible with the direction of the
sash movement. Any angle can
cause improper sash height readings
and result in poor control.
CAUTION
If only one SPS is required, the
SPS must be wired into the Sash
Position Sensor #1 port on the
FHC.

The fume hood interface will be the main tool used during
setup. It will also be the main display for the hood user once
the hood has been commissioned.
It is recommended to mount the interface at approximately
5 ½’ to 6’ from the floor. This will allow the interface to be at
an appropriate height for use during setup and during normal
operation.
1. Mark the appropriate mounting location for the interface.
CAUTION
There are often disconnect switches and gas/water lines
running in the fume hood. Make sure that the marked
location for the interface does not conflict with any of the
other components that may be installed on/in the fume
hood.
2. Cut approximately a 2”x2” square hole in the front panel
of the fume hood.
3. Remove the backplate from the fume hood interface.
4. Align the backplate with the square hole in the front
panel. Drill two holes to be used for mounting the
backplate.

NETWORKING AND SETUP
11
AntecControls.com |FHC - Manual
Fume Hood Network (FHN)
What is the Fume Hood Network?
The Fume Hood Network (FHN) (also referred to as Mnet)
allows each Fume Hood Controller (FHC) to communicate
with Pace™. By transmitting this information at high speeds,
Pace™ can ensure that the lab will remain negatively or
positively pressurized even as the fume hoods are opened
and closed.
A single Pace™ in the room will act as an access point to
FHN. Typically, the room’s exhaust valve will act as this
connection, as shown below.
Network Addressing
When configuring the Fume Hood Controller, ensure to
follow the addressing scheme below.
On any Fume Hood Network:
• Maximum number of fume hoods = 16
• Addressing must begin at 1 and go sequentially up to 16
• No duplicate addresses
Physical Connection
FHN consists of a 3-wire network architecture (+, -, and
NETCOM) using a daisy-chain connection between each
device on the network segment.
While FHN is a 3-wire network, the Fume Hood Controller
does utilize an RJ45 connection. When connecting FHN
to Pace™, the installer is required to terminate the 3-wire
connection from Pace™ into an RJ45 connection. It is crucial
to use the correct wires when crimping the cable to avoid
network communication errors.
FHN will utilize PIN 1, PIN 2, and PIN 8 for the +, -, and
NETCOM signals respectively. Antec Controls recommends
using the T568B Color Convention (shown below) for RJ45
connections to standardize the PINs that are used.
End of line termination can be enabled through the Fume
Hood Controller on the last Fume Hood in the physical
wiring. A 100 ohm resistor must be used for end of line
termination where FHN is connected to Pace™.
Wiring requirements:
• 3-conductor wire (24 - 26 AWG)
• Characteristic impedance: 100 ohms
• Capacitance between conductors: Less than 30pF per
foot (100pF per meter)
CAUTION
The maximum wire length between each device on the
network segment must be limited to 35 feet

BACnet MS/TP Network
What is BACnet?
If no PACE™ controllers are present in the space, BACnet
MS/TP communication may be used to all the Fume Hood
Controllers to communicate with the building automation
network. BACnet communication allows the end user to
verify fume hoods are operating as expected and allows
them to set up trends to monitor energy consumption,
safety, and any alarms that occur.
BACnet Points
See the FHC - Fume Hood Controller product submittal at
AntecControls.com for the BACnet points list.
Network Addressing
When configuring the Fume Hood Controller, the user needs
to assign the unique identifying address for the room.
On any BACnet MS/TP network:
• MAC Address can be between 0 and 127 and must be
unique to the MS/TP segment
• Device Instance can be between 0 and 4,194,303 and
must be unique to the facility
• Baud Rate can be 9,600, 19,200, 38,400, or 76,800 and
must match that of the Router/System Controller for the
MS/TP segment
Physical Connection
BACnet consists of a 3-wire network architecture. Daisy
chain the +, -, and COM connections of all devices on the
network segment as shown below. The FHC utilizes RJ45
connections for its network connection, see below for the
wire colors required when crimping the RJ45 connection (be
sure to follow the T568B color convention).
When using shielded cable, ground the shield at one end of
the network segment only. Connect the shield of the cable
entering a device to that of the cable exiting the device.
Terminate the MS/TP network segment at each end of
the network segment by connecting a 120 ohm resistor
between the + and - network terminals or by enabling
the EOL Termination function in the FHC. Remove the
termination resistor or disable any network terminations
on all devices when adding devices to an existing network
segment.
Wiring requirements:
• Twisted pair
• Shielded (either foil or braided shields)
• Characteristic impedance: 100 – 130 ohms
• Capacitance between conductors: less than 30pF per
foot (100pF per meter)
TYPICAL BACNET WIRING
CAUTION
When using non-isolated power supplies (i.e. Transformer
secondary common connected to ground), do not reverse
24VAC polarity on any device, as it is critical to the network
health.
For system health and reliability, total MS/TP segment
length should be limited to 1050 ft and a maximum of 32
devices.
NOTE: Ensure End of Line Termination is enabled on the FHC at the physical end of line for the MS/TP segment.

Hybrid Control
This method is an optimized
combination of both sidewall sensor
and sash sensor control. It is the most
effective method of fume hood control
and is recommended in all cases.
Hybrid Control is only available if both a
sidewall sensor and a sash sensor are
connected.

CTRL METHOD: HYBRID A hybrid control method uses both a Sash Position Sensor (SPS) and a Sidewall Sensor (SWS) to control the face velocity.
CTRL METHOD: SASH CTRL A sash control method uses a Sash Position Sensor (SPS) to calculate the required ariflow to maintain face velocity based upon the measured sash
position.
CTRL METHOD: SIDEWALL CTRL A sidewall control method uses a Sidewall Sensor (SWS) to adjust airflow to maintain face velocity based upon the pressure differential between the
fume hood and the space
CTRL METHOD: NO CONTROL Airflow will not be controlled. A sidewall or sash position sensor may still be used to monitor face velocity
FALLBACK CTRL If SW FALLBACK selected, the fallback control method will use the SWS in the event that the primary control method malfunctions. Only an option
when sash control method is selected and there is a SWS detected.
MONITOR METHOD If SASH MONITOR selected, the position of the sash and the current airflow will be used to display the calculated face velocity. If SW MONITOR
selected, the face velocity will be displayed based on the differential pressure measurement provided by the Sidewall Sensor
OCC. SETPOINT Sets the face velocity target of the fume hood in Occupied Mode. The velocity can range from 60 FPM to 150 FPM
DEADBAND The range at which the face velocity target is satisfied. Example: The deadband is set to 10 FPM and the face velocity target is 100 FPM. At any face
velocity between 90 and 110 FPM, the control loop is satisfied and current face velocity will display at 100 FPM. Set the deadband to
CAL MODE for a deadband of 0 FPM.
SETBACKSETPNT Sets the face velocity target when the fume hood is in setback mode. The velocity can be set to 0 FPM or in the range of 60 to 150 FPM. To reach 0
FPM, press and hold the down key.
OFFDAMPERPOS. Off Damper Position sets the actuator position of the airflow device when the fume hood is turned off. Setting this to 0% will be a closed damper
position, setting this to 100% will be a fully open damper position.
MIN CFM Sets the minimum allowable airflow for the fume hood. This is a scheduled value. The airflow can range from 0 to 10000 CFM
MAX CFM Sets the maximum allowable airflow for the fume hood. This is a scheduled value. The airflow can range from 0 to 10000 CFM
SETBACKMINCFM Sets the minimum allowable airflow for the fume hood when in Setback. This is a scheduled value. The airflow can range from 0 to 10000 CFM
OFFREPORT0CFM If set to YES, Airflow will be reported as 0 CFM regardless of current conditions when the Fume Hood is in Off mode.
CTRL/MONITOR: SIDEWALL This menu allows for adjustments to the sidewall sensor (SWS).
SW READ MODE This menu is visible if multiple sidewall sensors are available. Selecting HIGHEST SENSOR will use the highest reading SWS to report face velocity.
LOWEST SENSOR will use the lowest reading SWS to report face velocity. AVG SENSOR will average all SWS readings. SENSOR 1 or 2will provide
only that SWS reading.
FREEZE VALVE Freeze the airflow device at its current position. This setting is used when measuring the face velocity while balancing the fume hood.
SENSOR SCALE Adjust the reading of the SWS by using a multiplying factor. Example: If the SWS is displaying 100 FPM and the balancer’s equipment is displaying 85
FPM, set the sensor scale to 0.850. The range is 0.5 to 2.0.
FACE VELOCITY Read only value displaying the current face velocity that is read by the sidewall sensor including adjustments made by SENSOR SCALE and
SENSOR OFFSET.
SENSOR OFFSET Adjust the reading produced by the sidewall sensor by using an offset. Example, if the SWS is displaying 85 FPM and the blancer’s equipment is reading
100 FPM, set the sensor offset to be 15 FPM. This should be a secondary balancing tool. The range is -20 to 20 FPM
SIDEWALL MENU: ZEROSWSENSOR Zero the SWS. Ensure that both the interior and exterior sensor openings are properly sealed before starting this calibration.
If a SWS is plugged in after initial set-up, it will have to be zeroed before it will be functional.
SIDEWALLMENU: SIDEWALL PID The speed the controller responds to the changes in the SWS reading. PID factors are represented as a single number between 0 and 10 with 0 being
the slowest repsonse and 10 beign the fastest response.
CTRL/MONITOR: SASH This menu allows for adjustments to the sash position sensor (SPS).
MAX HEIGHT Set the maximum height of the sash. This is the fully open position which may be above the working height. The height is the distance measured in the
direction of the SPS movement.
MIN HEIGHT Set the minimum height of the sash in its fully closed position. This position is measured from the bottom of the sash to the work surface. This should
not be measured from the bottom of the sash to the fume hood airfoil.
FULLY OPEN SASH The operator should move the sash to the MAX HEIGHT. Once at the MAX HEIGHT, press OK.
CLOSE SASH The operator should move the sash to the MIN HEIGHT. Once at the MIN HEIGHT, press OK.
SASH WIDTH Set the fixed width of the sash. This is not the width of the fume hood but of the sash.
LINEAR CAL. The airflow provided will be calculated using the sash position and the face velocity target. Flow = Height * Width * Face Velocity
CAL. FROM SW The airflow provided is mapped to the SPS based upon the SWS reading to meet the face velocity target. When selected, the user will be asked to
open the sash to various heights and verify that the face velocity signal is stable at each height. For multiple SPS’s, all sashes need to be moved to the
required position for each stage of the Cal.
CAL. MANUALLY The airflow provided is mapped to the SPS based upon face velocity readings measured by face velocity measuring device to meet the face velocity
target. For multiple SPS’s, all sashes need to be moved to the required position for each stage of the Cal.
SASH SCALE Adjust the airflow provided at a given sash opening position by using a multiplying factor. Example, if the balancer is reading 120 FPM, and the fume
hood is at 100 FPM, set the sash scale to 1.2. The range is 0.5 to 2.0
SASH OFFSET Adjust the airflow provided at a given sash opening position by using an offset. Example, if the sidewall sensor is displaying 85 CFM and the Balancer is
reading 100 FPM, set the Sensor Offset to be 15 FPM. This should be a secondary balancing tool, the sash scale is a more accurate tool. The range is 0
to 20 FPM
CAL VALVE Calibrate the venturi valve. This should be performed any time airflow set points are changed, after an actuator is replaced, after a power failure, or
after clutching and manually moving an actuator
CFM SCALE Adjust the factory calibration of a valve. This function is used when the reported valve airflow does not match a balancers traverse readings when the
valve is operating within design pressure limits. Use the CFM Scale to apply a multiplying factor to the valve airflow. The range is 0.5 to 2.0. NOTE:
Need to Cal Valve after changing this setting.
CFM OFFSET Adjust the factory calibration of a valve. This function is used when the reported airflow valve airflow does not match a balancers traverse readings
when the valve is operating within deign pressure limits. Use the CFM Offset to adjust the airflow by an offset factor. The range is (-10 000) to 10 000
CFM. NOTE: Need to Cal Valve after changing this setting.
