FUME HOOD CONTROLLER
INTRODUCTION

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.

CAUTION
The FHC is factory calibrated and
mounted on the valve with which
it was ordered. Only electrical
installation is required.
Ensure the valve is facing the
correct direction and is mounted in
the correct orientation (vertical or
horizontal).

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.

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.

Sidewall Sensor (SWS)
Installation & Mounting
• The Sidewall Sensor consists of
multiple components: The Sidewall
Sensor, two hollowed bolts, a
male brass pressure port, and kink
resistant tubing.
• With the sash in the fully open
position, drill a 5/16” hole 5”
above and 5” inward from the
base of the sash. Mount the
Sidewall Sensor behind the fume
hood wall, in the fume hood plenum
using one of the hollow bolts.
• To mount the exterior hollow bolt,
drill a 5/16” hole on the front of
the fume hood, no more than 12”
away from the Sidewall Sensor.
• Attach the provided male brass
pressure port to the exterior hollow
bolt.
• Use the kink-resistant tubing to
attach the brass pressure port from
the SWS to the brass pressure port
on the exterior hollow bolt.
• Attach the sensor cable to the SWS
and run the cable back to the FHC
mounted on the venturi valve.

CAUTION
Mounting position is critical to
ensure the accuracy of the SWS.
Ensure that there are no sharp
bends or kinks in the tubing during
the installation. Improper installation
will cause failure of the SWS.
CAUTION
If only one SWS is required, the
SWS must be wired into the
Sidewall Sensor #1 port on the
FHC.
