FUME HOOD CONTROLLER
SECTION 1 - INTRODUCTION
Product Overview
Fume Hood Controller (FHC) Features
Laboratory fume hoods serve as
ventilation systems that efficiently
exhaust chemical vapors, mist, and
fumes. Fume hoods also provide a
barrier protecting occupants from
certain reactions, spills, and even fires.
In most cases special fans exhaust the
fumes outside, which greatly dilute their
concentration and reduce their harmful
effects. In some cases a specialized
scrubber is also required to remove the
vapors from the exhaust air.
The Fume Hood Controller can ensure a safe working environment by constantly
monitoring and adjusting the exhaust to maintain a correct 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 with the lab space.
Fume hoods require constant exhaust
airflow to ensure that none of the air
entering the fume hood ever escapes
back into the laboratory space. This
ensures the safety of the user and of
any other occupants of the room or
building. The exhaust airflow, measured
in cubic feet per minute (CFM), creates
a face velocity across the sash opening.
This is the industry standard measure
of fume hood safety. Typically the
face velocity of a fume hood must be
between 80 – 100 feet per minute
(FPM), but this can vary based on local
codes or the fume hood design. It is
important to note the required face
velocity for the hood you are using.

CAUTION
A higher face velocity is not always
safer. Too high a face velocity can
cause turbulence within the fume hood,
which can cause 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.
FUME HOOD LOCATION CONSIDERATION
DIFFUSER
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 and

& Mounting
•
Ensure the sash is in the fully open
position (not just to working height)
•
Inside the fume hood, with the
sash in the fully open position,
drill a 5/16” hole 5” above and 5”
inward from the base of the sash in
the fully open position. (Not just the
working height.)
•
Drill a second 5/16” hole on the
front of the fume hood near the
PSWS. The second hole must be
no more than 12” from the SWS.
•
Using the male brass pressure port
provided, attach one hollowed bolt
to the front of the fume hood so
that the rounded side faces out.
Attach the second hallowed bolt
to the inside of the fume hood,
securing the PSWS.
•
Use the kink-resistant tubing to
attach the brass pressure port from
the SWS to the brass pressure port
that was just mounted.

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 onto
the sash. Ensure that the point of

Wiring Diagram
Ensure proper voltage is available for the FHC transformer
in the enclosure. Double check all labels and wiring before
applying high voltage.
CAUTION
The FHC is a 24 VAC low voltage controller. Do not apply any
voltage above 24 VAC to controller.
1. Ensure disconnect switch is off. Route high voltage line to
L1/L2(N) terminal block using knockout/cable clamp
(by others).
3. Connect AO1 terminal block space to the damper
actuator on the exhaust duct of the unit.
4. Connect the sash sensor to the first Sash Position Sensor
location on the FHC.
5. Connect green RJ12 (telephone type 6 position) cable
to jack labeled Sidewall Sensor 1 on FHC. Connect the
other end with the black (locking) connector into Sidewall
Sensor 1. Ensure cable is not twisted, kinked or pinched
during installation. The green LED above Sidewall Sensor
1 on the FHC will be green when powered up and
functioning properly.
2. Connect blue RJ-45 (network type 8 position) plenumrated cable to jack labeled Interface on the FHC. Connect
the other end to the back of the FHI mounted on the side
of the fume hood.

Sidewall Sensor Control
This method measures the face velocity
through the fume hood by measuring
the pressure within the unit from the
sidewall sensor. This method will control
face velocity. Refer to Section 3A for
configuration.
Sash Sensor Control
This method calculates the face velocity
using the dimensions of the fume hood
opening and the current CFM. This
method will control face velocity. Refer
to Section 3A for configuration.
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. Refer
to Section 3D for configuration.
This should only be chosen if both a
sidewall sensor and a sash sensor
are connected.

CONTROL METHOD
SIDEWALL CTRL
FALLBACK CTRL
NO FALLBACK
Sash Sensor Control: This method calculates the face velocity using the dimensions of the fume hood opening and the current CFM. This method
will control face velocity.
Sidewall Sensor Control: This method measures the face velocity through the fume hood by measuring the pressure within the unit from the
sidewall sensor. This method will control face velocity.
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.
Provides a selection of fallback control methods.
This is the type of control the fume hood will use if the primary control method fails.
Sash Sensor Control: This method calculates the face velocity using the dimensions of the fume hood opening and the current CFM. This method
will control face velocity.
Provides a selection of monitor methods. This is how the face velocity of the fume hood is monitored and displayed.
MONITOR METHOD

SASHCTRLMETHOD
LINEAR CAL.
Sash Sensor Monitoring: The face velocity is monitored and displayed using the position of the sash and by calculating the open space area of the
fume hood.
Sidewall Sensor Monitoring: The face velocity is monitored and displayed using the Sidewall sensors. The Sidewall sensors calculates the face
velocity by measuring the difference in pressure between the outside of the fume hood and the inside work area of the fume hood.
Choose the default face velocity set point when the fume hood is occupied.
Sets the sensitivity of the FHC; a lower dead-band creates a higher sensitivity.
This is the minimum/maximum allowable deviation in face velocity before the FHC will make adjustments to the valve.
Choose a method to calibrate the sash you wish to calibrate. Linear, Cal Manually, or Cal from SW.
