Sash, Sidewall & Hybrid Configuration
Control Settings
No Control – Monitor Only
This method disables all control. The device will only monitor the face velocity of the fume
hood / cabinet using a Sash Position Sensor and/or a Sidewall Velocity Sensor, but will not
change its airflow or face velocity.
Sash Position 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 Face Velocity Control
This method measures the face velocity over the sash opening by measuring the pressure
inside the fume hood. This method will control face velocity.
Hybrid Control
This method is an optimized combination of both sidewall face velocity control and sash
position 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 velocity sensor and a sash
position sensor are connected.

Room Information Network (RIN)
What is the Room Information Network?
The Antec Controls Pace™ and Cava™ operate on a
distributed network called the Room Information Network
(RIN). Together, the Pace™ controllers operating in the
room will work to control room levels functions such as
temperature control, room occupancy, and room
pressurization. When used with Cava™, the fume hood
flows, face velocities, and status will be reported to the
room level controllers to ensure all room demands for
safety are being met.
Antec Toolbox also uses RIN for room level and fume hood
configuration. The user will connect to RIN to communicate
with each Pace™ and Cava™ to configure their
functionality.
Network Addressing
All Cava™ devices will come from the factory with
predefined MAC addresses. If a Fume Hood Valve Module
(FVM) is connected during Cava™ setup, the device will
populate with a unique name based on the valve tag in the
FVM’s linestring. If no FVM is connected, or a different
naming convention is required, the name is customizable
from the settings menu.
Physical Connection
RIN consists of a 4-wire network architecture (RX-, RX+,
TX-, TX+) using a daisy-chain connection between each
device on the network segment. A RIN segment has a limit
of:
•24 total RIN devices (Pace™ and Cava™)
•16 Cava™ devices
•A maximum length of 150 feet (45 meters)
between each device.
Users will require an Ethernet Port or a USB-A to Ethernet
dongle to connect a laptop to RIN for configuration.
Wiring Requirements
Refer to your Antec Controls Wiring Diagram Package for
typical wiring requirements and recommendations.

Controller Area Network (CANbus)
What is the Controller Area Network?
The Controller Area Network (CANbus) is a communication
protocol that allows the Fume Hood Valve Module (FVM)
and the Sidewall Velocity Sensor (SVS) to communicate
with Cava™. By transmitting data from the SVS to Cava™
at high speeds and relaying changes to the FVM, Cava™
can ensure that the fume hood is always in safe operating
conditions.
Network Addressing
CANbus devices will come from the factory with
predefined MAC addresses. No addressing on-site is
required.
Physical Connection
CANbus consists of a 3-wire network architecture. Daisy
chain the CANH, CANL, and COM connections of all
devices on the network as shown below. A CANbus
segment has a limit of:
•3 Sidewall Velocity Sensors (SVS)
•1 Fume Hood Valve Module (FVM)
•A maximum length of 650 feet (200 meters) for the
whole segment
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 network at the end of line CANbus device by
connecting a 120 ohm resistor between the CANH and
CANL network terminals. The network may fail to function
without the 120 ohm resistors in place. Remove the
termination resistor when adding devices to an existing
network and re-install it on the new end of line device.
NOTE: Cava™ has a built-in end of line resistor for CANbus
and must be an end of line device.
Wiring Requirements
Refer to your Antec Controls Wiring Diagram Package for
typical wiring requirements and recommendations.
Typical CAN Wiring
NOTE:Installer must use a 120 ohm resistor at the CANbus end of line termination.
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.
CAUTION

CAVA - MANUAL
7 | CAVA – Manual | AntecControls.com
BACnet MS/TP Network
NOTE: BACnet is only used on Cava™ when it does not
have a RIN connection to a Pace™ controller in the room.
What is BACnet?
BACnet MS/TP is a communication protocol for
communication between Cava™ and the building
automation network. BACnet communication allows the
end user to verify rooms and fume hoods are operating as
expected and allows them to set up trends to monitor
safety, and any alarms that occur.
If no Pace™ controllers are present in the space, a single
Cava™ in the room can act as the access point to BACnet.
All of the fume hood’s information transmits through this
one Cava™ to the network.
Network Addressing
When configuring Cava™, 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.
BACnet Points
See Cava™ Product Submittal at AntecControls.com for
BACnet Points List.
Physical Connection
BACnet consists of a 3-wire network architecture. Daisy
chain the +, -, and COM connections of all devices on the
network segment. A BACnet MS/TP segment has a limit
of:
•Maximum of 32 devices
•Maximum length of 1050 feet (320 meters) for the
whole segment
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 – terminals. Remove the termination
resistor or disable any network terminations on all devices
when adding devices to an existing network segment.
Wiring Requirements
Refer to your Antec Controls Wiring Diagram Package for
typical wiring requirements and recommendations.

Sash Position Sensor (SPS)
The Sash Position Sensor (SPS) reports the open area of the fume hood by
measuring the sash location. Cava™ uses the SPS measurement to adjust the
exhaust airflow based upon the measured sash opening. The SPS contains a long-
life potentiometer (over 250,000 cycles) and is constructed using a stainless-steel
cable for stability and a thick plastic cover for protection against airborne chemical
agents.
See the SPS product submittal on AntecControls.com for Specifications,
Dimensions, and Wiring.
Mechanical Installation
The SPS can be mounted in one of four ways. Options A mounts to the counterweight system, Option B mounts directly above
the sash outside of the fume hood, Option C also mounts to the counterweight system, and Option D mounts directly in the
hood.
Option A
Mount the SPS on the top of the fume hood.
STEP 1
Ensure the cable clamp does not pass around a pulley.
STEP 2
Run the sensor cable back to the CAVA mounted on the front of the fume hood and connect it
to a Universal Input (see Electrical Installation section).
STEP 3
Ensure the sensor cable travels parallel to the counterweight cable.
Option B
Mount the SPS above the sash.
STEP 1
Ensure the cable is free from obstruction along the entire length of sash movement.
STEP 2
Ensure that the mounting position of the end of the cable will not pass above the SPS even at
the maximum sash height.
STEP 3
Run the sensor cable back to the CAVA mounted on the front of the fume hood and connect it
to a Universal Input (see Electrical Installation section).
The Sash Position Sensor cable must be mounted as close to parallel as
possible with the direction of the sash movement.
CAUTION

CAVA - MANUAL
14 | CAVA – Manual | AntecControls.com
Option C
Mount the SPS on the top of the fume hood.
STEP 1
Ensure the cable is free from obstruction along the entire length of sash movement.
STEP 2
The sensor cable may be attached directly to the counterweight. This configuration may be
desired when the sash connects to the counterweight with a belt and pulley system.
STEP 3
Run the sensor cable back to the CAVA mounted on the front of the fume hood and connect it
to a Universal Input (see Electrical Installation section).
Option D
Mount the SPS 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.
STEP 1
Ensure that the sensor and cable do not interfere with the mechanical operation of the fume
hood sash.
STEP 2
Ensure the sensor is as close to the sash as possible so that the cable is completely parallel to
the sash in all positions.
STEP 3
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.
STEP 4
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.
STEP 5
Run the sensor cable back to the CAVA mounted on the front of the fume hood and connect it
to a Universal Input (see Electrical Installation section).

CAVA - MANUAL
15 | CAVA – Manual | AntecControls.com
Sidewall Velocity Sensor (SVS)
The Sidewall Velocity Sensor (SVS) reports face velocity to Cava™ by measuring
the differential pressure between the fume hood and the laboratory. Cava™ uses
the SVS measurement to adjust the exhaust to meet the required face velocity. The
SVS consists of multiple components:
•Sidewall Velocity Sensor (SVS)
•1’ x 3.5” 3M Dual Lock Fastener
•Two brass bulkheads with vent screws
•Two 1.5-foot lengths of high-pressure tubing
See the SVS product submittal on AntecControls.com for Specifications,
Dimensions, and Wiring.
Mechanical Installation
The SVS can be mounted in one of three locations. Option A mounts on top of the fume hood, Option B mounts in the side
panelling (chase) of the fume hood, and Option C mounts in the front panelling of the fume hood.
Mounting options may be limited by tubing length and vent screw locations. It is recommended to select the mounting location
which minimizes tubing length, and to keep in mind the following considerations when selecting a location.
Option A
Mount the SVS on top of the fume hood.
•Tubing runs over the top of the fume hood and down the side panelling (chase) and
should not exceed 2 feet.
•Must ensure tubing and wiring do not interfere with the mechanical operation of the
fume hood sash.
Option B
Mount the SVS in the side panelling (chase) of the fume hood.
•Exterior wall of chase is often removable for maintenance. If sensor is mounted to
this wall, it will need to be disconnected for removal.
•Ideal mounting location is on interior wall above the inside wall access panel.
Option C
Mount the SVS in the front panelling of the fume hood.
•Tubing runs from front panelling to side panelling, which may require passthrough
holes to be drilled depending on fume hood design.

CAVA - MANUAL
16 | CAVA – Manual | AntecControls.com
Regardless of where the SVS is mounted, the following steps outline how to install the SVS components.
STEP 1
With the sash in the fully open position, drill a 5/16” hole 5” above and 5” inward from the
base of the sash.
STEP 2
Drill a 5/16” hole on the front of the fume hood on the same side as the first hole.
STEP 3
Mount the brass bulkheads to the fume hood through the holes.
STEP 4
Select one of the three mounting options on the previous page for the SVS and mount using
one of the two methods outlined below:
For 3M Dual Lock Fastener mounting (recommended), clean the mounting surface and
the back of the sensor with a cloth or IPA. Wait 5 minutes for IPA to evaporate if used. At
room temperature, peel backing from one side of the 3M fastener and apply it to the back of
the sensor. Peel backing from opposite side of the 3M fastener and firmly press the SVS and
3M fastener onto the mounting surface for 30 seconds.
For screw mounting, place sensor in desired location and mark the three mounting hole
locations on the fume hood. Drill three 1/8” pilot holes in the appropriate locations on the
fume hood. Mount sensor using three #8 x 5/16 in. screws.
STEP 5
Use the high-pressure tubing to connect the outer brass bulkhead to the high-pressure port
of the sensor. Do the same to connect the inner brass bulkhead to the low-pressure port of
the sensor.
Mounting position is critical to ensure the accuracy of the SVS.
Ensure that there are no sharp bends or kinks in the tubing during
the installation. Improper installation will cause failure of the SVS.
