Introduction
®
The GE Telaire Ventostat
8001/
8002 carbon dioxide (CO
) sensors and
2
controllers are designed for Demand
Controlled Ventilation (DCV) in
buildings. This approach, using CO
an indicator of occupancy, allows
ventilation based on actual occupancy
while still maintaining ASHARE
recommended per-person ventilation
rates. Over ventilation of buildings can
be reduced, energy can be saved, and
quality can be optimized.
The optional black case (PN 8001B and
PN 8002B) is UL94-V5 rated, making
these models suitable for mounting
directly inside the ductwork. Typical
®
applications for Ventostat
8001/8002 series include office buildings,
conference rooms, schools, retail stores, restaurants, gymnasiums, and
movie theatres.
Installing the Sensor
Use of cellular telephones or radio transceivers within two (2) feet of the
sensor during calibration process could cause sensor interference,
calibration errors and affect sensor accuracy. Please refrain from using
these devices during sensor calibration.
Install the mounting plate and sensor as follows:
1. Prepare for installation by using the mounting holes configured for
US or European junction boxes.
2. Use the mounting plate as a template to mark the mounting holes.
See Figure 1, View A below.

3. Secure the mounting plate to the wall or junction box and make
necessary wire connections.
4. Mount the controller on the base by aligning the top clips and then
securing to the bottom clips, as shown in Figure 1, View B above. A
"snap" sound will indicate that the sensor is secure. The sensor will
now have power. A 2 minute warm-up will take place. After 2
minutes, the sensor will stabilize and display the "Normal Mode"

5. At this point one of nine preset programs or one custom channel can
be selected for operation. See the section "Configuring the Sensor"
on page 3.
6. Finish installation by sliding the cover over the menu keys and
secure with the supplied screw.
Mounting the Sensor into the Duct
The 8001B and 8002B have the UL94-V5 rated black case and are
specifically designed for mounting inside the return air ductwork. When
mounting these products inside the ductwork, seal the hole around the
wires and leave the duct insulation in place to prevent condensation
which may damage the sensor.
Pitot Tube Installation for the
8001 and 8002
Install the mounting bracket, then install the pitot tube assembly as
follows:
Note:
The length of the Tygon
maintain optimum accuracy, the tubing should not be
lengthened. If the sensor is mounted closer than three
feet, the excess tubing should be shortened to avoid
interference with mechanical or moving devices.
1. To mount the pitot tube, drill one 7/8" hole through the duct as
shown in Figure 2 below.
