Telaire Ventostat 8000 Series Operation & Installation Manual

Troubleshooting
Symptom
• LCD Display is blank after the 2 minute warm-up period (8002 and 8008
models).
Remedy
• Remove the sensor from the wiring plate and check the voltage on pins 1
and 2 of the 2-pin terminal block. The voltage should be: 18-30 VAC RMS or
18-42 VDC.
• Ensure that the sensor pins that connect to the 2-pin terminal block are not
broken, bent, or damaged.
• If the LCD display is still blank after replacing the sensor on the mounting
plate, call Telaire or your distributor/dealer for a return authorization number.
Symptom
• Green light is not illuminated (8001 and 8008 models) after the two minute
warm-up period.
Remedy
• Remove the sensor from the wiring plate and check the voltage on pins 1
and 2 of the 2-pin terminal block. The voltage should be: 18-30 VAC RMS or
18-42 VDC.
• Ensure that the two pins on the sensor that connect to the 2-pin terminal
block are not broken, bent, or damaged.
• If the green light is still not illuminated after replacing the sensor on the
mounting plate, try verifying the sensor operation using the UIP8000
computer interface or checking the output signal on the building automation
system.
• If there is not an output signal, call Telaire or your distributor/dealer for a
return authorization number.
Symptom
• Suspect the sensor is out of calibration.
Remedy
• Compare the sensor reading to a Telaire 7001 hand-held CO
• Take another sensor from the building and replace the suspect sensor to see
if the readings are similar, or
• Connect the sensor outdoors (if possible). The readings should be between
350 and 450 ppm, or
• Connect the sensor to nitrogen gas from a Model 2075 calibration kit. The
reading should be close to zero.
• If the sensor proves to be out of calibration, calibrate the sensor according to
the instructions included in your calibration kit or return the sensor to Telaire
for factory calibration (call for a return authorization number).
Symptom
• Relay does not actuate at the proper setpoint.
Remedy
• Using the LCD menu or the UIP8000 computer interface, verify that the relay
setpoint is correct.
• Return the sensor to normal operating mode, and breathe into the sensor to
raise the ppm value above the relay setpoint.
• If the relay does not actuate at the proper setpoint, call Telaire or your
distributor/dealer for a Return Authorization (RA) number.

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.
Basic Installation of the Mounting Plate and Sensor
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 mounting holes.
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. 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" (current CO readings).
2
5. At this point one of nine preset programs or one custom channel can be
selected for operation. Refer to "Configuring the Sensor."
6. Finish installation by sliding the cover over the menu keys and secure with
the supplied screw.

Sensing Duct CO
Duct-Mounting the 8001B and 8002B
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 8007 and 8008
Install the mounting bracket then install the pitot tube assembly as follows:
Note: The length of the Tygon
tubing is three feet. In order to
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 mechani-
cal or moving devices.
1. To mount the pitot tube, drill one 7/8" hole through the duct.
2. Insert the pitot tube and mark the two remaining holes for the
mounting screws.
3. Punch or drill the two marked holes.
4. Note the direction of airflow in the duct.
5. Note the marking on the pitot tube flange and insert
so that it is properly aligned with the airflow.
6. To ensure an air tight seal, make sure the mounting
surface of the duct is clear of dirt or obstructions. Then, attach the pitot tube
to the duct with sheet metal screws or rivets.
7. On top of the sensor, unscrew the protective caps from the tube connectors.
8. Check the length of the tubing before attaching to the sensor. The tubing
should connect without stretching or pulling. If the length is long enough to
create a loop or bind in the tubing, it should be shortened.
9. To shorten the tubing, remove the connectors that attach to the sensor and
cut the tubing to length.
10.Replace the tubing connectors by using a twisting or screwing motion.

Verify the connection is secure.
Note: If the tubing length has been shortened, be sure the in-line filter is
replaced on the pitot tube connector marked with an "H".
62659-006 09/08/2004 11. Complete the installation by screwing the tube connectors to the input
ports on the sensor. The tubing connectors can be attached to either input
port. It will not affect the performance of the sensor.
