Product Overview
CW Series wall mount CO2sensors measure the levels of CO2, RH (if equipped), and temperature (if equipped)
of air inside a duct. The CO2sensor operates within accuracy specications for an interval of ve years and can
be eld calibrated. The temperature element is warranted to meet accuracy specications for a period of ve
years. RH equipped models feature a replaceable HS Series humidity element that is warranted to meet accuracy
specications for a period of one year. To maintain accuracy, all vents must remain clear and free of dust, debris,
etc.

1. Remove the cover by pressing the tab at at the top
of the sensor while pulling outward from the
top of the cover.
2. Remove the backplate by unfastening the sensor
from the bottom of the backplate and pivoting
the sensor outward.
3. Punch out desired wire openings in the backplate.
4. Position the sensor vertically on the wall, 4-1/2 feet
above the oor. Locate away from windows, vents,
and other sources of draft. If possible, do not mount
on an external wall, as this might cause inaccurate
temperature readings.
5. Mount the backplate onto the wall using
the screws provided.
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
All optional connector
blocks are shown here for
clarity.
Five screwholes available; use a minimum
of two for secure mounting.

ABC Calibration
Algorithm
10. Programmable override button
11. Programmable setpoint slider
ABC (Automatic Baseline Calibration) is a patented self-calibration feature that automatically adjusts the CO2sensor to
compensate for drift. When ABC is enabled, the sensor records the lowest reading within every 24-hour interval and compares
these values over a running 7-day or 28-day period. If a statistically signicant amount of drift is detected, the ABC applies an
automatic correction factor. This enables the sensor to operate within specications for the 5-year calibration interval.
ON POSITION. Recommended Setting. Use the ON setting for applications where the building is unoccupied within a 24-hour
timeframe.
LOW POSITION. Use the LOW setting for buildings occupied 24 hours a day.
OFF POSITION. Not Recommended.
NOTE: After changing the ABC settings, power cycle the unit for changes to take eect.
To set the ABC mode for CWL models, refer to the Conguration section of this document.
To set the ABC mode for CWE models, position the ABC jumper as shown:

Output Scaling CO2- Carbon Dioxide Sensor
Output scaling: 0 to 2000 ppm
CO2PPM 0 to 5 V Output 0 to 10 V Output mA Output
Outside 30 to 500 0.75 to 1.25 1.5 to 2.5 6.4 to 8
Over Ventilated Under 600 Under 1.5 Under 3 Under 8.8
Ideal Ventilation 600 to 900 1.5 to 2.25 3 to 4.5 8.8 to 11.2
Under Ventilated Over 900 Over 2.25 Over 4.5 Over 11.2
RH - Relative Humidity Sensor
Output scaling: 0 to 100%
T - Temperature Transmitter
Output scaling: 10° to 35°C (50° to 95°F)
To determine temperature from output reading:
1. Compute Total Span from Temperature Range:
Maximum range - Minimum range = Total span
ex. 10° to 35°C range: 35 - 10 = 25 Total span
2. Compute Output % of Span from Reading:
(Reading - Minimum Output) / (Maximum output - Minimum output)
ex. 11.10 mA reading on 4-20 mA output: (11.10-4) / (20-4) = 7.10 / 16 = 0.444 = 44.4%
ex. 4.44v reading on 0-10 V output: (4.44-0) / (10-0) = 4.44 / 10 = 0.444 = 44.4%
3. Compute Temperature:
(Total span x Output % of Span) + Minimum range
ex. 44.4% Output, Total Span = 45, range = 50/95: (0.444 x 45) + 50 = 20 + 50 = 70°
Example outputs for selected temperatures:
Temperature 4 to 20 mA 0 to 10 V 0 to 5 V
65 9.33 mA 3.33 V 1.67 V
70 11.10 mA 4.44 V 2.22 V
75 12.89 mA 5.56 V 2.78 V

*NOTE: This product is factory calibrated. The typical CO2
sensor calibration interval is 5 years, depending on specic site
installation factors. As of the date of this document, compliance
with ANSI/ASHRAE 62-2001 requires minimum on-site accuracy
verication intervals of 6 months or per the building operation
and maintenance manual. Verify accuracy using a comparison
to a known reference or the CO2gas calibration kit available
from Veris Industries as AA01.
WARNING: CO2sensor calibration requires gas calibration kit.
Performing calibration without gas kit or at an incorrect gas
ow rate will cause erroneous readings.
