Product Overview
The CW2 Series of air quality sensors for living space is a exible multi-sensor platform for use with BAS controllers
designed to accept 4 to 20mA, 0 to 5Vdc or 0 to 10Vdc outputs. CW2 Series sensors are available with three user
interface options: touchscreen, LCD with three buttons and blank. CO2 and temperature sensors are included with
all CW2 Series air quality sensors. Models with VOC sensors and relative humidity sensors are also available.

CW2 Series Installation Guide
1. Remove the cover from the base at the bottom of the device.
2. Position the sensor base vertically on the wall 1.35 m (4.5 ft.) above the oor with the “UP” arrow facing upward. Locate away
from windows, vents and other sources of draft. If possible, do not mount on an external wall, as this may cause inaccurate
temperature readings.
3. Pull 18 or 22 AWG cable(s) through the hole in the backplate.
4. Mount the backplate onto the wall using the screws provided.
Six screw holes available. Use a minimum of
two for secure mounting.
5. Connect the wires to the screw terminals. Do not over-tighten the screws.

8. Install locking screw to secure cover in closed position.
There are two methods for CO calibration available: 400 ppm baseline calibration and automatic baseline calibration (ABC).
400 ppm Baseline Calibration
400 ppm baseline calibration allows the sensor to be set at 400 ppm. Push and hold the calibration button for 3 to 5 seconds. The
LED will ash green. Once the button is released, calibration is complete and the LED switches o.
Calibration button access hole
LED
Automatic Baseline Calibration (ABC)
The ABC mode addresses the 400 ppm calibration. It allows turning on or o a background correction/recovery mode that will
minimize any calibration error that has been caused by shock during handling and transportation or is caused by a long term shift
in measurement. The ABC algorithm constantly keeps track of the sensor’s lowest reading over a precongured time interval and
slowly corrects for any long-term drift detected as compared to the expected fresh air value of 400 ppm. After initial startup, it is
expected that the sensor reaches specied accuracy after 7 to 21 days.
