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

Installation
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 draf t. 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.
Five screwholes available; use a minimum
of two for secure m ounting.
