CO2 Sensor ACCESSORY
1.0 OVERVIEW
The CO2 monitor uses a highly accurate and reliable Non-dispersive Infrared (NDIR) with state-
of-the-art digital linearization and temperature compensated circuitry to detect CO2 levels in an
attractive, low profile enclosure for room applications and a duct mount version provide a linear
analog signal output of 4–20 mA, 0–5, or 0–10 VDC and a Normally Open (NO) relay to control
an alarm or ventilation fan in various ways.

DUCT CARBON DIOXIDE TRANSMITTER
CD2DT SERIES
PRODUCT DESCRIPTION
The duct CO2 transmitter uses a highly accurate and
reliable non-dispersive infrared (NDIR) sensor in an
attractive enclosure with a gasketed, hinged cover
for duct applications to monitor CO2 levels. The
sensor uses dual wavelength optics and LTA (long
term adjustment) signal processing technology
to deliver industry leading long term accuracy
and reliability. These features ensure optimum
measurement stability for continual monitoring of
either supply or return air measuring.
Optional features include a resistive temperature
sensor output (with LCD display of temperature in
either °C or °F), a control relay with programmable
setpoint, hysteresis and time delay, and either a
conduit or cable gland connection point.
TYPICAL INSTALLATION
For complete installation and wiring details,
please refer to the product installation
instructions.
The duct type sensor installs on the outside of a
return air duct with the sampling tube inserted into
the duct. Mount the sensor in an easily accessible
location in a straight section of duct at least ve
feet from corners and other items that may cause
disturbances in the air ow. Avoid areas with
vibrations or rapid temperature changes.
The enclosure provides mounting tabs for ease of
installation.

In this example, the CO2 Controller turns the ERV on at speed set by potentiometer(s) when CO2
level exceeds CO2 Controller Relay setting. EV450 Circuit Board shown with one potentiometer.
HE1X and HE1.5 Circuit Boards have two potentiometers.
In this example, the ERV does not run while unoccupied, set by timer. During occupancy,
ERV runs at variable Speed. CO2 Controller sets speed based on CO2 levels. Remove the
potentiometer(s) by cutting the wires at the potentiometer. Cap the orange and purple wires
from the potentiometer with wire nuts. EV450 Circuit Board shown with one potentiometer.
HE1X and HE1.5 Circuit Board has two potentiometers and the cut wires can be wired in parallel
back to the CO2 Controller.

About RenewAire
For over 30 years, RenewAire has been a pioneer in enhancing indoor air quality (IAQ)
in commercial and residential buildings of every size.This is achieved while maximizing
sustainability through our fifth-generation, static-plate, enthalpic-core Energy Recovery
Ventilators (ERVs) that optimize energy efficiency, lower capital costs via load reduction and
decrease operational expenses by minimizing equipment needs, resulting in significant energy
savings. Our ERVs are competitively priced, simple to install, easy to use and maintain and have
a quick payback. They also enjoy the industry’s best warranty with the lowest claims due to
long-term reliability derived from innovative design practices, expert workmanship and Quick
Response Manufacturing (QRM).
As the pioneer of static-plate core technology in North America, RenewAire is the largest ERV
producer in the USA. We’re committed to sustainable manufacturing and lessening our
environmental footprint, and to that end our Waunakee, WI plant is 100% powered by wind
turbines. The facility is also one of the few buildings worldwide to be LEED® Gold and Green
Globes certified, as well as having achieved ENERGY STAR Building status. In 2010, RenewAire
joined the Soler & Palau (S&P) Ventilation Group in order to provide direct access to the latest in
energy-efficient air-moving technologies. For more information, visit: renewaire.com
