Johnson Controls offers a full line of Carbon Dioxide (CO

) transmitters for measuring and transmitting CO2

levels, ranging from 0 to 2,000 parts per million (ppm), within Heating, Ventilating, and Air Conditioni ng (HVAC) CO

applications include Demand Control Ventilation (DCV), fresh air and Indoor Air Quality (IAQ), and rooftop air handling Economizer controls systems.

These compact, wall mounted devices output 0 to 10 V (default), 0 to 20 mA, or 4 to 20 mA signals and feature analog temperature outputs, relay outputs, and/or a digital display as (optional) features. They are designed to work:

• in standalone mode

Product Overview

This transmitter uses a completely new CO2 sensing technology. The silicon based CARBOCAP® sensor

provides stability and reliability. The CARBOCAP sensor operates in accordance with

the single beam, dual wavelength method. This patented sensor has unique reference measurement capabilities, offering excellent stability over both time and temperature. The monolithic Fabry-Perot Interferometer (FPI) chip uses the optical, mechanical, and electronic properties of silicon at the same time.

The transmitter is factory set to measure CO to 2,000 ppm. It requires a Class 2, 24 VDC/V AC power

source and generates an output signal proportional to the CO

level detected. One simple wire to a screw

terminal and a jumper on the Printed Circuit Board (PCB) combine to select the analog output signal from the following options:

• 0 to 20 mA

• 4 to 20 mA

• 0 to 10 V (default) IMPORTANT: The CD-Wxx-00-0 CO

is intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the transmitter could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the transmitter.

Transmitter

Calibration

Johnson Controls® CO2 transmitters are calibrated using certified gases for the following:

• output signal (0 to 10 V) proportional to CO

concentration (0 to 2,000 ppm)

• altitude range of 0 to 2,000 ft (0 to 600 m) above sea level without compensation

• relay output trigger point set for 1,000 ppm (in models featuring the optional relay output)

CARBOCAP Technology

Johnson Controls is licensed to integrate the new, silicon based CARBOCAP CO

sensor into HVAC or

Building Automation Systems. This sensor has several advantages: high accuracy, excellent stability, negligible temperature dependence, and ease of installation.

The structure of the diffusion aspirated, single-beam dual-wavelength sensor is remarkably simple. It consists of an Infrared (IR) source, a sample cell, a tunable interference filter, and an IR detector. The tunable interference filter enables measurements at two wavelengths. As a result, references are measured accurately, without the typically broad tolerances inherent in dual-beam sensors.

Dust, water vapor, and most chemicals do not affect the measurement accuracy of the sensor. No special software compensation patches are required, and the device requires no maintenance.

Versatile Transmitter

Designed for use with a standard U.S. wallbox or mounting directly to a wallboard surface, the CO

transmitter generates considerable savings in installation, operation, and maintenance with no recalibration costs. Johnson Controls includes a Drywall Spring-Clip Mounting Kit with each unit.

Johnson Controls® CO2 transmitters, when used with BAS/Economizer controllers (featuring DCV

strategies), can generate energy savings ranging up to:

• 20 to 40% in office buildings

• 20 to 60% in restaurants/light retail facilities

• 10 to 70% in educational/business settings

Optional Features

Analog Temperature Module

For applications requiring measurements and outputs for both CO

transmitter. Th is model includes an analog temperature module that plugs into the main PCB and has an active temperature output, linear from 0 to 10 VDC for 32 to 122

and temperature, order the CD-W A0-00-0

°F (0 to 50°C).

Dimensions

See Figure 2 and Figure 3 for CO2 transmitter and mounting flange dimensions.

Relay Module

Order the CD-WR0-00-0 transmitter for applications where On/Off ventilation or fan control is required to provide fresh air. This model includes a relay output module that plugs into the main PCB offering a 30 V,

0.5A Class 2 output with configurable On and Off trip

points. Default On is 1,000 ppm, and default Off is 950 ppm.

Note: To redefine the relay On and Off trip points to suit the application, use the ACC-CD-S Relay Setpoint Software.

Relay and Display Module

For applications where the display of the measured CO

level and a relay output and relay On notification

are required, order the CD-WRD-00-0. This module contains a relay and a digital display. The unit plugs into the transmitter PCB. The display includes a 4-digit display and a Light-Emitting Diode (LED), which indicates when the relay is On.

Note: To redefine the relay On and Off trip points to suit the application, use the ACC-CD-S Relay Setpoint Software.
