Johnson Controls CD-WA0-00-2 Transmitter

The Johnson Controls CD-WA0-00-2 Transmitter is a high-precision, wall-mount solution designed for critical Demand Control Ventilation (DCV) and Indoor Air Quality (IAQ) monitoring. This professional-grade unit features an integrated CO2 sensor and a dedicated analog temperature output, facilitating efficient climate control in commercial buildings. Utilizing patented CARBOCAP dual-wavelength technology, the transmitter achieves superior long-term stability by compensating for light-source drift, which is a common failure point in standard NDIR sensors. It operates on a 24 VAC/VDC power supply and provides a standard 0-2000 PPM CO2 measurement range with a rapid 1-minute response time. Engineered as the direct replacement for the legacy CD-WR0-00-0, the CD-WA0-00-2 integrates seamlessly into existing Metasys environments or any third-party Building Automation System (BAS). Its robust construction supports an operating range of 23-113°F and 0-85% non-condensing humidity, making it the standard choice for contractors focused on energy efficiency and precise fresh air regulation.

• CARBOCAP Technology: Employs a single-beam design that provides high accuracy and remains stable without frequent field calibration.
• Direct Compatibility: Engineered as a drop-in replacement for CD-WR0-00-0, ensuring zero downtime during system upgrades.
• Dual Output Functionality: Simultaneously monitors carbon dioxide levels and room temperature through a single wall-mount interface.
• Advanced Signal Processing: Features altitude compensation and a stable infrared reference to prevent false readings in varied environments.

Common Questions:

How does this transmitter improve HVAC energy efficiency? By providing accurate CO2 data for Demand Control Ventilation, the system only introduces outdoor air when needed, significantly reducing heating and cooling loads.

Can the CD-WA0-00-2 replace the CD-WR0-00-0 model? Yes, this unit is the designated successor. Ensure your controller is configured for an analog temperature signal rather than a relay switch if moving from the older "R" series.

What maintenance is required for the CARBOCAP sensor? These units are designed for long-term use with minimal drift. Technicians should verify that the top and bottom vents remain clear of dust to maintain the 1-minute response time.
