Johnson Controls CD-P1000-00-00U Transmitter

The Johnson Controls CD-P1000-00-00U is a precision duct mount CO2 transmitter engineered for integration into building automation systems to optimize demand-controlled ventilation (DCV). As the direct replacement for the legacy CD-P1000-00-00 model, this updated unit features an aesthetic color change while maintaining reliable NDIR CO2 sensor technology. It provides accurate carbon dioxide monitoring within a range of 0 to 2,000 ppm, outputting a stable 0–10 V or 4–20 mA signal. Designed for HVAC air quality control, the transmitter ensures compliance with ASHRAE standards by managing fresh air intake based on actual occupancy levels rather than fixed schedules. The rugged enclosure is built for the demanding environment of commercial ductwork, offering long-term stability and minimal drift. For contractors, the CD-P1000-00-00U CO2 sensor provides a straightforward installation process and seamless compatibility with Metasys and other third-party BAS controllers.

• Universal Output Compatibility: Supports both 0–10 VDC and 4–20 mA analog signals for easy integration with most HVAC controllers.
• Direct Replacement: Specifically designed to swap into existing footprints of the CD-P1000-00-00, reducing downtime during field upgrades.
• NDIR Technology: Utilizes non-dispersive infrared sensing for high accuracy and resistance to sensor poisoning or degradation.
• Energy Efficiency: Enables precise demand-controlled ventilation, significantly reducing heating and cooling loads by preventing over-ventilation.

Frequently Asked HVACR Questions

How do I wire the CD-P1000-00-00U for 4-20 mA operation?
The unit features dip switches or jumper settings to toggle between voltage and current outputs. Ensure your controller’s input impedance matches the transmitter specifications to prevent signal attenuation.

Is this CO2 transmitter compatible with older Johnson Controls Metasys systems?
Yes, this transmitter provides a standard linear analog signal that is compatible with legacy Metasys systems and modern building management configurations requiring 0–2,000 ppm scaling.

Does this unit require field calibration upon installation?
These units are factory-calibrated; however, for critical applications, verifying the baseline against a handheld CO2 meter after the initial 24-hour burn-in period is recommended for maximum precision.
