The Johnson Controls® CD-Px0xx-00-00 Series duct mount transmitters are designed for the measurement of CO2 and temperature in HVAC applications where demand control ventilation (DCV), fresh air and indoor air quality (IAQ), and rooftop air handling economizer control systems are often required. The CD-P series sensors incorporate the dual-wavelength non-dispersive infrared (NDIR) CO2 sensor, which compensates for aging effects, is highly insensitive to pollution, and offers outstanding long-term stability. The CD-P1000-00-00 transmitter is available with CO2 output only, 0 to 10 V, or 4 to 20 mA, while the CD-P2000 Series offers CO2 and temperature measurement with active or passive outputs. A multiple point CO2 factory adjustment procedure leads to excellent CO2 measurement accuracy over the entire temperature working range.

Features and Benefits
• Adjustable duct probe depth—Permits optimal placement of sensing tip in a duct.
• Support for DCV—Offers potential for 10 to 70% energy savings.
• Single-beam dual-wavelength NDIR CO2 sensor—Is highly insensitive to pollution with outstanding long-term stability.
• Models include CO2 and CO2 + temperature outputs—Reduces installation time and cost.
• 0 to 10 V or passive temperature output—Is suitable for a wider range of applications.

Applications
These compact devices are designed to work:
• in stand-alone mode
• as part of any integrated building automation system (BAS)
• in HVAC applications where DCV, fresh air, or IAQ control strategies are required
