Description
Overview
The Johnson Controls CD-WA0-00-2U is a wall-mount combination CO2 and temperature transmitter engineered for reliable indoor air quality (IAQ) monitoring in commercial and light-industrial HVAC applications. Designed for easy installation on standard wall surfaces, this dual-function transmitter delivers accurate carbon dioxide concentration and ambient temperature readings to building automation systems (BAS), demand-controlled ventilation (DCV) controllers, and energy management systems.
Key Features
- Dual-sensing capability: simultaneous CO2 concentration and temperature measurement in a single wall-mount enclosure
- Designed for demand-controlled ventilation (DCV) applications to optimize fresh-air delivery and reduce energy consumption
- Wall-mount form factor for straightforward installation in occupied spaces such as offices, classrooms, conference rooms, and retail environments
- Compatible with Johnson Controls building automation and HVAC control systems
- Compact, low-profile housing blends with standard commercial interior décor
- Reliable NDIR (Non-Dispersive Infrared) CO2 sensing technology for long-term accuracy and stability
Applications
- Demand-controlled ventilation in commercial buildings
- Building automation and energy management systems
- Offices, classrooms, conference rooms, and retail spaces
- HVAC air-handling unit (AHU) control and optimization
Why Choose the CD-WA0-00-2U
Monitoring both CO2 levels and temperature from a single device simplifies wiring, reduces installation time, and lowers overall system cost. By integrating this transmitter into a DCV strategy, building operators can ensure occupant comfort, maintain healthy indoor air quality, and achieve measurable energy savings by ventilating only as needed — rather than at a fixed, often excessive rate.
