Description
The ACI 144220 is a professional-grade carbon dioxide (CO2) sensor engineered for building automation and HVAC control applications. Designed to monitor indoor air quality with precision, it delivers reliable CO2 concentration readings across a 0–2000 ppm measurement range and provides dual analog output signals — 0–10 VDC and 4–20 mA — for seamless integration with virtually any building automation system (BAS) or direct digital control (DDC) platform.
Key Features
- CO2 measurement range: 0–2000 ppm (0–2 kppm)
- Dual analog outputs: 0–10 VDC and 4–20 mA
- Compatible with a wide range of BAS and DDC controllers
- Supports demand-controlled ventilation (DCV) strategies
- Suitable for commercial and light industrial indoor environments
- Compact design for straightforward wall or duct installation
Application
The ACI 144220 is ideal for demand-controlled ventilation applications where maintaining healthy indoor CO2 levels is critical. By continuously monitoring CO2 concentrations, the sensor enables HVAC systems to adjust fresh air intake dynamically — improving occupant comfort, reducing energy waste, and supporting compliance with ASHRAE 62.1 ventilation standards.
