As the direct replacement for the legacy CWE model, this unit features advanced \u003cstrong\u003edual-beam NDIR technology\u003c\/strong\u003e to ensure long-term stability and eliminate the need for manual calibration in standard environments. It provides field-selectable \u003cstrong\u003eanalog output CO2 sensor\u003c\/strong\u003e signals, including 4-20mA, 0-5V, or 0-10V, allowing for seamless integration with a wide variety of controllers. Designed with a sleek, matte white ABS enclosure, it functions within a 0-50°C operating range and delivers a fast response time of ?75 seconds for 90% step changes. This \u003cstrong\u003e2-wire CO2 wall sensor\u003c\/strong\u003e minimizes installation labor with large screw terminals and a low 20mA operating current, making it a reliable solution for maintaining indoor air quality and optimizing energy efficiency in schools, offices, and healthcare facilities.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits for HVAC Contractors\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Beam NDIR Sensor:\u003c\/strong\u003e Specifically designed to reduce sensor drift and maintain accuracy of ±30 ppm even in 24\/7 occupied spaces.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Replacement:\u003c\/strong\u003e Simplifies retrofits by serving as the updated substitute for the discontinued \u003cstrong\u003eVeris CWE\u003c\/strong\u003e series.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible BAS Integration:\u003c\/strong\u003e Field-selectable current\/voltage outputs ensure compatibility with almost any \u003cstrong\u003ebuilding automation system\u003c\/strong\u003e input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Resolution Monitoring:\u003c\/strong\u003e Offers 1 ppm resolution and ±2% RH accuracy for comprehensive indoor climate tracking.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCost-Effective Installation:\u003c\/strong\u003e Low operating current and simplified 2-wire or 3-wire wiring configurations reduce material costs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCommon Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the CWE2 suitable for spaces occupied 24 hours a day?\u003c\/strong\u003e\u003cbr\u003e\nYes. Because it utilizes \u003cstrong\u003edual-beam CO2 sensor\u003c\/strong\u003e technology, it does not rely on Automatic Background Calibration (ABC) logic, allowing it to maintain accuracy in hospitals or data centers where CO2 levels never reach outdoor baseline levels.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDoes this unit require frequent recalibration?\u003c\/strong\u003e\u003cbr\u003e\nThe \u003cstrong\u003eself-calibrating CO2 sensor\u003c\/strong\u003e design is built for stability, significantly extending the typical maintenance intervals compared to single-beam sensors.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat wiring is required for the CWE2?\u003c\/strong\u003e\u003cbr\u003e\nIt accommodates 18-24 AWG wiring. For 4-20mA output, it operates on a standard 2-wire loop-powered configuration, while voltage outputs require a 3-wire setup.\u003c\/p\u003e\n\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
