Description
The Trane BAYSENS251A is a wall-mounted carbon dioxide (CO2) sensor engineered for reliable indoor air quality (IAQ) monitoring in commercial and light commercial HVAC applications. Designed to integrate seamlessly with Trane building automation and control systems, this sensor continuously measures CO2 concentration levels to support demand-controlled ventilation (DCV) strategies — helping facilities reduce energy consumption while maintaining healthy indoor environments.
Key Features
- Wall-mount design for convenient installation in occupied spaces
- Measures carbon dioxide (CO2) concentration for accurate IAQ monitoring
- Supports demand-controlled ventilation (DCV) to optimize fresh air delivery
- Compatible with Trane building automation and HVAC control systems
- Helps facilities meet ASHRAE 62.1 ventilation standards
- Durable construction suitable for commercial environments
Indoor Air Quality & Energy Efficiency
By continuously monitoring CO2 levels, the BAYSENS251A enables HVAC systems to adjust outdoor air intake based on actual occupancy rather than fixed schedules. This demand-controlled ventilation approach can significantly reduce heating and cooling energy costs while ensuring occupants always breathe clean, fresh air — a critical factor in schools, offices, retail spaces, and other high-occupancy buildings.
Seamless Trane System Integration
As a genuine Trane accessory, the BAYSENS251A is designed to work within the Trane controls ecosystem, providing accurate sensor data to building automation systems and rooftop unit controllers. This ensures straightforward commissioning and reliable long-term performance.
