Description
The Lennox 23V86 Carbon Dioxide Sensor Kit is a purpose-built CO2 sensing solution designed for use with compatible Lennox HVAC systems. By continuously monitoring indoor carbon dioxide levels, this sensor kit enables demand-controlled ventilation (DCV) — automatically adjusting fresh air intake based on actual occupancy rather than fixed schedules. The result is improved indoor air quality, greater occupant comfort, and measurable energy savings by reducing unnecessary ventilation when spaces are unoccupied.
Key Features
- Monitors indoor CO2 concentrations to support demand-controlled ventilation strategies
- Designed for seamless integration with compatible Lennox HVAC equipment and controls
- Helps maintain healthy indoor air quality by triggering ventilation adjustments based on real-time occupancy
- Supports energy efficiency by reducing over-ventilation during low-occupancy periods
- Kit format includes sensor components needed for a complete installation
- Genuine Lennox OEM replacement part — engineered to factory specifications
Applications
- Commercial and light commercial HVAC systems with demand-controlled ventilation
- Offices, classrooms, retail spaces, and other variable-occupancy environments
- Compatible Lennox rooftop units, air handlers, and packaged systems
