Why CO2 Detection Matters
Elevated indoor CO2 levels can cause drowsiness, reduced cognitive performance, and discomfort for building occupants. The Lennox 77N39 continuously monitors CO2 concentrations and signals your HVAC system to increase fresh air ventilation when levels rise — keeping occupants comfortable, alert, and safe while avoiding unnecessary energy waste during periods of low occupancy.
Application
- Residential homes and multi-family buildings
- Light commercial offices and classrooms
- Any space requiring demand-controlled ventilation
