Description
The Lennox 87N54 Ventostat is a high-performance combination sensor engineered to simultaneously monitor three critical indoor air quality parameters: carbon dioxide (CO2) concentration, relative humidity (RH), and ambient temperature. Designed for seamless integration with compatible Lennox HVAC and building automation systems, this sensor delivers the real-time data needed to optimize ventilation, maintain occupant comfort, and support energy-efficient operation.
Key Features
- 3-in-1 sensing: CO2, relative humidity, and temperature in a single device
- Designed for compatibility with Lennox Ventostat ventilation control systems
- Supports demand-controlled ventilation (DCV) strategies to reduce energy waste
- Helps maintain healthy indoor air quality (IAQ) by detecting elevated CO2 levels
- Simultaneous RH and temperature monitoring for comprehensive environmental control
- Compact, wall-mount design suitable for commercial and light commercial applications
- OEM Lennox replacement part — ensures proper fit and reliable performance
Indoor Air Quality Benefits
By continuously tracking CO2 levels alongside temperature and humidity, the Lennox 87N54 enables HVAC systems to modulate fresh air intake only when needed — reducing energy consumption without sacrificing air quality. This demand-controlled ventilation approach is a proven method for meeting ASHRAE 62.1 ventilation standards while keeping operating costs in check.
Applications
- Commercial offices and conference rooms
- Classrooms and educational facilities
- Retail spaces and hospitality environments
- Any occupied space requiring active IAQ monitoring and ventilation control
