Description
The Bard HVAC 8403-096BX is a CO2 Sensor with integrated relay designed for use in commercial and light-commercial HVAC applications. This sensor continuously monitors indoor carbon dioxide levels and uses its built-in relay output to signal ventilation equipment — enabling demand-controlled ventilation (DCV) strategies that improve indoor air quality while optimizing energy efficiency.
Key Features
- Integrated relay output for direct control of ventilation equipment or building automation systems
- Monitors indoor CO2 concentration to support demand-controlled ventilation (DCV)
- Designed as an OEM replacement part for compatible Bard HVAC equipment
- Helps maintain healthy indoor air quality in occupied commercial spaces
- Supports energy savings by adjusting fresh air intake based on actual occupancy levels
- Reliable, long-service-life sensing element for consistent CO2 detection
Application
The 8403-096BX is engineered for installation in Bard HVAC systems where indoor air quality monitoring and automated ventilation response are required. By measuring CO2 as a proxy for occupancy, the sensor enables the HVAC system to increase or decrease outdoor air intake only when needed — reducing unnecessary heating and cooling loads while keeping occupants comfortable and safe.
