Description
The Carrier 33ZCT55CO2-02 is a dual-function CO2 and space temperature sensor engineered for commercial HVAC building automation applications. By combining carbon dioxide detection and ambient temperature measurement into a single, wall-mounted device, this sensor streamlines installation and reduces the number of field devices needed to maintain optimal indoor air quality and comfort.
Key Features
- Dual-function sensing: measures both CO2 concentration and space temperature simultaneously
- Designed for seamless integration with Carrier building automation and controls systems
- Wall-mount design for convenient room-level monitoring
- Supports demand-controlled ventilation (DCV) strategies to improve energy efficiency
- Helps maintain healthy indoor air quality by monitoring CO2 levels in occupied spaces
- Reduces installation complexity by combining two sensor functions in one unit
Applications
- Commercial office buildings and open-plan workspaces
- Classrooms and educational facilities
- Conference rooms and meeting spaces
- Retail and hospitality environments
- Any occupied space requiring demand-controlled ventilation
Why Choose the Carrier 33ZCT55CO2-02?
Proper CO2 monitoring is a cornerstone of effective demand-controlled ventilation. The 33ZCT55CO2-02 gives building automation systems the real-time data they need to adjust fresh air delivery based on actual occupancy, cutting energy waste without sacrificing occupant comfort or air quality. Paired with Carrier controls, this sensor helps facilities meet ASHRAE 62.1 ventilation requirements and supports green building initiatives.
