The CO2/space temperature sensors are comprised of two sensors housed in one unit. They are designed to monitor carbon dioxide levels in the air and measure the interior building temperature. The Carrier 33ZCSPTCO2LCD‑01 indoor air quality sensor measures carbon dioxide levels to support effective ventilation control. Its LCD display, infrared sensing technology, and flexible output options make it well suited for commercial HVAC applications where consistent indoor air quality monitoring is required. Features Clear CO₂ Visibility for Faster Decisions An integrated LCD display provides immediate visibility into current CO₂ levels, helping technicians and facility teams quickly verify operation. This reduces guesswork during installation, commissioning, and routine maintenance while supporting informed ventilation adjustments. Reliable Measurement with Minimal Maintenance Infrared sensing technology delivers stable, accurate CO₂ readings over time. Automatic background calibration helps maintain performance without frequent recalibration, supporting dependable indoor air quality monitoring throughout the life of the sensor. Flexible Integration with HVAC Controls Multiple output options allow the sensor to interface easily with Carrier controllers and ventilation dampers. Compatibility with standard junction boxes and a terminal-block mounting plate help streamline installation in both new construction and retrofit applications.
