Carrier® 33ZCT55CO2-02 1109040

The CO2 and space temperature sensors are comprised of two sensors housed in one unit. They are designed to monitor carbon dioxide (CO2) levels in the air and measure the interior building temperature. The sensors use Single Beam Absorption Infrared™ diffusion technology to measure CO2 levels and a 10K thermistor for measuring space temperature. The CO2 levels can then be used as input into a CCN (Carrier® Comfort Network) controller to control the ventilation damper position and ensure an adequate level of outside air in the building as well as space temperature control function.
