CO₂/Temperature Sensor
33ZCT56CO2-02

Space Temperature and CO₂ Room Sensor with Override and Setpoint Adjustment

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.

  • Combined CO₂ measurement range of 0 to 2000 ppm and a 10K thermistor temperature sensor
  • Patented ABC Logic™ (Automatic Background Calibration) self calibration provides lifetime calibration
  • Sleek, low profile
  • Mounting plate with terminal blocks for easy installation and wiring
  • Versatile sensor options including 4 to 20 mA or 0 to 10 v output
  • Set point adjustment potentiometer with a nominal resistance of 100K Ohm ±10%
  • Push button override
  • Locking cover (Allen screws)
