Carrier SPS - Co2;Temperature Sensor

CO2/Temperature sensor
Carrier Sensors 33
Part #33ZCT55CO2
Part #33ZCT56CO2
A CO
2
/space temperature sensor houses two sensors in a single unit. This sensor uses Single Beam
Absorption Infrared™ diffusion technology to monitor carbon dioxide (CO
2
) levels and has a 10K thermistor to
measure space temperature. The controller uses this information to adjust the outside air dampers to provide
proper ventilation and control space temperature.
