Series CDTC Communicating Carbon Dioxide Sensor

NDIR CO2 Sensor, Measures CO2, Temperature, Temperature Set Point with Override

The Series CDTC Communicating Carbon Dioxide Sensor combines the function of two room sensors into a single, compact housing. Parameters include carbon dioxide, temperature, and temperature set point with override. A 4-wire connection and daisy chaining together reduces installation cost. The RS-485 MAC address is set up using on-board DIP switches. Additional DIP switches are used to select Modbus® RTU or BACnet MS/TP and to limit access to the set up menu. The barometric pressure can be programmed to correct for altitude. Optional integral display is available to display temperature, or temperature set point instead of CO2.
*For environments occupied 24 hours per day it is recommended to periodically expose the CO2 sensor to outside ambient air.
