The Series CDTA Communicating Carbon Dioxide Detectors combine the function of three room sensors into a single, compact housing. Parameters include carbon dioxide, humidity, 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. The humidity sensor is field replaceable without the need for additional calibration. Optional integral and remote displays are available to display temperature, humidity, 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.
• Minimize inventory and save time by combining CO 2 , RH and temperature measurements into one transmitter
• Reduce installation time with field selectable Modbus and BACnet communications
• Reduces the number of devices mounted in the space with integral humidity and temperature sensors
• Requires minimal maintenance with Automatic Baseline Correction (ABC) to account for sensor drift
• Prevent tampering with physical hardware lockout
• Easily installation with optional remote display tool and simple installation with backplate electrical connection
