SERIES CDTA COMMUNICATING CARBON DIOXIDE DETECTOR

Measures CO2, Humidity, Temperature, Temperature Set Point, and Override

The Series CDTA Communicating Carbon Dioxide Detectors combine the functionof three room sensors into a single, compact housing. Parameters include carbondioxide, humidity, temperature, and temperature set point with override. A 4-wireconnection and daisy chaining together reduces installation cost. The RS-485 MACaddress is set up using on board DIP switches. Additional DIP switches are used toselect Modbus® RTU or BACnet MS/TP and to limit access to the set up menu.The barometric pressurecan be programmed to correct for altitude. The humidity sensor is field replaceablewithout the need for additional calibration.Optional integral and remote displays are available to display temperature, humidity, ortemperature set point instead of CO2.
*For environments occupied 24 hours per day it is recommended to periodically exposethe CO2 sensor to outside ambient air.

Product Applications

  • Demand control ventilation in schools, office buildings, hospitals, and other indoorenvironments
  • LEED® certification
  • Minimize inventory and save time by combining CO2, RH and temperaturemeasurements 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 andtemperature sensors
  • Requires minimal maintenance with Automatic Baseline Correction (ABC) to accountfor sensor drift
  • Prevent tampering with physical hardware lockout
  • Easily installation with optional remote display tool and simple installation withbackplate electrical connection
