Series CDTC Communicating Carbon Dioxide Sensor

Description: The Series CDTC Communicating Carbon Dioxide Sensor is an innovative solution that combines the functionality of two room sensors into a single, compact housing. This sensor measures carbon dioxide levels, temperature, and temperature set point with override capability, offering comprehensive environmental monitoring in indoor spaces. With features such as a 4-wire connection for reduced installation costs, RS-485 communication protocol, and DIP switch configuration for easy setup, the CDTC sensor provides flexibility and convenience in various applications.

Features/Benefits:

  • Application/Installation Flexibility: Offers flexibility through network communication via BACnet or Modbus®, enabling seamless integration into existing systems.
  • Reliable Readings: Utilizes a dual-channel NDIR sensor to provide accurate readings and reduce drift associated with light source aging, ensuring reliable performance over time.
  • Tamper Resistance: Equipped with physical security hardware lockout, enhancing security and preventing tampering.
  • Easy Setup: Simplifies system setup with an optional remote display tool, streamlining installation and configuration processes.

Applications:

  • Demand Control Ventilation: Ideal for demand control ventilation systems in schools, office buildings, hospitals, and other indoor environments, ensuring optimal indoor air quality.
  • LEED® Certification: Contributes to LEED® certification by providing accurate monitoring of indoor environmental parameters, supporting sustainable building practices.
