Part No. CDTC-5N000
Product Overview
The Dwyer CDTC-5N000 is part of the Series CDTC Communicating Carbon Dioxide Sensors, combining the functions of multiple room sensors in a single compact housing. It measures CO₂ from 0-5000 ppm and temperature while providing a temperature set point and override function.
The CDTC-5N000 uses a North American wall-mount housing and communicates through RS-485 using either Modbus RTU or BACnet MS/TP. The communication protocol can be selected using onboard DIP switches.
A 4-wire connection and daisy-chain capability can help reduce wiring requirements in multi-device installations. The RS-485 MAC address is configured using onboard DIP switches, while additional DIP-switch settings can control access to the setup menu.
Barometric pressure can be programmed to compensate for altitude, supporting accurate CO₂ measurements at different installation elevations.
The CDTC-5N000 does not include an integral display. The CDTC-5N000-LCD provides the corresponding configuration with an integral LCD display.

Frequently Asked Questions
What does the Dwyer CDTC-5N000 measure?
It measures CO₂ from 0-5000 ppm and temperature, with a temperature set point and override function.
What communication protocols are supported?
The sensor supports Modbus RTU or BACnet MS/TP over RS-485, selectable using onboard DIP switches.
What is the CO₂ accuracy?
The specified CO₂ accuracy is ±40 ppm ±3% of reading.
Does the CDTC-5N000 have a display?
No. The CDTC-5N000 does not include an integral LCD display. The CDTC-5N000-LCD is the corresponding version with an integral LCD.
Can multiple sensors be connected together?
Yes. The sensor supports RS-485 communication with a 4-wire connection and daisy-chain capability.
Can the MAC address be configured?
Yes. The RS-485 MAC address can be set using the onboard DIP switches.
Can barometric pressure be adjusted?
Yes. Barometric pressure can be programmed to compensate for altitude.
What is the difference between the CDTC-5N000 and CDTC-5N000-LCD?
The CDTC-5N000 is supplied without an integral LCD display. The CDTC-5N000-LCD adds an integral LCD while retaining the communicating CO₂ and temperature transmitter functionality.
