Part No. CDTC-5N000-LCD
Product Overview
The Dwyer CDTC-5N000-LCD is part of the Series CDTC Communicating Carbon Dioxide Sensors, combining the functions of multiple room sensors in one compact wall-mount housing. It measures CO₂ from 0-5000 ppm and temperature while providing a temperature set point and override function.
The CDTC-5N000-LCD uses a North American wall-mount housing with an integral LCD display. The display can show CO₂ concentration, temperature or temperature set point, providing local access to key room measurements.
Communication is provided through 2-wire RS-485 using either Modbus RTU or BACnet MS/TP, selectable through onboard DIP switches. The RS-485 MAC address can also be configured using the DIP switches. A 4-wire connection and daisy-chain capability can help reduce wiring requirements in multi-device installations.
Barometric pressure can be programmed to compensate for altitude, helping maintain accurate CO₂ measurements at different installation elevations.
The CDTC-5N000 is the corresponding configuration without the integral LCD display.

Frequently Asked Questions
What does the Dwyer CDTC-5N000-LCD measure?
It measures CO₂ from 0-5000 ppm and temperature, and provides a temperature set point with override functionality.
What communication protocols are supported?
The transmitter 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-LCD have a display?
Yes. It includes an integral LCD display that can show CO₂ concentration, temperature or temperature set point.
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 onboard DIP switches.
Can barometric pressure be adjusted?
Yes. Barometric pressure can be programmed to compensate for altitude and support accurate CO₂ measurement.
What is the difference between the CDTC-5N000-LCD and CDTC-5N000?
The CDTC-5N000-LCD includes an integral LCD display. The CDTC-5N000 provides the same core communicating sensor configuration without the integral display.
