Series CDTC Communicating Carbon Dioxide Sensor
The Series CDTC Communicating Carbon Dioxide Sensor combines the function of
two room sensors into a single, compact housing. Parameters include carbon dioxide,
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.
Optional integral display is available to display temperature, 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.
