Suited for on demand ventilation, Series CDTA combines carbon dioxide, humidity, temperature, occupancy override, and temperature set point measurements in one. Transmitters use Single-Beam, Dual-Wavelength NDIR sensor for carbon dioxide, capacitive polymer sensor for humidity, and band gap sensor for temperature. Field selectable BACnet or Modbus® communications transmit measurements to building controller and allow transmitters to be daisy chained with other communicating sensors.
