GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM OUTSIDE CARBON DIOXIDE TRANSMITTER CD2OS SERIES PRODUCT DESCRIPTION The outside CO2 transmitter device uses a highly accurate and reliable non-dispersive infrared (NDIR) sensor in an vented, weatherproof enclosure to monitor outside CO2, levels. The sensor uses dual wavelength optics and LTA (long term adjustment) signal processing technology to deliver industry leading long-term accuracy and reliability. Standard features include a field selectable output signal of either 4-20 mA, 0-5 Vdc or 0-10 Vdc for the highest versatility, programmable CO2 measurement span, a backlit alpha-numeric LCD and easy menu operation for configuration. Optional features include a resistive temperature sensor output and a control relay with programmable setpoint,hysteresis and time delay. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The CD2OS should be mounted on an outside North facing wall, under the eaves which will provide protection from direct sunlight and wind. The CD2OS can be mounted directly to buildings wall face using the provided mounting holes. There are 0.85” knockouts for conduit connection. The basic CD2OS has a 3 wire configuration with a screw block terminal provided for connection to the Building Automation System.
