The GS-N100-W is a high performance CO2 sensor for today’s demanding DCV applications. It uses Telaire’s NDIR sensing technology and GreenTrol’s high performance signal processing circuitry.
The GS-N100-W time-tested and reliable BACnet MS/TP and Modbus RTU firmware is superior to competitive CO2 sensors. Its reliablilty makes it the only approved network duct mounted CO2 sensor for GreenTrol outdoor air controllers.
When combined with a GreenTrol outdoor air controller, this CO2 sensor can be used to improve traditional CO2 demand control ventilation by using a unique control algorithm that resets the outdoor air setpoint between user defined upper and lower airflow limits (not damper positions) to maintain the space CO2 level. This control method eliminates the under- and over-ventilation that is prevalent with traditional CO2-DCV.
An even more advanced control method uses the measured airflow rate and CO2 level to estimate the population and calculates the required outdoor airflow, thus meeting the actual requirements of ASHRAE Standard 62.1.
Long term stability and high-performance components ensure years of trouble free performance.
