The wall and duct-mounted carbon dioxide (CO especially for demand-controlled ventilation zone applications. The sensor is compatible with Trane VAV and VariTrac and reliable sensing performance come from advanced silicon based NonDispersive Infrared (NDIR) technology. When connected to a building automation system and the appropriate ventilation equipment, the Trane CO sensors measure and record carbon dioxide in parts-per-million (ppm) in occupied building spaces. These carbon dioxide measurements are typically used to identify under-ventilated building zones and to override outdoor airflow beyond design ventilation rates if the CO Please visit Trane representative for more information.
