It provides a comprehensive schematic layout for the connection of cold and hot flow sensors to their respective controllers (CSC 3011) and actuators (MCP 3631-3000). The diagram delineates the signal paths for direct-acting cold dampers and reverse-acting hot dampers, ensuring precise airflow regulation. Designed for HVAC professionals, this manual includes essential information regarding factory and field piping requirements, control wiring configurations, and standardized component locations, facilitating accurate installation and maintenance of pneumatic airflow control systems. By following these standardized specifications, technicians can ensure optimal operational performance and component compatibility within dual-duct ventilation networks.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/technology/","Technology",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/dual-duct-air-terminal-units-control-diagrams/662941/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/dual-duct-air-terminal-units-control-diagrams/662941.png","ImageObject",300,407,{"name":42,"@type":43},"DoDO","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-28",true,{"@type":52,"interactionType":53,"userInteractionCount":33},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What
