Excel 10™ W7751 VAV II Controller

Excel 10™ W7751 variable air volume (VAV) II controllers provide pressure independent or pressure dependent airflow control and series or induction fan control using single and dual-duct applications. VAV systems generally provide cool air only to the zones. The controllers provide additional outputs that control VAV box reheat coils. The heaters are 3-stage electric or modulating hot water. Supply and exhaust pressurization control are provided on a zone basis.
