The MERLIN NX Compact VAV (CLMEVA423B24N) with integrated actuator and air flow sensor is a compact, flexible, freely programmable and easy to install Variable Air Volume controller that offers performance-based engineering with Niagara eXtended (NX) and enables Single-Tool-Engineering throughout the whole Building Management System and allowing cost-effective installation and commissioning. Offline engineering (back-office preparation) and ‘live’ engineering for application optimization (real time programming) without download provides an optimized workflow.
