The MERLIN NX (CLMERxxN) is a flexible, freely programmable and innovative room 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.
Scalable and flexible integration options over BACnet MS/TP, Modbus and SYLK-Bus enable demand-led control for HVAC, Light and Blind which enables not only high energy cost savings but also maximizing comfort and well-being.

Hardware inputs • a variety of sensors (e.g., room temperature sensors, supply temperature sensors, humidity sensors, window sensors, occupancy sensors, and card readers) may be used
• contact status from occupancy sensors, window switches, condensation contacts etc.
