Enhanced energy efficiency

MERLIN NX offers the highest possible energy efficiency classification 'A' according to the EN 15232 which enables up to 30% energy cost savings but also maximizing comfort and well-being.

What's more, it reduces energy usage via:

  • Common control strategies across HVAC, lighting and shading
  • Demand-based energy generation for optimized cooling/ heating down to the plant control level
  • Application flexibility to freely program requirements, even customizable by room


Flexible integration options

MERLIN NX features a built-in Modbus interface for a multitude of benefits, including:

Wide integration possibilities

Simple integration of Modbus devices such as sensors, I/O modules for light and blind controls, meters, wall modules and much more. Additional option integrates Modbus to DALI or KNX gateways for the ultimate application flexibility.


Flexible expansion of room control systems thanks to its Modbus I/O extension.


Less wiring

Bus wiring to Modbus sensors and remote I/o reduces wiring efforts and associated costs.

Freely selectable wall modules

Choose from an enhanced wall module selection that meets the exact design and functionality requirements. The wall modules are capable of simultaneously handling HVAC, light and blind controls - reducing the number of units required and saving valuable space. Modules can be easily replaced from a wide selection of units at the end of its lifetime or as needed.
