Summary
DIN-rail adapter for the Nice DoubleDimmer-Control module (sold separately). Mounts the module neatly in the consumer unit or distribution board, with all wiring on secure screw terminals. Simplified version without front-panel buttons. Colour-coded and labelled for easy identification.
Mount Your Nice Module on a DIN Rail
The Eutonomy euFIX D223NP adapter lets you install the Nice DoubleDimmer-Control module (sold separately) on a standard DIN TH35/TS35 rail inside the consumer unit or distribution board, rather than in a back box behind a wall switch. Keeping the smart switching in one place makes new builds, rewires and commercial installations neater, safer and much easier to service.

Neat, Safe and Professional
The Nice DoubleDimmer-Control module clips into a purpose-made case that sits on the rail like any other DIN device. All of the wiring, including power, the load outputs and the switch inputs, connects to screw terminals on the adapter's base board, so cables are secure, tidy and easy to inspect, and there is no need to work with the module's own small terminals in a tight space.
Simplified NP Version
euFIX D223NP is the simplified version without front-panel buttons. It is ideal where the module will be set up and managed entirely from your Z-Wave controller, and it costs a little less. If you would like to be able to control the module, or add it to and remove it from the network, directly from the board, choose the euFIX D223 version with S1 and S2 buttons.

Colour-Coded and Clearly Labelled
Each euFIX adapter is colour-coded and has space for a label, so every module is easy to identify in a busy distribution board. When you or your electrician come back later to add circuits, swap a module or trace a fault, it is immediately clear which adapter controls which part of the home.
Easy to Maintain
The module sits securely in the adapter but can be taken out again when needed, for example to replace or upgrade it, without disturbing the rest of the wiring. Eutonomy also makes a dedicated removal tool for euFIX Nice adapters, which makes this a quick, tidy job for installers.

Made for the Nice Range
euFIX D223NP is designed specifically for the Nice DoubleDimmer-Control module, part of Nice's Z-Wave range. Once installed, the module works with certified Z-Wave controllers such as Home Assistant, Hubitat and Homey Pro, so you can schedule, automate and control your circuits from anywhere. The Nice DoubleDimmer-Control module is sold separately.
