Dimming - How to connect multiple control points to a Niko flush-mounting dimmer?

The Niko flush-mounting dimmer that can be extended with an additional control point are: 310-0190x, 310-0280x, 310-0290x, and 310-0390x.

When you wish to replace a two-way switching circuit with a combination push button and flush-mounting push-button dimmer, then you mount the dimmer in the flush-mounting box where the conductor goes to the light source. The two-way switches are replaced by push buttons (e.g. 170-0000x).

If you wish to replace an intermediate switching circuit with two push buttons and a push button dimmer, then install the dimmer in the flush-mounting box where the conductor goes to the light source. The intermediate switch and the two 2-way switches are replaced by push buttons (e.g. 170-0000x).

More details, and the wiring diagrams, can be found in the manual of the relevant dimmer and the technical catalogue on www.niko.eu.
