Product Details


The Fibaro Z-Wave In-Wall Dimmer 2 is designed to operate with or without a neutral wire. It may be used as a switch in systems without a neutral wire.

In case of 2-wire connection (no neutral), the Fibaro Z-Wave In-Wall Dimmer 2 may require a minimum load of 50W depending on specifics of the connected load.

When used with a Fibaro Dimmer Bypass 2 it may operate with any compatible (see below) load from 5W. Before committing to buy Fibaro Dimmer Bypass 2 please check if your load can be properly controlled by Fibaro Dimmer 2 without bypass device.

Do not connect this device to a power supply without a load. Only lighting devices may be connected to this device.

As a dimmer it operates with the following loads:

  • 230V operated conventional incandescent (from 50W to 250W)
  • 230V operated halogen (from 50W to 200W)
  • 12 V operated ELV halogen lamps and dimmable LED lamps (with electronic transformers: Trailing and Leading edge type) (from 50W to 200W)
  • 12V operated MLV halogen lamps (with frromagnetic transformers) (from 50W to 225W)
  • Dimmable CFL tube lamps with electronic ballast only (from 50W to 200W)

As a switch it operates with the following loads:

  • Compact fluorescent lamps with electronic balast
  • LED bulbs (power factor >0.7)
  • Fluorescent tube lamps with electronic balast

Please note: For loads other than resistive do not exceed a 1.5A current.

This product integrates with all Australian certified (921.42 MHz) Z-Wave and Z-Wave Plus controllers including:

  • Vera 3/ Lite / Edge
  • Fibaro Home Center 2  / Lite

 Please note: Do not mix the load type (e.g. LED and CFL or different type of transformers) as it will impede the proper operation of the dimmer. Doing so will void the dimmer's warranty.

Configuring Z-Wave Devices:

Z-Wave devices often have several configurable parameters which you can change using your Vera’s user interface. These parameters can include things such as the length of time a Z-Wave siren remains active for or the type of manual switch connected to a Z-Wave light controller.

Every available configurable parameter is listed in your device’s user manual. In most cases your device’s default parameters will be suitable to your needs however sometimes it may be necessary to adjust them to optimally use your device. A guide to configuring Z-Wave devices with Vera UI7 is available in the Manuals section.

This product must be installed by a qualified electrician.
Before engaging an electrician, check that they provide a warranty and electrical compliance certificate.

For warranty claim you have to provide an installation compliance certificate from your electrician.
