FIBARO Dimmer 2 is a device designed to control various types of light sources in 2 or 3-wire connection. It can switch or dim connected light source remotely using Z-Wave wireless protocol or through the wall switch connected directly to it.
Remotely controlled light dimming module is designed to work with various types of light sources in 2 or 3-wire connection so it can operate with or without neutral lead. Fibaro Dimmer can switch or dim connected light source either through radio waves or through the wall switch connected directly to it. Dimmer 2 is equipped with a smart algorithm of light source detection which makes configuration easier and ensures high compatibility of the device. It may be used as a switch with non-dimmable light sources in 3-wire connection. Active power and energy consumption allows to monitor and reduce electricity bills. Dimmer 2 is compatible with any Z-Wave or Z-Wave+ Controller. As a dimmer it operates under the following loads: • 230V operated conventional incandescent and halogen light sources • ELV electronic transformers (12V operated halogen lamps and dimmable LED bulbs) • MLV ferromagnetic transformers with 12V operated halogen lamps • dimmable LED bulbs • dimmable compact fluorescent CFL tube lamps • supported dimmable light sources with minimal power of 5VA (power factor > 0.5) using FIBARO Bypass FGB-002 Without dimming function it may work with: • compact fluorescent lamps • fluorescent tube lamps with electronic ballast • LED bulbs (power factor > 0.7) • supported light sources with minimal power of 5VA (power factor > 0.5) using FIBARO Bypass FGB-002 https://www.youtube.com/watch?v=K35uFXoa5c0

The Fibaro Dimmer 2 is powered with mains voltage so it is always awake.
1) Disconnect the power supply, remove the Dimmer from the wall switch box, than connect the power supply. 2) Locate the B-button on the housing. 3) Click and hold the B-button to enter the menu mode. 4) Release and click the B-button to choose ""Device reset"" option in the menu that is signaled with the yellow LED indicator colour. 5) After few seconds the device will be restarted, which is signaled with the red LED indicator colour and entering the calibration mode. Note! Resetting the device is not the recommended way of removing the device from the Z-Wave network. Use reset procedure only if the primary controller is missing or inoperable.
