Fibaro Dimmer 2

Current Stock:


The remotely controlled light dimming module, FIBARO Dimmer 2, is designed to work with various types of light sources. It may be connected to two-wire or three-wire configurations, so it can operate with or without a neutral lead. FIBARO Dimmer 2 can switch or dim the connected light source either through radio waves or through the wall switch connected directly to it.
The FIBARO Dimmer 2 is equipped with an algorithm for smart 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).
