This device is a dimmer plug-in and is used between a english (UK) standard wall outlet and lamps connected to a wall outlet by cable. The unit is rated IP 20 and can therefore be used in dry environments only. The unit is included into a Z-Wave network by a remote control, PC software or any other kind of Z-Wave controller. Local operation is possible by pressing the button on the device. The device is a conventional leading-edge phase control dimmer and is therefore only suited for resistive loads such as incandescent lamps of high voltage halogen lamps.
