Richler Lighting 12388WH Z-Wave Paddle-Style Wall Dimmer must be used in conjunction with the in-line Z-Wave Dimmer 12387. This allows wireless dimming of Design Pro LED Modular 2.0 and Disc 2.0 systems and can be linked with other Z-Wave products. The standard paddle-style switch is sold only in White, but for Light Almond, optional trim ring 12389ALM is needed (sold separately). It features convenient On/Off operation, as well as full-range dimming functions - all with a touch of your finger and installs neatly into a single gang junction box. The 12388WH is 3.5IN wide x 5.5IN high and is compatible with all available Z-Wave home automation equipment. The 12388WH comes one per package. The Z-Wave Dimmer Switch adds even more dimming flexibility to your Z-Wave-compatible Richler Lighting system. Installation is easy, since Z-Wave wireless technology means no additional wiring is required from the lighting fixtures to the switch. Plus, the switch is compatible with Design Pro LED Modular 2.0 and Disc 2.0 products as well as all Z-Wave home automation equipment. Z-Wave is a wireless networking system that allows your home electronics to talk to each other and to you, via remote control.
