Essential Info

The 3-Way Wireless Light Switch Kit is the perfect solution for adding a 3-way light switch virtually anywhere in your home without needing to run new wire. The kit includes two self-powered wireless light switches and one RF relay (non-dimming) receiver. The receiver is simply wired between the power and the light, and then stored in the light box behind the fixture. The light switches are programmed to the receiver through a simple single-button configuration procedure. This battery-free wireless light switches save you time and hassle by eliminating the need for wires and switch boxes. Traditionally the wireless light switches are surface mounted on a wall with screws or industrial tape but can also be used in a standard switch box or as wireless hand held remotes. The switches are powered by EnOcean technology that converts the press of the switch into a small amount of electricity. This electricity is used to transmit a radio frequency (RF) wireless signal that communicates with the relay receiver. By adding more switches you can create 4-way lighting applications quickly and easily. Or add more relay receivers and control an unlimited numbers of lights. With an RF wireless range of nearly 100 feet, wireless transmitters and receivers allows you to add lighting control from almost anywhere in you home.

    More About These Lighting Controls
    Wireless controls can be placed virtually anywhere and control any device that is within range. This flexibility opens up the opportunity for energy savings that was not available in the past. To accomplish energy savings in an existing home or building, a system of self-powered wireless controls can be installed to decrease the amount of energy used from lights, HVAC units, and devices that draw standby power. Self-powered wireless motion sensors can be used to turn lights and other devices off when a room is unoccupied. Self-powered wireless temperature sensors can be used to set heating or air conditioning to an "economy" setting. A master switch can be used to stop current from entering devices that draw standby power and easily ensure lights, fans, and other devices are off when exiting. Whatever the application, Self-powered Wireless Controls make it easy to implement a cost-saving energy management system.

    CAUTION: The 120V Relay Receiver is to be installed and/or used in compliance with relevant electrical codes and regulations. If you are unsure about any portion of these instructions, please contact a qualified electrician.

    Product is great. Smarthome customer service awful. They did not respond to my installation query. I contacted Ad Hoc electronics and they responded in 15 minutes to answer my question. I will deal directly with ad hoc electronics in the future.
