Essential Info

The Wireless Relay Receiver Module allows lights and fans to be controlled by AD HOC Battery-free Wireless Light Switches, remotes and sensors (each sold separately). It is an in-line relay that is wired between the light fixture and power source and helps simplify advanced wireless lighting control. Relay receivers learn" the addresses of transmitting switches or sensors. Once programmed (using a simple single-button programming procedure), the receivers respond to ON/OFF commands sent by transmitters stored in memory. This module can be linked with up to 30 wireless transmitters.

    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.
