Battery-free wireless Green Power controls default to the Zigbee 11 channel. This channel may not be the one used by your Area Manager. To do this, you can change the channel with the following procedure: While holding down the "setup" button on the wireless control, without battery, press the DOWN button on the wireless control, without battery for 5 seconds. Repeat the procedure until the lighting circuit is controlled. See the control data sheet for more details on button placements. You can also find information on the WEOZ technical guide.
