To create the three-way switching, do the following:
Press the Button labeled “Associate” on the Minimote. The Blue LED should blink slowly
On the switch/module to be controlled, double tap the set button. the LED will blink quickly to indicate proper Z-wave communication has occurred
Double tap rocker on the Transmitter to finish the association. The Blue LED will stay on for 2 Seconds to indicate Success
Repeat Step 3 for all additional auxiliary switches if multiple.
Press Any button to exit Association Mode.
