I bought the Insteon Togglelinc Relay switch and a SuperSocket outlet module (which is essentially an appliance module built into an outlet.) I'm trying to figure out how to "marry" the switch to the outlet. The switch instructions say that, after putting the switch in "Linking Mode", you have to "press and hold the Appliance Modules's SET button for 3 seconds." I don't see a "SET" button on the SuperSocket, only the unit and house code dials. What am I missing?
