The device has 7 connections, so PURE speculation (ie I didn't research):
2 110VAC to the load (hot, neutral)
3 110VAC from the feed (hot, neutral,ground)
2 low voltage to the existing switch (as a dry contact)
so the existing switch is now just a trigger to this module. Any toggle of the switch would cause the load to toggle (like a hardwired 2 way switch, so you can forget that up=on)
or, it could be a trigger like the old cheap X-10 push switches... flip up momentarily to turn on, flip up momentarily to turn off, flip up and hold for dim/bright?
Leviton is waiting on 4.5.2 to be ratified by Zensys (Sigma). Once that is done, the pieces are already in place to get us an updated serial interface.
