Question on Serial Expander Lightning


Active Member
When setting up the lightning in the Elk M1 for UPB you set the type as Serial Expander, and the select between Dimmer, Appliance or ON/OFF.

I can understand the difference between Dimmer and On/OFF, but what is the difference between Appliance and ON/OFF? What else do I get? I have used both of them and have not noticed difference (not that I tested all scenarios possible, but tried a few).
