You can not remove the face of a Ra dimmer and put it behind a blank plate. The RA switch will cease to function when you remove the switch cover because you are also removing the FASS. Without the FASS, the switch will be disabled.
I'm not 100% sure, but I think this is incorrect. I think with the switch cover completely removed the FASS switch contacts close again and the switch comes back on.
This is the first thing I thought of and I've tested it with both a standard Lutron dimmer and also a URC RF dimmer which I think both share the same configuration as RA2. I don't have any RA2 dimmers in stock right now, but have a bunch due in tomorrow.
