IIRC one has battery backup. One has some slightly different configuration options. They really just keep two lines to "protect" HVAC dealers.
That link really doesn't help much. I'm looking for a comparison of the two versions to see what the differences are.

Well, you just might have to actually follow the links and *READ* the literature the same way anybody else would have to do.
I see that you need protection...
Just from idiots like yourself...
I see dead people.....
