Wartburg Knight Priority

I recently received a letter that said I had Priority status (I do not have to submit a writing sample, essay, or recommendations) at Wartburg College. I am extremely interested in applying to this college (one of my top choices) but I was wondering if this is their version of applying ED. As I said I love this college but I don’t think that I want to apply ED because of the distance (about 11 hours). If anyone has any insight as to what Knight’s Priority Status could you please tell me before I submit my application because I don’t want to accidently lock myself down with a college right now as I am applying to three others.
