ECN Forum Forums General Topics of the Trade General Discussion Area Mini Split voltage

I live in New England and aim to install a MRCOOL mini split. The one I want comes in two configurations. 208/230v and 230/208v. Most of the ones I see are 208/230v. Is there a different requirement for wiring the 230/208v? It is a few hundred bucks cheaper due to being able to pick it up in the store. Thanks!
