I have a Carrier aqua snap 30RB110 that takes forever to stage up. It wasn't a big deal a few years ago, but things have started to load up and I want to make it faster. I have heard of a jumper on the board you can cut, but it must be urban legend, because there is nothing in the manual about it. I was targeting 46F LWT yesterday and it took 23 minutes to get it there, and that was with 56F EWT.
