Right now I'm doing four wf's separate without the res or controller and what alot of work. Don't get me wrong I've used the wf's for awhile and have had great success but it's alot of work and yes in the end it's usually worth it but I am def. interested in switching over to the controller/res recirculating deal. I've been reading and reading and like I said I just can't get my head around how to set it up and I'm usually not very dumb when it comes to this stuff. I sent GH an email and have asked them to post a video or some sort of tutorial. Even their pdf's aren't the greatest but hey they do have them so it's better than nothing. Thanks to all who are helping.
