Tereasa, I use the search feature first always, or I would not be posting this here. I was hoping maybe someone had created a calculator like the lovely ones we have here. I am new and have only worked with the eco8 and really not sure when one should wick up/down and was looking for guideance, so if you know where I could get a more better understanding of my question, without having to do numerous different types of seaches to try and find something, that would be appreciated, thank you. Dawn .
