OK - here goes. I am a living testament for the "DEhumidistat". I will tell you that I bought my CYV last May, but didn't move in until November. After getting my June and July electric bill (thermostat set at about 82), I called
************************ and asked him to please install this device. He did and it saved me almost $100 a month. So, I can vouch for what he says and his ability to install it. If you are away during those hot months in the summer, I really can tell you that you'll save a lot of money in electric bills. And, Handie is our man!!!!!
