I'm sorry you got scammed that's a hot water stat some company is trying to sell as incu-stats for more money you can buy at lowes for 8 dollars,but not to worry I use those in my incubators and they work good but you have to make a slight modification,first you need to drill two small holes1/8" in the back then wire one side to the power and the other to the heating element and face the back side toward the element,you will have to adjust it until you reach correct temp,but once that's done they are very accurate and will hold a steady temp,if you have any questions you can pm me good luck!
