Piece of garbage

Would Not Recommend

The digital display is on for a day or 2, then it goes off and I have to reset the thing. I threw the package away or I would have returned it. I ended up throwing it away and buying something different.

Great product,easy to install. Instructions from 4 wire to 2 wire were not quite clear enough. I needed to research a bit more. Love the clean look and the accuracy of temperature control. I replaced 50 year old units with these modern digitals, and i am a mid 70s female....you can do it!
