This is a temperature control I bought from Amazon manufactured by Control Products. (Link) It is a dual stage high voltage control. Dual stage meaning it will control an outlet for both heating and cooling. High voltage meaning 120 to 240 volts AC.

I had to buy a few things to complete the project. I had to get a male plug, some 12 guage wire, a 20 amp outlet, an outlet box, a wall plate, and a couple conduit fittings.
The first thing I did was to spray paint the box to change it from the galvanized look to black to match the controller box.

I will make more updates to this post as the project progresses.
