Make sure you purchased the correct STC-1000, marked 110VAC. If it is marked 220VAC or 12V, its not the right one.
I have some major concerns every time I chime in on one of these threads. Are we enabling somebody to undertake a potentially dangerous task without any idea if they can handle it?
None of this is anything that would be tough work for your typical electrician. If all the parts are on hand it's maybe 20 minutes of work. Around here you might pay $70 to have one do the final hookup and make sure it's ok. That may be the best advice for a lot of people.
