It looks like something killed the images on the original post! Any chance someone has a copy of this guide saved somewhere that would include the images you could send me? I was really hoping to do this build
+1, just ordered controller

I built this 2-3 months ago per instructions and it worked fairly well in the beginning. Over the last 6 weeks the temperature has slowly but surely crept up.
It is set to the following:
2 degrees celsius
.3 degrees differential
3 min comp delay time
calibrated at the factory 0 degrees
Do I have a bad unit?
Crossed wires?
Need to adjust my calibration?
It is currently sitting at 9.6 degress C.
Thanks for the help!
Built one of these today thanks to the simple instructions in this post. Replaced the extension cords with some actual plugs for a little cleaner look.
I tried it out with my new 1500 watt immersion heater and had a near catasrophe (a pop, some smoke, and melted wire). I'm hoping this thing will stand up to the demands of the chest freezer I just bought. Used 18 gauge wire, and I think that might have been a mistake.

STC-1000 output relays are only good for 10A. You can't run more than 1200W thru one. At 1500W, you are pulling 12.5A @ 120V. Best practice is to derate the output relays and run significantly less than 10A continuous (compressor start up currents up to 10A should be ok.)
18 gauge wire is ok for short runs of up to 10A (http://www.stayonline.com/reference-circuit-ampacity.aspx), but larger wire won't hurt and will add safety margin.
Looking at the spot where the cord melted, you may have had a defective cord (or that spot was the weakest point if you had a short somewhere else.)
True, but it should still be considered rated at the stated 10 amps..... It has 15A 125V relays in it....

I can tell you what I used. It is from RadioShack, size around 2"x6"x8". I have the STC1000 and two outlets installed. I also used a computer style plug and receptacle. Theres plenty of room for all of it.Hi ,could you please tell me the size of your black box?Thank you.
Thank you very much.

Hi all,
I'm just in the process of building a keezer and I've bought an STC 1000 but I'm a bit worried now because when I search how to build a STC setup they are all about dual controller systems, my question is how do I wire the STC just for the cooling end of things?
Thanks
Mark
I built mine as a two socket system. You don't have to use both.Hi and thanks for the reply,
Are you saying to wire a 2 socket system? I've seen people disconnecting the original thermosat and using it that way,.
What do you think?
