Possible fried STC-1000?

Last night, after I finished wiring my temperature controller, I plugged it in, sparks flew from the outlet, and tripped a few circuit breakers in my house. Upon further inspection, I realized just how much of an idiot I can really be: I had all the wires in the back of the STC-1000 flipped (I had my controller in upside-down compared to the guide I was following). :cross: I unplugged everything and rewired it the correct way (or so I think), and now the unit won't turn on, not a surprise. The strange part to me is that the dual-outlet that I have wired to it is completely functional and is getting full power on both sides. Does this make any sense? Obviously I don't have much experience in electronics and wiring. Thanks!

I followed a diagram that gets posted on HBT pretty often:

You may have shorted the hot/cold relays which would give you power to the duplex outlet. An ohm meter should tell you for sure but it sounds like the unit is toast regardless.

Sounds like you well and truly roasted it.

Nice thing is that they're only $19.

Did you have something plugged into the sockets when you fried it? If so, you put 120V through the sensor IC when you plugged it in and fried the control board. If nothing was plugged in, though, I don't understand how it shorted, as everything should have been isolated from ground by the empty plugs.

Do the relay switches click when you plug in the unit now? I bet what has happened is that the control board shorted in a way such that the relay coils are now constantly energized.

Regardless of this academic discussion, your control is good and toasted.

Right, I did have something plugged in when it shorted. Toasted is what I figured. Now if only I could get all my mistakes to cost $20 to fix!
