Any fuse holder rated for for 110v+ from Radio Shack should work. You will just put a 10amp fuse in the holder. Here is one for $3.49 on radioshack.com.

One other question. I am looking into a thermowell for my fermenter as well. Does anyone have the diameter on the sensor probe that ships with the STC-1000? I have 2 choices in the thermowell I am looking at. I can get one with a .25" diameter or a .3" diameter. I'd like to go with the smaller one if the STC-1000's probe is going to fit.

Do you mean the plastic one or the metal one? There are two different probes that could potentially be shipped with the STC-1000...

The plastic one I have here has a rectangular profile with rounded edges, 6mm x 4.5mm (1/4 x 3/16 inches?). I'd cut 6x5 mm to be safe.

The wire itself is 4 x 1.5 mm (maybe cut 4x2mm to be on the safe side?)

I use a Brewers Hardware 16" straight wall thermowell for my STC-1000 with black plastic sensor.

I took a chance before the STC1000 got here and ordered that same thermowell yesterday. The controller arrived last night and I measured the black plastic sensor to be .25". So I should be good to go with this thermowell.

That is really neat, because the probe that comes with it isn't good for much, frankly!

You just insert the probe in the stainless tube and seal it somehow? Do you have to recalibrate the STC-1000?

The stainless tube is open at one end and sealed at the other. You insert the closed end into your fermenter (many will use either a rubber carboy stopper with an extra hole drilled in it, or the second port on one of those orange carboy caps)

That leaves the open end of the tube accessible from outside of the fermenter. You just slide the temp sensor down into the tube. This allows the probe to be surrounded by your fermenting beer, giving you more precise control of your ferm temp. By being inside the beer, your STC1000 turns your heating and cooling devices on/off depending on beer temp, not ambient air temp

FWIW many people have found that it actually creates less accurate temp control. Because there's so much thermal mass, and it takes a long time for the heat to transfer to or from the center of the beer, using a centrally located thermowell to control temps often results in significant overshoot and wider temp swings. Taping the probe to the outside of the fermenter and covering it with some insulation generally provides much more stable temp control when utilizing simple on/off controllers like the STC-1000. The most accurate and stable temp control would be using a thermowell and a PID type controller.

Of course you'd tell me that after I order a thermowell

I guess could try both methods and determine which works best
