Philip @#24: I have added some pictures of the jumper wire. Hopefully that will help make it clear.

Aside: I built a second version of the cooker for a friend. I plan to do another whole post about it, but one of the improvements was to use the waterproof Pt100 probe from LightObject. It did not exhibit the “bouncy temperature” problem, and did not require a jumper.

It doesn’t matter which of those two terminals on the SSR you connect to the supply vs. the load. Think of the SSR as analogous to a switch; when it’s closed, there’s continuity between those two terminals, and when it’s open, there’s no continuity. (To answer the question you actually asked: they swap which one is “in” and which is “out” 60 times a second — it’s *alternating* current.)

Note that the control side of the SSR is DC, and polarity very much does matter there. It’s clearly marked, though.

I have the same SSR as you, but I’m not able to tell whether pin 1 or 2 is the AC out or AC in. Could you enlighten me?

Thanks!

Philip @#24:
I think I have the same sensor as you (the one with the metal housing and the metal braid on the outside of the cable), and I had a similar problem at first.

The “jumper” solution involved putting an alligator clip on that metal braid on the outside of the cable, with a wire leading to terminal #9 on the JLD612. (One of the blue wires is also connected to the same terminal.)

I’ll try to add a picture in the next few days.

As for *why* it works, I’m not sure. I’m suspecting electrical noise from the heater being inductively coupled, but I haven’t put a scope on it to check.

I should also point out that the jumper solution hasn’t worked for everybody. (See comment #21 upthread, for example.)

Happy hacking, all.

I just finished my sous vide and thought I had (shockingly) managed to get it all working on the first try. Then the water got over about 50C and the temp from the probe started bouncing all over the place 58, 59, 62, 58, 67…..

I am no electrician but qualified enough to get it all together in the first place. Can you explain the “jumper” solution, possibly with a picture?

Thanks

I have the JLD612 and a PT100 from LightObject (with 1 red and 2 blue wires)

I think I love you! I’m experienced in sous vide, but when I lost my last job, I lost my equipment too…just getting rebooted here at home, and I ended up with jld612, not realizing it wasn’t equipped with AC plugs in and out, so your instructions have been helpful. I’m a philosopher, not an electrician, but I’m sure i can find someone to help me here in Portland, OR. thanks again

Thanks for the article! I have found several similar tidbits of information about privatizing mediawiki out there, but yours is very well laid out.

Pablo @#1: “Is kräusening worth the effort?”

After careful study (read: drinking my way through the batch), the answer is a firm “maybe”.

Is it better than priming with dextrose? Yes, absolutely no doubt whatsoever. Huge flavor difference and also seemingly better head retention.

Better than priming with extract? I’m not sure, never having tried that myself. I suspect the difference is much smaller, but I’d need to try a side-by-side to know for sure. (Hmm… single batch, prime half the bottles each way?)

Hopefully I’ll get my life squared away to the point where I can brew again come December-ish.

Thanks for the comment!

(1) Envy.

(2) I’m not a big fan of the überthief in which you’re supposed to be able to float your hydrometer. I found that it was difficult to remove enough beer to get a good reading. Then again, it may have just been me. Give me the bog standard test cylinder every time.

(3) I’ve had good luck priming with malt extract. Is kräusening worth the effort?
