5.0 out of 5 stars Another Sous Vide controller built July 9, 2011
Verified Purchase
The manual can be found at http [colon slash slash] [...] [slash] JLD612_Manual.pdf

Given that I found the manual I had no trouble connecting the 25A SSR Solid State Relay DC:Input AC:Output for PID Temperature Controller and I even used the Heatsink Heat Sink for 25A Solid State Relay (SSR) which is tapped for metric screws, available at ace. I am using the K thermocouple and I had to use the programming adjustment to square the built in display with my Taylor 9842 Commercial Waterproof Digital Thermometer which I decided to trust more than my other digital thermometer.

I inserted the PID/SSR into the black wire of an outlet strip, so that the switch on the outlet strip and the SSR can both turn off the heating elements. I stripped the white wire without cutting it and wire nutted a pigtail on which I hooked to terminal 2, then I cut the black wire and on the hot side I put on two pigtails, one to terminal 1 of the pid, the other to one side of the SSR's AC side. Then I wire nutted a pigtail on the side of the black wire closest to the outlet strip, and attached that pigtail to the other side of the SSR. I even made pigtail color match the hot/neutral black wire/white wire. I didn't touch the green wire at all, if the wall socket is grounded the outlet strip is grounded.

I used yellow/blue to attach the low voltage SSR control circuit, I read somewhere that those are colors used for things that are polarized DC when there is AC around too.

5.0 out of 5 stars Very pleased - sous vide February 1, 2011
By James
Verified Purchase
I purchased this controller to use for a sous vide water water oven along with 11-1/2" Water Heater. Instructions are lacking. After much headache trying to set up an external relay, I found it much easier to use the internal relay on the controller, even though it's only rated for 3 amps. I am very pleased with its accuracy (using a PT100 thermocouple it reads to 0.1 degree F or C accuracy) and the stability of its auto-tune feature (it's able to hold within 0.5 degrees F for at least 3 hours). If the instructions weren't so vague it would have been perfect [...]. I'd definitely recommend this to anyone wanting to DIY a sous vide controller, but experience with electronics is a must!

4.0 out of 5 stars A note for those using a pt-100 probe January 27, 2013
By mkl
Verified Purchase
Perhaps I'm the only one that did not know this, but the red wire/spade connector on the pt-100 probe does NOT go to the terminal on the controller marked + (terminal #9). Red is not positive in this case!

The red wire on the probe goes to terminal #8 (resistor).

The other two wires go to terminals #9 and #10.

Took me several tries to figure this out. Perhaps this will save someone a little time troubleshooting the EEEEE error message the controller displays when the red wire is not connected to terminal #8.

So far the controller seems to work just fine. I'll try to update this review when I have used the Sous vide cooker I'm building for a few months.

It is a great PID but it would be good if you send the manual and wiring diagram with the product.

4.0 out of 5 stars JDL 612 Controller SSR output Stuck ON January 26, 2013
Verified Purchase
I purchased a JDL612 controller, Thermocouple and SSR to try my hand a Sous Vide cooking. I set up a prototype system, Programmed it to the manual (and lots of links on the internet), connected it to a water bath in my Slow Cooker, set it for 130 degree F (SV) and put it into Learn Mode. It heated up through 160 F (PV) and was still climbing. I took it offline and double checked all my program and electrical connections, everything was correct. I tried it again (With cold water) and the same thing happened. This time I noticed that the OUT light on the front of the controller was OFF but the lamp on the SSR was still ON. I tried several other programming and Set Value changes to the same result. The lamp (OUT) would respond properly but the SSR stayed ON. There was 8.1 VDC coming from the controller at ALL times. Should have been 0 or close to 0 when the OUT light was OFF.

I set the perimeter (outY=0) which should have disabled the SSR output, and it was still staying ON.

I have requested a replacement from Lightobject.com through Amazon but haven't heard anything back from them yet (approx 2 days now). I think the unit is defective but with all the good reviews I'm willing to give them a second chance.

I'll keep you updated.

2/2/2013 I received a replacement controller and the new unit corrected the SSR Stuck on problem. The replacement unit is now capable of controlling the Temperature to the Set Value. I still need to work on the PID perameters a little ( The SV=100 and the PV=99 ) after Auto Tuning.

I upgraded the rating to 4.5* from 1*.

5.0 out of 5 stars MY FIRST PID EXPERIENCE, AND IT WAS EASY December 16, 2012
Verified Purchase
I could not be more pleased with this PID and it's ability to keep my smoker running at a constant temperature. The only negative thing I can comment on is the lack of a manual in the packaging, but if you search the model number, JLD612, one of the top three results is a PDF of the manual which had all the information I needed.

I purchased this PID along with an SSR and thermocouple in the hopes of building a decent automatic temperature controller for my smoker. I had priced out the units being sold, and did not feel like spending hundreds of dollars for an automatic temperature controller. I am very happy I decided to build one because it works great! And this PID is amazing at holding the cooking temperature exactly where I need it.

Along with the PID, SSR and thermocouple, I used a laptop power supply, a fan from a PC, a plastic case, and some sheet metal to fabricate a fan mount.

The basic operation is I mounted the fan on the intake of my smoker, I set some coals burning, then I set the desired temperature into the PID. The PID then turns the fan on or off to blow more or less air into the fire to maintain the temperature. The PID did have to go through a short "learning curve" to understand how fast the temp goes up or down and now it basically just keeps the temps almost exactly on the desired temperature. You have no idea how happy that makes me when I am doing overnight cooks of large pieces of meat and now instead of waking up every hour to check the temperature of the smoker I can sleep comfortably all night knowing the PID is handling the job.
