Any Auber experts out there? Let me start off by saying that I am not a high tech person, so I'm having a little trouble understanding how to set this thing up. I've built a new RIMS unit to replace my old one. I'm using a Auber 2352 for temp control. I have it all wired up and ran it through the auto tune procedure. Now here's where my problem starts. I set my target temp to 152 but this thing isnt shutting off at that temp. It just keeps heating. I'm sure this is all operator error. Can anyone explain how to set this up in simple terms? Thanks.

does it just keep heating forever, or does it eventually stop and start to let the temp come back down after it overshoots?

During a test run, I set it to 152. It was around 160 when I decided to turn it off and posted this question. So I don't know if it will shut off on its own.

Have you used a second source for temperature. For example, place a secondary thermometer in the water. Make sure that the temperature is actually reading correctly. Mine is WAY off. I have to get a different thermocouple. But I would have never known if it wasn't for my glass thermometer. If you haven't done that. Give it a try. You might be in the same boat as I am.

Hmmmmm....

It might just be a parameter problem. When I heat up my initial water, i tend to overshoot by 3*F or so. This is after some tweaking of the auto-tuned parameters. My auto-tuned would overshoot by a lot more, so I ended up manually tweaking things.

If you can, do the test but don't bail on it unless the temp gets close to boiling. If it's just mis-configured, you can tweak the settings. If it's totally busted, you will need to replace it. But, the only way to know is to let it roll for a while and see what happens.

No need to heat all the way to 152 for a test. 100*F would be fine.

Until I set the offset on mine I was overshooting by 30. It's not even close to accurate until I hit 140ish. Then it's spot on. I've done multiple brews with it and hit numbers perfectly. I believe it's the way my thermocouple is set up. Auto tune also kind of borked my temps too..

I just turned it on again. This time it started to boil, never shut off on its own. Is it normal for the pv reading to keep climbing? It continually climbed up the ladder. It read about 89 when the water started to boil.

pv is "process value". that's the temp being measured by your probe.

dumb question, but is it perhaps set to measure celsius?
