Hey guys, been using BrewPi for several years now and LOVE IT! I had my stuff tuned with a chest freezer chamber to keep the beer with +/- 0.03 C for a long time and has been great.
So I’ve now got a stainless conical that chills by pumping glycol through coils down the middle of the conical. My heat source is a conical heat wrap. The conical is insulted with a neoprene jacket. I have my glycol temp set with a separate controller to 10C at the moment. I did have it at 12C but it wasn’t able to get the temp to the set point line. So I lowered the glycol temp. I’ve sense then cleared the overshoot estimater so maybe I need to try raising the glycol temp again.
I’ve read on the forum here that the best method for this setup (given I’m using an Arduino) is to use the fridge constant mode with a single probe. I’ve been testing with that and wanted to see how I can get this to stabilize within 0.3 C. Here’s some values I have current set along with what I’m seeing.
Temperature Idle Range Top: 0.1
Temperature Idle Range Bottom: -0.1
My problem appears to be the minimum heat and cool times but could quite well be my configuration. Is it even possible to get it close to my previous setup (+/- 0.03 C)? How close have others gotten it with a similar setup (with an Arduino)?
