Hey folks, anyone able to offer any advice on why the beer temp is swinging - is this to do with minimum heat and cool times? Any chance of tweaking the PID settings which are as follows:
Kp - 5
Ki - 0.25
Kd - 1.5
In the grand scheme of things its not a huge wobble - 19.83 - 18.94 but I’ve seen people with very little movement and hoped I could tweak something. Using a 30w bar heater in a hacked fridge.
Many thanks Elco - that seemed to keep things much tighter to the set point. I have now updated to .4 firmware and it’s all over the place again - I am bamboozled by the terms, derivative etc, so I just need numbers/settings etc to change. Many thanks.
