    How long does an auto tune take?

    I tried auto-tuning, but in my setup, it just screwed things up, so I took Adr_0's advice, and manually tuned. Pretty good now, with temp being held within a 0.3C band at the probe. So in the mash-tun, it evens out beautifully.

    an hour or so but i set then walk away.
    its more about getting a base line to then tweak from.

    Thanks Adr_0 I am greatfull that we have an electronics wizard like yourself on this site . I have approx 5mt of copper coil in my 7.5lt pot and am heating it with a 2400W immersion heater . The question is ,I have a difference between the liquid out into the mash tun @ 67.7* it is 1* under the SV and the difference increases as I raise the temp higher at 87.7* it reads 84.6* . Is there a way of decreasing that difference ? I have an rkc CD101 .

    Just recently purchased a new PID from Inkbird thought my old PID was going haywire , set up the new PID and it was doing a similar thing to my old PID turned out it was the temp sensor was playing up .Slaps hand on forehead .

    Hey Hermies, wondering if I have the same issue. The SYL-2352 PID on my boil kettle shows temp sensor dropping in and out, and eventually goes loopy, flashing all sorts of numbers before freezing. Comes back after being powered down a while. Is that anything like you saw?

    Cheers,

    David
