Hello,
So I have built myself an electric RIMS configuration. I'm using a 30amp Kal clone control panel built with the help of hbt user danbass. After going through my first batch, I was hit with some heating problems. It was suggested that I perform an auto tune so that the PID could learn how fast to heat, etc.
At first, I did this for the recirculation into my mash tun. The temperature stays within a few degrees, and works as I would expect it. I end my recirculation, redirect the mash tun to the boil kettle, and proceed to use the RIMS as a sparge water source. I am able to get up to sparge. Well, to boiling, actually - every time.
If I auto tune for sparge as opposed to when I am recirculating, I can keep a great sparge temperature - again within a few degrees, but I would never get there as I find myself having the same problems with recirculating the mash. The temperature will vary from 130-180. Not ideal. It seems as I can only have one or the other, and I'm trying to figure out why. I do know that I can not sparge and recirculate at the same rate of flow, so I'm guessing this may be a contributing factor.
I have played with the "p" and "t" variables without much success. What should I try?
