Calibrating MyPin TD4s

What were the P,I,D, values after autotuning? Did you use icewater?

Really everyones values would be unique to their setup.. You need to have the amount of liquid you would normally brew with running through at the same flowrate it would be flowing at if it were being pulled through a mash and just run the autotune and let it adjust itself. the icewater is only for adjusting the temp probe if its off a few degrees.

Thanks, I missed that connection in my prior searching. I will autotune tonight and check the temp probe after it cools down

What's the difference on the TD4 when the AT lamp is on (solid) vs flashing?

Is the alarm function useful, i.e. alarm at some temp. before boiling?

I dont remember..I believe the state changes when its done autotuning.
Yes the alarm is very useful I set mine to go off at 207 degree before the boilover occurs so I know to put it in manual mode for the boil and can watch it to prevent the boil over.

My old setup I used the alarm a lot because I'd go hangout on the computer while heating. Now I just sit in the garage and drink a beer and have a stogie while that's going so I didn't bother on the next panel I made. For $5 or whatever I think it's worth doing unless you know you won't be leaving your kettle.

Good idea, thanks! I will set a similar alarm
