MyPin TA4 PID setup

[badgerdan]

I've now wired up my new MyPin TA4 PID for mashing. I've heated up water to with in 10c of the target temp and then ran the auto tune, it didn't seem right so i ran it again but it still isn't there.
Basically i set the target temp to 65c but after it's finished auto tuning it'll turn the element on and off alot, it's every second and that seems to then keep it 1c over. when it's at 65.8 it's still clicking the element on and off.

So, within the menu where can i manually fine-tune so it doesn't switch on the element after 0.5c of the set temp and get it running smoother?
I've not tampered with any other setting within the system, yet.

Where is the probe situated in your setup ? You want it to be measuring the recirculated wort temp immediately after it's passed through your heating vessel (RIMS or HERMS).

I got a Sestos, I had a look in all the menus, I got well lost, anyway I tried the auto tune, it kept overshooting, then intervened.

So as I was planning a brew, the very next morn, I set the timer up, to come on at 5am, with 60lt in a 70lt Thermopot and lid on I went to bed,
At 6-630am I woke to hear the rumble of the element, cool I thought. Back to sleep, just 1/2hr more. Then I woke to water dripping/splashing.
I jumped out of bed to kill the power, but before I killed it the temp said 98C.
So I spent sometime mopping up. Carried on with the brew. Then found out later I had turned the setting from auto to manual.
I've yet to try it in auto. But I'm not setting it and going to bed till I know I can trust it.
This may not be your problem, but it may help someone else.

I have the temp probe in a T-pipe after the ball valve and before the pump just like a Herms.
My TA4 doesn't have manual mode. The autotune is so the system can learn how it heats up and cools down then makes a plan, it switches off when it's finished. Maybe you'd left yours it set to boil and if you'd put autotune on it then would've switched off?

Where is the heater ? Is the probe immediately "downstream" of the heater ?

[badgerdan]

No not really. The element is underneath the base, just like a tea urn.
I'd like it to act a bit more like my STC where is switches off after 0.5 over the temp, but understand this is actually supposed to be cleverer

thats ok while autotuning it will overshoot and can take a lot longer to complete than a standard heat up would too.. the result tho should be a pid set with paramaters tuned to an efficient heat up when then used in pid mode.

for understanding the sestos pid google "auber pid manual pdf" and the 1st link in google should lead you to a document that i think describes the device the sestos pid was based on there are 2 operational differences im aware of 1) the sestos pid wont display in degrees F and 2) iirc the probe assignment codes are different.
