With mine at least, this is not the case. The default of 3 begins ramping far earlier than 3 degrees. I agree, but mine still outputs over 20% if my memory serves me, after peaking the SV Agreed, I only turned I off in order to tune P, to no or minimal overshoot. before applying I.

No I understood what you said, you kept talking about set values. You didn't understand that I was not talking about values despite my explicitly and repeatedly saying otherwise. I challenge you again, to explain your claim knowing that I am not talking about specific values. This elusive...

I said "proportional gain is a reduction in output" You said "This statement is completely dependent upon the controller" There is no "misinterpretation" there. I would like to hear you explain how, when no proportional gain means output is 100% like a thermostat, how applying...

You still think I'm talking about values, I am not. I am sorry you are missing this. What proportional control does, does not change, though the values required for a certain outcome might.

Really, so if I said "aggressive resistance" You would think less resistance? Of course you wouldn't. Proportional gain is a reduction in output, if you call for it to be used aggressively you're calling for more reduction, not less, that is the locution of the term. If you want to use the...

Thanks, I have a feeling you do but the heat capacity of your system vs element wattage and transfer rate absorb it.

I threw those out. You see my post about looking at your output? Curious since you said you had little overshoot and good control if you have any output while above set point with your normal settings, and with I off.

The mypins do by shutting all three off. Yea, your attitude is deplorable at best. You cannot be the least bit confident in that and it's just more petty crap. You're claiming "incorrect information" but you just restated several things I already stated, but in more ambiguous ways. You...

Could you do an experiment for me. I assume you are heating mash water or heating a HLT? Starting from at least 20 degrees cooler than your set temp start your unit up. Press the "set" button so it displays output. What is it ~10 degrees from your set temp, 5 degrees, at, and above it? Repeat...

It's supposed to slow when it's that close to full temp. Try turning off all three P I and D and see what happens. That is straight on off, that will give you an idea of why it's supposed to slow as it gets closer. Just leave D off. Mine never goes down either, even with only P on and no I...

Default settings are 3 for p and 240 for I, what you describe sounds fairly correct with p and I on. The point of PID is to get up to the temp quickly, without way overshooting, and then come down stabilized, if it just cut it off completely it thinks it would dip, so it's trying to softly bring...

Well the actual values can change model to model, or be inverse of each other. That's why I pointed out I wasn't asking about specifics but just general PID logic.

So in other words, even though the actual model of controller didn't matter to answer the question it "mattered to him" because he only helps those with aubrins controllers? The attitude makes more sense now. There are plenty of people here being helpful and I am responding in kind with them...

So, guy announces he thinks I'm defiant and doesn't want to help (despite my straightforwardly answering his question). There's really only one type of person/reason to announce to people you're not going to help, and that's because you are a spiteful person and hope others will follow suit...

Yes I have experimented with this and it does help some, but what I'm trying to confirm is whether or not the controller is acting correctly in the first place. To my understanding I and D disabled it should not be trying to heat at all when above the SV, but that it can oscillate around the set...

It's a mypin TA4 but to my understanding that shouldn't really matter except for specific values, the logic should be the same regardless of the actual controller.

I am trying to manual tune my PID controller. I have got it to a point much better than what the AT got it to (AT made everything terrible actually.). I'm following this short guide. Problem I'm having is with I and D off, the temp is rising past set point, but the controller STILL gives it...

I already got a punch, but I would test something like that on 2$ of sheet metal first.

Wow 15$, wonder how well they work.

I'm sure they can, I just prefer to do as much as I can myself. Less chance of miscommunication, and I would rather have to hold myself accountable for a mistake than someone else.
