@Elco and fellow BrewPi users Please see attached pictures of my graph, and advance settings. I need so major help trying to make sure my settings look good. Elco Here is what I have based on what you asked. Also please don’t worry about the big drop in the middle, that was me resting all my settings. I am just so lost trying to figure out how to set the settings.
Sorry I forgot to add, I am just testing this in water. in Beer const.
It might be easier to copy the controller/paste the controller JSON.
Given that you have a lot of mass (beer + conical), I think you can increase beer-to-fridge Kp to at least 10. Because you are running in Farhenheit, set it to 18. Due to a bug, this will result in Kp = 10. This will be fixed in next release. The Kp setting is erroneously scaled by 5/9 when running in Fahrenheit.
Set the beer to fridge max lower, to max 10 degrees F. This will prevent windup.
This is just a quick guess. I’ll start celebrating new years eve now and will have more time to help you in 2016.
Cheers 
Awesome thank you @Elco! I will do that. lol Well have fun and be safe. Have a few good cold ones for me. I still have all day until I can join you lol.
@Elco I made the changes as stated but I still think its switching to cooling too much. I m just testing water and the fan is constant running, room temp is 73F. The cooler is sealed good as it is brand new and I checked this as well. The temp in cooler jumps up and down so much. I mean my beer temp is staying right on point but I feel that the cooler cycles a lot. Does this look fine? Please see below.
You can change the period to 40 or 60 minutes instead of 20. Then it will cool less often, but longer.

I’m lost. What setting in the controls is that. Sorry I am still trying to get a good understanding of what each one does. I know that there is a decryption with each one but still a little confused.
The cooler PWM period.
Thanks @Elco. So I made the changes. Could you guys please tell me how this looks: (note: This is in beer const. mode, with 5 gal water in SS brewtech cron. )

That looks okay. I would increase both filters of the beer to fridge PID to get a smoother fridge setting.
Also set the dead time (between heating and cooling) higher than the PWM period.
Okay @Elco, lol sorry but not sure which ones are those in the advance settings . So I am going to change (KP) which is 10 right now, (Ti) which is 7200 right now, (Td) which is 1200 right now. Is this what you are wanting me to set higher? also which one is for the dead time? not sure which one this is. Sorry but still trying to figure this thing out. lol
Dead time is all the way at the bottom.
The two filters are: Beer-to-Fridge Input filter delay time and Beer-to-Fridge Derivative filter delay time.
If you increase the filter delay, you get more averaging, more filtering.
Okay, I was thinking that what’s you was talking about! Thanks again @Elco for getting me setup correctly.
So I made the changes to the setting as stated and I am not sure if it look any different. @Elco can you let me know if this look good or do I need to make more changes? Again this is testing just water.

Well, it is keeping the beer within 0.1 degree while cooling shortly once every 40 minutes. What more do you want?
The peaks up and down in the fridge setting are due to the derivative. If you want them to be lower, you can decrease the beer-to-fridge Kd and/or increase the dead time on the beer to fridge derivative filter.

HAHA I agree 100 %. I just wanting to make sure it looked good. I am going to brew one this week end and watch it go : ). Thanks @elco for your help!
I had a question abou that cooler…mine never turns off…the little fan in side always runs…does get cold tho…does ur do the same
If you connected it the way I did, when you plug the cooler in the fan stays on. It supposed to do that as if it would before the mods to control the compressor. The reason you want to keep the fan on at all time is so that the air is moving constant.
Joe, I really liked how you customized your BrewPi site. I noticed other people had made changes to their site by changing the backgrounds or colors but nobody ever really explained how to do that (web design is not my bag). So thanks for the help in the right direction. Of course as with most things I do, once I get started down a rabbit hole I have to keep going. So here is what mine looks like now:
As you can guess I’m military.
So I took it a step further and changed some of the colors on the chart. To do that, my friend showed me (very quickly) about the web development tools in Firefox. I know other web browsers have a similar function but I only know about Firefox so that’s all I can speak to. With the BrewPi site open, hit F12 to pull up the web development panel. On the very top left of the panel you can select the “element picker”:
Now you can select any item on the page, text, images, backgrounds…
Once you pick an item, the info the browser uses to display that item is listed on the right. What file it’s pulling from and even what line from that file it’s calling out.
Once you know that info you can make the changes as you see fit.
Anybody thinking of making these kinds of changes to their setup I would just add a word of caution and only make one change at a time. Save the file and refresh the web page to make sure everything still works.
