So after 2 hours of trying to understand the terminology of the "manual" I googled for instructions and this wonderful video showed up, i really hope that Ink bird pays you for each person who uses this video for the setup. Thank you very much
By far the absolute best video on PID setup. I use a PID in my temp controlled forge for knife making and this was the video that helped me understand everything in order to set it up properly!
Thank You So Much George! All I needed was one simple explanation (out of this maze - which the manual did not provide) but *You did* awesome sir. I am using ITC-100 as my temperature controller, I've connected a washing machine heating element to the RC as my heating source which I am using to warm up a body of water in a metal container in which a bucket of solidified honey is sitting. The crucial piece I was missing was to set the 'run' function to *Automatic* Bingo!! Your Clarity of explanation is Top Notch! Thanks Again George!🙏
Thank you for doing this. I build an oven for heat treating steel. It will operate around 1550 degrees F. Now all I have to do is figure out this controller and what you have put out here I hope will get rid of my head ache, lol.
Just finished building my PID last night and I did a test run with water in my still. Amazing to watch it work. Looking forward to running my rum wash later this week using the PID controller. Thanks for all of your help George!
Awesome tutorial, but i have a 100VL which has a different menu/settings/ and symbols. Some of the menu system is similar which was a huge help in figuring out at least half of my controller.
Brilliant thank you, this helped me setup my Inkbird IPB 16-S which is effectively the same PID I guess, best instructional Inkbird video on the internet by far.
Built and programmed controller as per your instructions. IT WORKS GREAT. Thanks for your instructions. I also used a glass with a lot of ice and little water, let it sit for 15 minutes, inserted my probe and it read 32.5 degrees F.. I also checked the upper limit with boiling water, as you suggested. Thanks again.
Finished my first PID assembly and settings/parameters setup; it's working great! For the settings, I watched your video, and marked on the instruction sheet what settings you use or underlined what the settings should be. At least that way I have a hard copy of what I want if I mess something up later. You made this easy. Finding the parts, cutting, layout, everything you need is in your videos. It doesn't matter to me how long your videos are, you make it so anyone can understand what needs to be done, and how to do it - at least one way to do it easily. Don't let the nay-sayers get you down. Happy distilling!
I wanted a better controller for my smoker. I looked into a PID controller but was overwhelmed by the complexity. Once I found your channel and heard your explanation of a PID, I ordered an Inkbird controller and set it up. You took the fear out of the whole process. The company should have you write the instruction page. You provide a great service. Thanks for all you do! Jeff
I set my PID controller exactly has you said and it works great. Thank you! Now I did all you that you said, but I do not understand why these values are to be what they are. It would be very enlightening if you explain this a bit more. Your explanation was great, thank you again.
Incredibly well done instructions! Thank you. Could you elaborate on how to use the Autotune setting? You skipped over it to use PID instead of AT. My heat treat oven needs a little finer control than the settings that you suggested.
Thanks for this run through. I'm planning on using an Inkbird PID controller for 120 V controller of an aluminum foundry that I'm building. So far, I'm just hardwired for 1/4 output to dry out the refractory. My next step is to be able to trust that I'm getting a trustworthy reading from my thermocouple!
Awesome series of videos. Thank you. There is a setting that may have an obvious answer but not to me. Hit the set button once an a100 display appears. The number is adjustable from 0-100 and I assume that it is a power adjustment but am not sure. Can you clear up what the function of this setting is. Tia.
Thank you for this video. I used it to get up and running. I have one thing that I'd like to do. I'm using the inkbird to operate a water pump on my heating system. I would like to turn the pump on when the water gets to 130 degrees F and shut off at 150 degrees. I'm operating in on/Off mode. I tried to set the P value but it didn't seem to work.
Hey George, Great video. My question is for controlling an electric smoker. The PID settings of 1-540-200 work but because the heating element stays hot longer when powered down and takes longer to heat when energized, the range is still around 20 degrees. Can you recommend setting to help tweak this range a bit tighter? Which setting should I play with (P, I, D) to experiment with for a closer range. Thanks so much for your information and lessons in layman's terms.
I set up the parameters exactly this way but my boil stops and temp is not held. It probably has about a three degree swing, when Im over sp power turns off as it should bit boiling stops at that point as well. Power kicks back on about 2.5° under sp, boiling starts again and this is the loop.... Heeeelp
I bought a PID controller from you George. I just went through the video again and set all perimeters to what you said. My controller always fluctuates about 7-10 degrees up and down during a run. Not understanding why. My D is set at 200. Any advice would be helpful. I also have to change the df to 0.1 each time. Have a great day
Thank you for this video. I’ve got one of these on an injection moulding machine and for some reason I can’t change the set value. it just has a decimal place the blinks on the right hand side when you press the up and down keys. So I’m hoping some of your guidance on the menus will help me resolve this issue.
Would you possibly be willing to outline the specific settings you use and recommend for beer brewing using a RIMS tube type recirc mash? I’m having issues with overshoot and have tried multiple times to auto tune. TIA.
Hi George, I have watched your clip and I enjoyed your way of presenting the PID set up details. I am just in the beginning, but what I am interested is the "ramp an soak" set up by use of a PID controller. So, could the 106V controller be used for a ramp and soak controlling of a ceramic kiln?
Does the mypin have the option somewhere for manual mode to set the percentage of power that goes to the elements or is that only available on the inkbird.
Hi, Great video. Just got one of these to retrofit on my Rancillio Silvia espresso machine. It's working Ok but trying to tune up the PID values better. The autotune function works but I think I can get it much better as I tune PID controllers at work in a chemical plant. My question is: What are the units for P, I and D on these? For example, is I seconds, 1/sec, etc. The manual doesn't say.
Hello George! Not sure if this problem has been mentioned but I purchased a 240v 5500W element for my 50 Liter boiler. The inkbird with your settings brought the temp of 40L of 40% up within 20 min. As soon as it started to boil (168-172F) it instantly vapor locked the top of my 2" Column (Amount of vapor coming up, blocked condensed liquid from coming down) and alcohol boiled out of head. I attributed this to my tendency to "Over-DO" things such as the purchase of a 5500W Element for 50L Boiler ...LOL I was able to overcome this by swithching 1 thing in the OP "Chapter".... In the third Menu of the OP Chapter (run) If you switch from "Auto" to "mAnu" you can manually set the percentage of AMP output. This means that you can set PID at say 155F and run at 100% (5500W in my case) and then by simply hitting the Set button on the inkbird and switching to AMP display, you can manually set to run at a fraction of the Amperage leading into your first boiling points. As I type this, I am "Equalizing my Column...I found with my set up that running AMPS at 40% is working great. I have the PID set to 172.5F and my Probe is reading 170.2F...I am assuming that this is because the head is full of Methanol vapours and everything else is getting knocked down. I have been running this column/boiler now for over 5 years on Propane...It worked well and I know it inside and out. Your videos and ability to teach gave me the confidence to go outside of my comfort zone and build myself a PID controller...A big reason for the conversion is that I have to buy propane and the Wife pays the hydro bill...HAHAHA Thank you for all you have taught me George! I hope this comment helps others such as myself that went a bit overkill with their Electric conversions.
Thanks for this walkthrough. I installed this PID on my single boiler espresso machine with a desired temperature around 98c. Can I use your proposed settings of P:1, I: 540, d: 200. Because I have heard from other espresso PID users advised that values should be around the following: P: 15-25, I:10-40 and D: 1-3 (near to zero). I am interested in the differences in configuration. A am curious to hear your vision. Currently (Ctl:4, P:18, I:35, D:8) the machine overshoots 16c and undershoots 6c. Thanks for advice
Great video! Thank you for hat you do! I just finished my PID. Is there a way to factory reset the settings and start over again? My PID’s light isn’t blinking when it gets close to temp. Also, I’m using mine for a smoker if that makes any difference. Thank you in advance!
I've got this PID controller wired up to 2-40 watt ceramic heat bulbs for my home made incubator. I used your settings here. The controller is over shooting and undershooting 2 degrees from set temp of 99.5 fereinheight. Is there a way to fine tune this more? Thanks for the video!!
Hi guy's, I'm new to this and have put together inkbird ITC-100 I wish I bought the 106 as George programmed and having issues understanding how to program the 100. If anyone can point me in the right direction I would be very much appreciate the time taken, thanks
As a retired PMEL instructor.. I have seldom seen a guy swerve flap and weave around like this during a how2. Start over and do it better.. going to find another vid...
Well done, George! The Inkbird company should give you a royalty check every time someone watches this video and include the link in their “instructions”. Question: if we use your PID settings, is there still a need to Autotune?
Great video. I am wondering do I need a special contactor. The one I used is just a typical contactor. 240v but when it gets to 3 degrees of set point it cycles on and off which I'm afraid will burn the contactor prematurely. Any help is appreciated
Okay so, setting P.I.D controller you can’t just set it to any old value, the P.I.D controller has to be tuned to the out put device if the output device requires longer times to heat up then those numbers he’s giving you won’t work, the way to tune a P.I.D it to set all parameters to zero.. the P value has the greatest effect on the output and is the parameter that gets you to your set point the quickest, you set you P value till the process value “ temperature “ osculates under and Over the setpoint once you have determined the P value reduce that number by 10%. I value you start to increase till the process value follows the setpoint you may have to fine adjust the P value to get it set just right. D is not needed set to 0 for Temp you only need a P.I controller. The response time for a temperature controller is slow, it takes a while for the heating element to get to temp and for the fluid to reach temperature. D is for fast acting control, if you find that the control is working in reverse you may have to change the control option hot/ cold. One is positive control the others is negative control.
Hey there, I loved the video, it was very helpful. But I have a small issue right now. I am building a small kiln, I have got everything set up, I am using a SSR and Kenthal coils as a heat source. I connected a door switch and It all turned up grate. I programmed my controller exactly like you showed in the video but when I turned it on the display shows some strange things (the “ALM” and “RUN” LEDs turns on and off as long as the “OUT” LED) and the voltage on the coils runs on 220V for a sec and then goes to 0V for like 6 sec, and the temperature is far from the wanted temperature. I have no idea what to do and I will love some help. Thanx a lot
My InkBird 106VH controller seemed to work fine, but when the OUT light turned off, as it should have at the desired temp, the relay stayed open and my heater stayed on, almost killing all my fish in my pond. I found in OP settings it was set to manual inhibit, instead of auto. I HOPE this will solve the problem. If not, what could it be?
So after 2 hours of trying to understand the terminology of the "manual" I googled for instructions and this wonderful video showed up, i really hope that Ink bird pays you for each person who uses this video for the setup.
Thank you very much
This video is amazing! Made it so easy. The whole series made this painless and fun.
Totally agree!
hello from Puerto Rico im so thankful for this kind of masterclass you bring to us waoo so helpful god bless you man

George. Happy distilling. I just wanted to say you vids are still helping. And I hope you are having a happy life.
I just finished my 20 gallon 220 30 amp from a dryer plug. Thank you George without these videos I never would have figured it out👍👍
Glad to help
Incredibly helpful. Thank you for explaining the context of the settings on each "page" of the book! Well done.
Thanks George completed my PID today with alot of your help much appreciated 🙏
Great VIdeo. I wish I someone like you to go through the settings on my VFD now.
Thank you for doing this. I build an oven for heat treating steel. It will operate around 1550 degrees F. Now all I have to do is figure out this controller and what you have put out here I hope will get rid of my head ache, lol.
Still relevant and useful, thanks for all the help George.
You actually managed to help me understand the basics of PID. Well done!

dude, you are an unsung HERO!!!!!!!!!!!!, thanks
Thanks George, I haven't used mine in a while and I can't find the manual. Once again you are a great help
Your video on how to wire, and this video made for a seamless install and set up. Thank you!
Easy, straightforward explanation of what is for me, a sometimes confusing topic. Thanks George...
Wow. This was phenomenal, and so instructive. Thank you!
Thank You. You explain everything clearly so it makes following along easy & stress free! Much Appreciate!!

Watching this before work and I'm excited to get home to finally program the PID & have it working as it can!
Yes, excited to get into the PID lol.
Thanks so much for this excellent walk through. Helped me tremendously!
Huge help sir. Can't wait to get mine up and working.
Wow! You are a perfect teacher! Thanks a lot!
So very helpful as always. Thank you for taking the time to do these fantastic video's Cheers from Scotland :)
Hi George, I just built my first PID controller with the help of your videos, and it's working great. Thanks so much for the great content!
Thank you. I needed that info on the settings.
Beautifully explained. Thanks
What an amazing video! Very easy and informative, thank you so much for your work!
I set my PID controller exactly has you said and it works great. Thank you! Now I did all you that you said, but I do not understand why these values are to be what they are. It would be very enlightening if you explain this a bit more. Your explanation was great, thank you again.
Excellent tutorial! Who says learning can't be fun.
Very Nice channel. Thank you George.
Very helpful George! Thanks!!!
Been using a PID for 12 runs, finally hit the right button and it runs right finally
Can you expand on this? Constantly having issues with mine overshooting by like 20degrees or burning out relays.
I’ve been looking for this video!! Thanks George. Happy Distilling!
Incredibly well done instructions! Thank you. Could you elaborate on how to use the Autotune setting? You skipped over it to use PID instead of AT. My heat treat oven needs a little finer control than the settings that you suggested.
so glad you didn't take this video down
Thank you !!! This was a Huge help and put very well together.
Thanks George I just finished my PID build will be using it soon thanks my friend for great info Cheers!!!
Mr George you are awesome
You’re great to listen too not too funny but casually and you’re slow wich is so important when explaining
Thanks for this run through. I'm planning on using an Inkbird PID controller for 120 V controller of an aluminum foundry that I'm building. So far, I'm just hardwired for 1/4 output to dry out the refractory. My next step is to be able to trust that I'm getting a trustworthy reading from my thermocouple!
You rock i was so lost thank you!!!!!
Can someone explain how the inkbird manual mode works. Thanks
MERCI BEAUCOUP cela ma aider ÉNORMÉMANT très bien présenter
This video saved my ass George thank you!

Great info thanks George. Pity UTube is forcing so many ads into your videos now days. Us guys with slow, expensive internet really take strain.
Thank you for this video. I used it to get up and running. I have one thing that I'd like to do. I'm using the inkbird to operate a water pump on my heating system.

Hey George, everything you are saying is true, I am a dummy and successfully made this work.
I admit I did trip 2 X.
3rd X bing..!

thank you thank you thank you!!
George, this is an awesome video but do you have one on setting up the Inkbird 100 PID?
You’ve been instrumental in getting my first PID set up. Thank you so much. Is this available in a print version?
Thank You !
I bought a PID controller from you George. I just went through the video again and set all perimeters to what you said. My controller always fluctuates about 7-10 degrees up and down during a run.

So I’m hoping some of your guidance on the menus will help me resolve this issue.
Awesome video! I have one question. Is there any need to run the "At" or self tune under the oP menu?
Can i please get a printout of what you wrote in the whiteboard?
Thank you, I felt so stupid reading the directions
Would you possibly be willing to outline the specific settings you use and recommend for beer brewing using a RIMS tube type recirc mash? I’m having issues with overshoot and have tried multiple times to auto tune. TIA.
Hi George, I have watched your clip and I enjoyed your way of presenting the PID set up details. I am just in the beginning, but what I am interested is the "ramp an soak" set up by use of a PID controller. So, could the 106V controller be used for a ramp and soak controlling of a ceramic kiln?
How do you use the factory reset setting
ok, this is epic
The best ever video manual ever in the history of the planet been bade and
Does the mypin have the option somewhere for manual mode to set the percentage of power that goes to the elements or is that only available on the inkbird.
Thank you thank you thank you

Hello George!
Not sure if this problem has been mentioned but I purchased a 240v 5500W element for my 50 Liter boiler.
The inkbird with your settings brought the temp of 40L of 40% up within 20 min. As soon as it started to boil (168-172F) it instantly vapor locked the top of my 2" Column (Amount of vapor coming up, blocked condensed liquid from coming down) and alcohol boiled out of head.
I attributed this to my tendency to "Over-DO" things such as the purchase of a 5500W Element for 50L Boiler ...LOL
I was able to overcome this by swithching 1 thing in the OP "Chapter"....
In the third Menu of the OP Chapter (run) If you switch from "Auto" to "mAnu" you can manually set the percentage of AMP output.
This means that you can set PID at say 155F and run at 100% (5500W in my case) and then by simply hitting the Set button on the inkbird and switching to AMP display, you can manually set to run at a fraction of the Amperage leading into your first boiling points.
As I type this, I am "Equalizing my Column...I found with my set up that running AMPS at 40% is working great. I have the PID set to 172.5F and my Probe is reading 170.2F...I am assuming that this is because the head is full of Methanol vapours and everything else is getting knocked down.
I have been running this column/boiler now for over 5 years on Propane...It worked well and I know it inside and out.
Your videos and ability to teach gave me the confidence to go outside of my comfort zone and build myself a PID controller...A big reason for the conversion is that I have to buy propane and the Wife pays the hydro bill...HAHAHA
Thank you for all you have taught me George! I hope this comment helps others such as myself that went a bit overkill with their Electric conversions.
Thanks for this walkthrough. I installed this PID on my single boiler espresso machine with a desired temperature around 98c. Can I use your proposed settings of P:1, I: 540, d: 200. Because I have heard from other espresso PID users advised that values should be around the following: P: 15-25, I:10-40 and D: 1-3 (near to zero). I am interested in the differences in configuration. A am curious to hear your vision. Currently (Ctl:4, P:18, I:35, D:8) the machine overshoots 16c and undershoots 6c. Thanks for advice
I feel stupid the instructions have me spinning any good info on the 100 version
Great video! Thank you for hat you do! I just finished my PID. Is there a way to factory reset the settings and start over again? My PID’s light isn’t blinking when it gets close to temp. Also, I’m using mine for a smoker if that makes any difference. Thank you in advance!
Hi George,Iam in the process of building one and this explanation is very useful,but I missed how set point is enter.Thanks
I've got this PID controller wired up to 2-40 watt ceramic heat bulbs for my home made incubator. I used your settings here. The controller is over shooting and undershooting 2 degrees from set temp of 99.5 fereinheight. Is there a way to fine tune this more? Thanks for the video!!

As a retired PMEL instructor.. I have seldom seen a guy swerve flap and weave around like this during a how2. Start over and do it better.. going to find another vid...
Great information in the video!
How do I run this PID but use it only when the RUN is manually turned in?
Well done, George! The Inkbird company should give you a royalty check every time someone watches this video and include the link in their “instructions”. Question: if we use your PID settings, is there still a need to Autotune?
Good question.. I'd like to know the answer to that 1
Me to
Great video. I am wondering do I need a special contactor. The one I used is just a typical contactor. 240v but when it gets to 3 degrees of set point it cycles on and off which I'm afraid will burn the contactor prematurely. Any help is appreciated
Could I get more information on lowering the power output using the "output setting-Operation mode" on the Inkbird 106VH?
Thank you
Thanks you fixed my rosin press. 💨🔥💪💚

Great instructional video. I'm having a problem tho. My temperature goes down when it gets hotter. Did I wire or program something wrong?
You have the probe wires backwards. They are polarity specific. If you connect it backwards it reads backwards. Switch the red and black wires.
Likely doesn’t apply to those fine Texas types...but would setting the offset to compensate for altitude adjustment be worthwhile?
Hey there, I loved the video, it was very helpful. But I have a small issue right now.
I am building a small kiln, I have got everything set up, I am using a SSR and Kenthal coils as a heat source. I connected a door switch and It all turned up grate. I programmed my controller exactly like you showed in the video but when I turned it on the display shows some strange things (the “ALM” and “RUN” LEDs turns on and off as long as the “OUT” LED) and the voltage on the coils runs on 220V for a sec and then goes to 0V for like 6 sec, and the temperature is far from the wanted temperature.
I have no idea what to do and I will love some help.
Thanx a lot
My InkBird 106VH controller seemed to work fine, but when the OUT light turned off, as it should have at the desired temp, the relay stayed open and my heater stayed on, almost killing all my fish in my pond.
