Ill be using a xmt7100 (modified) for two SRRs and also tweaked for 12v out for led mod any help would be appreciated. Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. Plug in a mains-rated cable connected to a piggyback spade connector, and then plug the original switched mains cable into the piggyback. I am going into speculation mode here I wonder if your Gaggia came with the steam and brew thermostat positions reversed? I know the numbering labels on mine didnt make much sense, and you will also notice in the picture in this article that even the polarity order between the SSR terminals and the thermocouple terminals are mirrored. What is the intra-shot temperature fluctuation that you are seeing on your machine with your PID setup? Did you have any problems or stumbled upon anything unexpected? Did you try with the SSR unit 40 DA or 40AA? Since installing the modification, I get a huge amount of steam and spray coming out of the portafilter when I first operate the pump so much so, that it sprays all over the worktop around the machine! if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple. My next thought was that the controller wasnt reading the correct temperature. I know wiring might be different colours but is everything in the same place? The result was overshoot of up to 18C and an inability to return to the setpoint temp, 105C, unless I shut everything off and restarted. I figured a video about this could be of interest to you, so here's the link:https://youtu.be/ZAtsuS6B6xg. I start to run the steam at about 130 in the heating cycle on my setup. I used lamp cord for this. Id really love to do the install, however I have ZERO experience in electrical installation. Double sided tape will work. But, I still get loads of steam and spray before it settles down. And this is the thermometer out the back. Realized with your last comment you dont have the offset in place, my bad. I have a 2013 Gaggia Classic. However, depending on the seller, some settings may need to be changed. The .ino file includes several libraries. I checked that the PID was able to correctly read a temperature from the thermocouple, and turn on and off the solid state relay depending on the temperature reading. I cant see how this wouldnt be a thermostat problem, unless you somehow wired the steam thermostat into the PID, but you would have gone way beyond this walkthrough to do that. Even with a perfect offset, you would also need to also take into account the temperature offset between the boiler and the portafilter. Does the PID generate enough heat to melt the Lego bricks? And anything is going to be a huge improvement over the thermostat that the PID replaces. My question is where did you place the SSR, is it near the water spout, right side or in the back if you are facing the front of the machine? Thanks so much for the awesome guide! to use Codespaces. It just overrides the PID and heats up the boiler to the factory preset steaming temperature.Links to parts [None are affiliate links]https://bit.ly/3gL9c95 - XMT 7100 PID unithttps://bit.ly/3xgAHhc - PT100 precision temperature sensorhttps://bit.ly/3wnZD6l - Fotek solid state relay 25Amphttps://amzn.to/3xamPFg - cable sleeve (different widths available)https://amzn.to/2RSAge0 - magnetic tape (example link, different widths available)https://www.thingiverse.com/thing:3671244 - 3D printed case file (print this locally)https://bit.ly/3pPphP0 - the unattractive aluminium enclosure if you wish to go that routeYou will also need:1. Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) At the amperages required to control the boiler heating element, you need an SSR that has enough mass and exposed metal to be able to attach it to a heat sink. Showing all 6 results. Maybe Im missing something? Even if that is the case, i dont have a clue as to why i would be in steam mode, since i didnt touch the steam mode button or its wires, i have already reverted my swap of the power switches wires (just from up to down on the same switch so that shouldnt have impacted anything) and ive validated that the rollback was correct with a multimeter. Do I need to make any adjustments to your procedure to make the PID handle the steam only (not caring about the group head)? You should see a strange number when the PID first powers on, then after about 3-5 seconds it should switch to the temperature reading from the thermocouple. The Rex c-100 reads in Celsius only, would I be able to substitute this kit with: add to list. Ive set the Sn value to pt for the PT100. Main Feature. I strongly suggest checking which switch terminal switches the mains. Gaggia Classic'teki stma sistemi basit mekanik termostatla altndan scaklk 85-105 derece arasnda gidip geliyor ve siz demlemenin hangi scaklkta balayp hangi scaklkta bittiini bilemiyorsunuz. Whole Latte Love has a new video about preinfusion on the classic. All of this really means that you should balance whatever temperature you end up reading against what youre tasting, because thats what matters in the end. The PID will show the temperature, and be somewhat confused by its inability to reach its setpoint, however the PID is bypassed in the same way when the GCP is in steam mode. Tap the neutral mains: disconnect the lower wire from the mains connector at the back of the Classic. You wont need the heat sink, the GCs case does that job for you. 102 is even 3 degrees below my brew temperature. The factory settings have been working well for me, aside from a ~5 degree C overshoot when it first reaches the target temperature. Pantechnicon Wood kit installed on . Does this pid control both the group head water and steam wand? Feel free to hang out, learn a bit, meditate, ride a bike, or perhaps it's just time to move on. Hi Kraken. Did you reverse any wires to the steam switch? Once these bolts are removed, the boiler can be moved around without having to disconnect any hoses or wires. Is this typical? https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd. Because the PID runs on mains voltages, an enclosure is required. Hi Eddie. Because there is very little information on how to install a PID on the latest generation of the New Classic (2018 and newer, also called the Gaggia Classic Pro in North America), here are instructions on to do this. Nikola. The LED on the SSR is functioning but no current can be seen. I have not changed any of the P, I or D settings on my controller. However I dont know if my unit is properly calibrated and/or has a proper offset. Its not a sensor, it doesnt send any information, it just switches on an off, at setpoints that you cant adjust. https://photos.app.goo.gl/Xp37S3o3y6bqqrEk8 An important part is that no internal cables/connectors were modified; all the connections were made by creating splitters using the purchased spade connectors. Leave the Classic powered on for at least 15 minutes. Contrary to the Gaggia circuit diagram, Black is live, White is neutral, a minor issue. I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. You could definitely drill out the adapter a bit to get the thermocouple to fit. I cant see why you couldnt. This approach would make your machine a bit weird to someone who wasnt aware of what you did, as the brew function would be completely unusable without adjusting the temperature. Ill try to get a new thermostat from a reputable place, see if that solves the problem, and if it remains then something else in the machine is wrong. https://www.youtube.com/watch?v=AoZuYaDq5yc, Thanks Jeff, thats a great video. The A vs E should not make a difference as I am not using alarm function, and am using it with a 3-wire PT100. Remove the cover assembly and filler funnel by unscrewing the two small screws at the rear of the top. The cup warmer does seem a bit hotter than before (but have only used twice since installing, so Ill have to pay attention). Then use the left/right buttons to select the digits to increase and decrease, and the up/down buttons to change the digits. The only suprise for me has been that installing steam kit did not help me much because brewing kit alone helped to have great steaming power by only watching temperature climb up to 150 degrees. 3 months later, Ive finally set up the PID and honestly, its a gamechanger! Double check that this is the neutral! Brass is soft and easy to drill, and all the adapter needs to do is provide a connection between the thermocouple and the boiler, so there would be no hard in doing this. 1 / 9. Hey Chris, Im wanting to put the pid into an extended 3d printed driptray. You're welcome to wire your PID however you like but make sure to change any pin numbers in the code to reflect how you've assembeled the circuit. As for your PID always remaining on, it looks like you wired it to the unswitched mains, instead of the switched power. About 60cm of 1mm2 (17AWG) cable to deliver power from the Gaggia to the PID 3. That being said, the original brew thermostat is supposed to be 107C, so could perhaps reach even higher temperatures? Marca: Gaggia: Capacidad: 72 Onzas: Color: Acero inoxidable cepillado: Dimensiones del producto: TopBox with logo : Less than ten left I know what I will be trying tomorrow , Hi, More to explore . You will be working with potentially lethal mains voltages. Find many great new & used options and get the best deals for Gaggia Classic Modified Espresso Coffee Machine - PID, Auto Shot Timer at the best online prices at eBay! I grabbed some screws from my parts bin, I took whatever I could find that was the same color as my filament, and that would fit the holes and hold reasonably well. We have an earth leakage wiring system in our house, but in many countries, these are not standard. Does this mean that I have made the connection properly? This is VERY important! Remove the top of the machine and locate the boiler thermal switch. Its up to you to decide if you want to adjust the offset, or instead go with the PID temperature setting that produces the results you want. So I say go for it, but as Chris said, if you really dont feel comfortable with it, pass on the PID or try to find someone who can install it for you. The PID I ordered came as a package with a solid state relay and a thermocouple, but that thermocouple had too big a diameter to with the Gaggia. Measured everything with multimeter, then realized that C100 doesnt get main while machine is on based on the lights. Wear a glove when reaching in from below, otherwise bloodletting is likely. Its stimulated a lot of interesting discussion! Is 103 degree Celsius the best target temperature fit the PID? I went with an insulated PT100. Thoughts & musings from a product developer and manager. I will monitor it over the next few days, but if the coffee takes good, and the only thing I notice is the warmer cup tray, Ill be fine with that, better in fact! Due to your kind and quick advice, I could order SSR40DA. But that also seems fiddly. However I now need to connect steaming and brewing circuits in parallel rather than serial because steaming circuit will not be closed unless I turn on steaming switch and supply power to steaming SSR. Curtis LMWDP #551 "Taste every shot before adding milk!" Henry_k #5 : by Henry_k February 10th, 2021, 12:35 pm I see no advantage of controling steam temp by PID - if it is 145C or 140C - not a big deal. I have found this PID kit here on Ali express and I think its the same one you fitted can you please tell me if this one is good to go, they got a 3 piece option and a 4 piece option so dont know which, I think the 4 piece option is because it includes a heat sink that you dont mention, so I assume I wont be needing it, can you please advise. Final note: before going down the PID route, the easiest modification to make, and the best starting point for Gaggia Classic modifications, is lowering the brew pressure. Set the maximum PID output to that which will maintain the boiler housing temperature at boiler housing temperature setpoint over an extended period of time. it appears i can configure the BERM REXC-100 like this as i entered the settings after i enabled alarm 1. auber uses 1 SSR & is simple. Converting CUSIP-6, CUSIP-8 and CUSIP-9 to ISIN in PHP, How to automatically block WordPress bot spam without a plugin, which I ordered as an inexpensive kit with a thermocouple and a solid state relay, PID installation in Gaggia Classic causing shortcircuits ColorMag, https://wiki.wholelattelove.com/File:GAGGIA_CLASSIC_2019_Wiring_Schematic.pdf, https://www.youtube.com/watch?v=UETVv0qgz-w, https://coffeeforums.co.uk/topic/53319-what-temp-offset-are-you-using-with-your-pid/, https://diy.stackexchange.com/questions/195229/in-a-light-switch-how-can-i-tell-if-the-black-wire-is-really-hot-and-the-white, https://www.reddit.com/r/espresso/comments/owpfe7/i_made_a_lego_enclosure_for_rex_c100_pid/, https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_asin_image_o05_s00?ie=UTF8&psc=1, https://www.thingiverse.com/thing:4243840, https://www.thingiverse.com/thing:4938828, https://www.reddit.com/r/gaggiaclassic/comments/l5tfcj/mr_shades_pid_installed_decided_to_mount_inside, https://calbryant.uk/blog/well-integrated-pid-temperature-control-of-a-gaggia-classic-espresso-machine/#better-temperature-regulation, https://www.vertex-qis.co.uk/Manuals/PT100_con.pdf, https://photos.app.goo.gl/8yPwJcEPDi1c5tfY7, https://photos.app.goo.gl/Xp37S3o3y6bqqrEk8, https://www.shadesofcoffee.co.uk/post-2018/gaggia-classic-2019ri9480power-switch-mod, Barista Tools that are Worth their Weight in Gold. Everything else (Auber and Mr Shades) includes an M4 thread on their pt100. Do you think its going to blow my machine if I dont do correctly? Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. I am now waiting for my PID unit and thermocouple with M4 head to arrive this week. I then thought what if? and decided to change the mains wires to the opposite terminals. The microfoam created by the commercial steam wand is tight enough for high quality latte art. I love the Lego enclosure idea. Screen Enclosure; Internal Component Housing; Additional Gaggiuino models can be found in the Gaggiuino Model Collection or on Discord in the #mod-3d-design-ideas channel. This will keep things looking tidy. Before replacing the thermostat, maybe check whether your PID and thermocouple are calibrated, before committing to buying more parts. This design is intended to be as simple as possible in terms of the installation, and requires minimal modification to the Gaggia machine. Run the TC leads out through the back of the machine and into the PID, attaching to the MCP9600. To do this, loosen the nut connecting the steam wand to the steam control assembly. Hi guys! This does mean that you can only fill the water tank by pulling it out. Use Git or checkout with SVN using the web URL. Hi Murat. Thanks in advance.
