But nothing prevents you from using the PID and thermocouple as a temperature indicator. For more information, please see our Guys, there is mains voltage here. Thanks. I do not want to risk damaging my machine because of this. the PWM needs a new wire to the where the pump wire was disconnected. Hi, thanks for the articely, it was great help to do the initial steps. Gaggia Classic Pro/2019 complete wires and controller PID kit - 1/32DIN. . Recently purchased and upgraded Gaggia Classic Pro from Whole Latte Love in late November, and built/installed the Gaggiuino mod myself in February. I did not use a grommet. (Video) PID on Gaggia Classic Pro - Game changer to budget espresso brewing at home Here are the installation steps: Unplug the Gaggia Classic. Youre giving up one of the two temperature readouts, so youll probably only see the actual temperature, as opposed to the target temperature, and I guess you can switch between the two with a button press. The two mains wires connect to terminals 1 and 2 (starting counter-clockwise from top-left). PID KIT for Gaggia Classic Pro & Classic & Home, Pre-Infusion - KIT-GGP (Red) PID KIT for Gaggia Classic Pro & Classic & Home, Pre-Infusion - KIT-GGP (Red) $319.00 RRP $362.00 SAVE $43.00 (12%) Location Availability Online: In Stock Sydney: In Stock Newcastle: No stock Hobart: No stock Add to Cart Wishlist Calculate Shipping Calculate Please make sure you've downloaded them prior to uploading the code to your Arduino of choice. Cup rest Gaggia Classic/Pro portafilter from stainless steel. If not, can you think of any potential mistakes I made along the way? ESP32 IO. The thermostat is a replacement, the original one burned around three years ago. The PID actually only attempts to achieve one temperature (brew temp), the second SSR bastardises a secondary output in order to achieve the second temperature (steam temp). This prompted me to look for alternate solutions. Gaggia Classic - Short Circuit. add to list. Im running into problems and I dont know if my REX-C100s starting values are the problem or if its my deviation with the wiring: Regardless of the temperature that i set on my PID, toggling the Gaggia on causes it to climb to 150-160C and then slowly decline to 118-125C, at which time it will heat up again. It appears to be from 1998 and is barely used. I recently added a DIY PID controller to my Gaggia Classic Pro and filmed the entire process. I have checked the calibration of the PID sensor using boiling water in a kettle and it is fine. Also, the PID generates almost no heat, because the work is done by the SSR, and this is heat-sinked to the Gaggia. Is this typical? Although this is optional, it is difficult to access the power switch to tap power for the PID, and it is almost impossible to reach the thermostat without moving the boiler, and the boiler cant be moved unless the steam wand is removed. The same can be done with the REX C100 but you need one with all 8 screw terminals (the second SSR for steam uses the alarm function which needs terminals #6 and #7) and these two are missing on some REXs. I actually ended up getting the one you recommended. Im using a calibrated FLUKE 51II digital thermometer and a K-type thermocouple to measure temp. To do this, loosen the nut connecting the steam wand to the steam control assembly. I can only find vids and instruction for the pro (does anyone have links for the older version?) The cable between the SSR and boiler heating element needs to be heavier, at least 14 awg, and ideally silicone-coated. One thing I would really recommend when anyone installs a PID system into the Gaggia Classic is to install a rubber grommet where the cables exit the machine. shades uses 2 connecting one ssr thru the other for steam. 102 is way too low, you wont get useful steaming at that low a temperature. Hi Kez. Ive noticed that the PIDs output1 LED isnt illuminated after it climbs above my set temperature (103) but the boiler is getting heated up regardless. Opciones de compra y productos Add-on . Is there a way to calibrate the read out close to the water out temperature. I actually installed mine and then saw your thread, which is awesome to see other people using the same PID. I start to run the steam at about 130 in the heating cycle on my setup. However I dont know if my unit is properly calibrated and/or has a proper offset. YOU ALONE ARE RESPONSIBLE FOR YOUR OWN SAFETY, PLEASE KNOW YOUR LIMITS. Regardless of which thermocouple you choose to use, you will also need to factor in an offset no matter what thermocouple you use, and this is really based on your tastes. Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. This way you are not losing any pressure via the solenoid valve, you are just reducing the initial pressure to the puck by venting some of it through the steam wand. The YouTube video from wll about replacing the boiler made the whole thing very easy. The most I can say is these work for me, and are probably not optimum. When the pump runs, it vibrates the chassis and it will be a matter of time before it cuts through the wiring insulation. Between SSR and PID I was planning on using 22 awg wire given its a lower power requirement. I dont own a multimeter. . 39. r/espresso 24 days ago. My theory at the moment would be that due to the PID control the heater is sometimes on at higher temperatures. About 60cm of FLRY 1.5mm2 cable to connect the SSR to the Gaggia4. I am beginning to suspect that Gaggia created as many combinations of wiring configurations and colors as they made machines. Hi Nish. Once warmed up, the recovery time is quick and the swing is fairly minimal. Do the same with the other connector wire. Im all for freedom of expression and creativity, but not when it might electrocute someone. You should be done! If the brand or source is questionable, I would recommend derating the current by a factor of 2 or 3 and going for a model rated for 25-40A just to be safe. Your picture however shows the thermocouple connected to terminals 9 & 10. Then I realized that EU models come not with a bistable rocker switch but a momentary one (so electricity flows only when you actively pushing the button). 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! The only cable arrangement I had to change after installing the PID was switching those cables in the back, the one on the top I had to put in the bottom, and the one on the bottom in the top, otherwise the PID would stay on when the machine was off, and off when the machine was on. Re-attach the boiler with the four bolts, re-attach the steam wand, push on the steam knob, and put the lid assembly back on, without forgetting to re-connect the two ground wires. I used the same controller ( XMT 7100 ) which Mr Shades is selling. You could simulate pre infusion by briefly running the pump. I have found the exact PID unit which Mr Shades is using and purchased it beside the Rex C100 kit you mentioned above: I purchased an AC to AC SSR (SSR 40AA) which will stabilise steaming temperatures in much smaller margins than the original steam thermostat. Let me know your thoughts !!! 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. Mods for post 2018 - Gaggia Classic Pro / Gaggia Classic 2019 espresso machines View products Mods for pre 2018 - "Original" Gaggia Classic espresso machines View products sign up Glad this writeup helped. It can be installed on Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espresso machines. The PID, RTD sensor and SSR (20 Amps) are installed on Gaggia Classic Pro 2018+. Im thinking Id like to start with just a temperature indicator, to assist with the surfing. Also, the diagram of the controller lists SSR to connects to terminals 9 & 10.

I found that moving the boiler up and to the side allowed me to get to the thermostat from the bottom really easily vs. the top. I have a 2005 GC with a Mr Shades PID kit installed. Have you gone through the (three) menus on the pid , using the instructions of your pid. Privacy Policy. A couple of zip ties come in handy here. 2. Theres also a M4 connected thermocouple wire on Amazon that arrived fast although it increased the whole cost compared to Bangood. Publicado el sbado, 1 de abril de 2023 . To set the target temperature, press the Set button on the front of the panel. The PID switches the power to the boiler heating element on and off a lot more frequently than the original mechanical thermostat. Ive tried connecting these in various combinations but the PV readout is 3 or 4. Adding a PID on and replacing the OPV spring will help for sure, but by that point if you buy the PID as a kit from Auber or Shades that's $200 and the OPV spring from Shades is another $15. Maybe this will help? If your connection is down to just a few strands, that will generate heat. Do not undertake this procedure if you are not comfortable or uncertain. For the Gaggia Classic, taking into account the temperature drop between the boiler and the group head (5-8 degrees C), the PID target temperature should be set to about 103 degrees C or 220 degrees F at sea level. Due to your kind and quick advice, I could order SSR40DA. If you had to recommend a single display PID, which one would you steer me to? I might even have the original box. Hope this helps. P, I, d, controlling period, digital filter coefficient, and more (for control theory experts only) In it's current revision, the Arduino board is still powered via USB so there needs to be an opening to plug in the USB cable. Thank you for making it. It will depend on the beans you use, and your palate. I dont bother with offset, once I have a temperature dialed in, it doesnt matter whether its measured at the boiler or offset for the group head. Follow the included circuit diagram. $399.00 + $19.99 . What you describe looks very much like the steam thermostat cycle. To do that I turned the machine upside-down. Chris has done a great job on this write up and its easy to follow. I have to mention that coffee taste is good, not harsh or bitter. I dont want to void my warranty. Do you have any diagram of the wiringi cant understand how to switch on the steam circuit so the second SSR would not try to heat the boiler in parallel. r . (I believe it is currently on 5) Or shall I just keep it as it is, showing DC 100V when I turn the switch on? I had no issues with the K type thermocouple. Wear a glove when reaching in from below, otherwise bloodletting is likely. Hi Chris, Hi Jeff. Would you be able to post starting values for the PID kit please? I would be glad if you have any recommendations. Do I need to make any adjustments to your procedure to make the PID handle the steam only (not caring about the group head)? And this is the thermometer out the back. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. The MCP9600 board is fastened with a screw to the small ledge inside the 3D printed box. Is there an easy way to set a brewing and steam temp? 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 for your time. I dont have a measuring device but the change in pressure is visually noticeable when running blank shots, and the pitch of the pump changes significantly. The C-100 will fit in vertically, with the screen facing up. D 9. Thanks. This gives the machine a whole new level of consistency, and gives you fine control over brew temperature. Before replacing the thermostat, maybe check whether your PID and thermocouple are calibrated, before committing to buying more parts. Once you are able use the PID temperature readout to determine exactly what the steam cycle is, you know when to start steaming for more or less endless steam. Nikola. So the above instructions might not apply to the UK, I have the GC2019 but the live connection was the top right on the power switch when switched on, bottom left caused the PID to flicker and not work as expected, I fixed my issue but now the PID readout is 103 Dec but the water is 80 degrees, didnt think it would be off by this much. For the Gaggia Classic, taking into account the temperature drop between the boiler and the group head (5-8 degrees C), the PID target temperature should be set to about 103 degrees C or 220 degrees F at sea level. I guess I could revert the machine and see what I get. Awesome PID installation guide! Current Status. I just started working as a barista. The label on REX-C100 says that it is produced by RKC, Japan but you never know for sure :-). Basically, instead of running the pump for a few seconds and then shutting it off (which dumps your pressure courtesy of the solenoid valve) you open the steam valve about 1/4 to half way, hit the brew switch and then slowly close the steam valve (about 5 seconds or so). I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. Ive followed these instructions and installed the mod using the REX-C100, SSR, K-type thermocouple and brass adapter linked in Chris excellent writeup (Thank you Chris). Please be sensible and install a grommet anyway! If nothing happens, download Xcode and try again. Hello Chris, Some shops are quoting $80.00 for the PID enclosure + lid. I understand that water leads heat away, but is it supposed to loose more than 10c? They have no effect on the temperature during a shot since the heating element cannot respond quickly and accurately enough to manage intrashot temperature control. Supposed to be faster in detecting temperature changes and more accurate with the measurement. Thus brewing circuit needs to be connected directly to the heating element, not over steaming circuit. I am thinking to upgrade my classic pro more compact version with below controller. I have few questions for you about this setup. What exactly is a mains-rated wire, and where would I find one? Anyway, thank you Chris. The biggest problem was the fact that the brew water control did not work: the SSR was never switched on by the thermocouple output. I hesitate to identify wires by their color, as the wire colors in the Gaggia seem to vary from year to year and from region to region. I decided to go the do-it-yourself route, ordering the parts separately, at a fraction of the cost of the kits. It really pays off to assume nothing, and test everything. Im assuming it should be fine as well to use 18 awg wire to wire the mains connections to the PID, and between the heating element and the SSR? When the steam switch is on, the PID stays on but because the boiler temperature in steam mode is much higher than the brew temperature of the PID, the PID provides no power to the SSR and heating element. Because the PID runs on mains voltages, an enclosure is required. add to list. From what I gather, youre located in the lower mainland (B.C.)? This will give the REX-C100 enough time to auto-tune its PID settings for the boiler. This works well with a PID for light & medium roasts. Somebody else (Andrue) had also pointed this error out. Mounting Dimension: DIN: 1/16 (48mmX48mmX80mm) It is still showing the M4 screw as the Crossed out/wrong one, and can be a bit confusing. I would not try anything without checking first. Hi Chris or anyone who may know the answer! And anything is going to be a huge improvement over the thermostat that the PID replaces. Pull the cover assembly off by pulling upwards, and disconnect the ground cables. I would like to use it for steaming ONLY. The Arduino board is secured using a small amount of hot glue. Use Git or checkout with SVN using the web URL. . Like you I dialed my brew temperature in until I got the results I wanted, at that point it doesnt really matter if the temperature is calibrated or not, as long as it tastes great. If you can share a picture of it, or a link, I can add it to the article. Gaggia Classic Pro - Gaggia North America Commercial Steam Wand The commercial style steam wand comes equipped with a two-hole tip to perfectly craft velvety microfoam for lattes, cappuccinos, and more. The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. Cross referencing with the with the manual confirmed that the stickers had been reversed. add to list. It also means that you can only see the temperature and access the PID buttons from the top. Contrary to the Gaggia circuit diagram, Black is live, White is neutral, a minor issue. Complete with dual 250W cartridge heating elements (up to temp in ~8mins), bead-blasted stainless steel and internally a hammertone blue powder coat. Its threaded on, and should not be very tight. Do you know how to do this? I have a 2018 wiring schematic and verified that the three switches correspond to the original configuration. Their kit is convenient, and is the way to go if someone doesnt feel ready to take on a 100% DIY project. Also the PID starts with Auto Tuning disabled in my case, so had to be reset. and I didnt work straight through, but I would say the PID took me about 2 hours, not counting the down time due to the crossed power wires. One bit of note and a request. 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.
