This would explain the constant switching on and off. https://photos.app.goo.gl/Xp37S3o3y6bqqrEk8 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. In a nutshell, the Gaggia Classic thermostat is replaced by the combination of the the thermocouple, the PID, and the solid state relay. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. Because the PID runs on mains voltages, an enclosure is required. Popular categories from this store. CONCLUSION! Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. To set the target temperature, press the Set button on the front of the panel. I am glad you solved the problem, Murat. Contrary to the Gaggia circuit diagram, Black is live, White is neutral, a minor issue. The C-100 that I received was set up properly, I only had to change the temperature. Net Weight: about 150g A couple of zip ties come in handy here. However, when I flip the gaggia power switch to off, the PID LCD screen remains illuminated. Its getting very hot indeed so turned it off. Submit a Request Call Us at (888)-389-4123. Shades. The steam mode drops to 102 before the power cycle kicks back in, with the valve open or closed. As the optimal brewing temperature is 90C to 96C depending on taste, this variance means the coffee can be over or under-extracted, or worse - variable. The Gaggia Classic is a very capable espresso machine that gets even better with a couple of improvements. Its one more thing to plug in, but the upside is that it would be electrically isolated from the Gaggia. I opted to follow my connections according to your picture, rather than that text. I did that exercise before installing the PID, behavior should be identical as that time. Replacing that wire= everything works perfectly now! Thx, save. Visit store Contact. Circuit diagram of Gaggia Classic with the KIT-GG connection. Useful Video. You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. Perfect, came back here to ask this question! Im tempted to return the GC because I never used it prior to the mod and it may have been a pre-existing issue. Did you have to alter your thermocouple at all to get it to fit into the adapter, like removing the cap on the end or something? If you go for a PID, you need to use a thermocouple. Your email address will not be published. There are other resources online as well. Main Output: SSR: Open circuit: 4V, Closed Circuit: 24V40mA DC Applications By doing this, the TC bead is pressed against the boiler housing at the point closest to the boiler water, and is assisted by the thermal transfer compound. Or do you think the same set will work with QB-T7100? Its stimulated a lot of interesting discussion! 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 have re-read the specifications for this controller. Here are some pictures of the Lego enclosure: https://www.reddit.com/r/espresso/comments/owpfe7/i_made_a_lego_enclosure_for_rex_c100_pid/. Please be sensible and install a grommet anyway! Hi Kraken. 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. Hi Peter. I am only using the Rex temporarily while working on a project with a Raspberry Pi (and the cost of the Rex was only a couple dollars when ordering the SSR), otherwise I would reprint the entire enclosure with the hooks built in. I had no issues with the K type thermocouple. Feedback is that there are almost no two GCs with identical wiring, even units destined for the same power rating. Then use the cursor keys to select the digits to increase and decrease. Home; Search; Log in; Sign up; Updates: Click here to visit our store! However with the new steaming alarm system, I get a decrease around 10 degrees in steaming temperature as soon as AA SSR shuts down the boiler at the temperature I set, even it turns on right away (my setting is AL:156 AH:155 degrees Celcius). Auber Forum PID Kits for Coffee Machines PID Kits for Gaggia; Poll Moved Topic. https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_asin_image_o05_s00?ie=UTF8&psc=1, BOX I placed the SSR toward the left side of the back panel if facing the front of the machine. It is suitable for other colored espresso machines. My next thought was that the controller wasnt reading the correct temperature. Ive been reading up many different values for the P, I and D, and im not sure where to start. This is probably the most difficult part of the installation. Let me know your thoughts !!! I dont want to void my warranty. Hi Jun. however the one SSR is nice and the modification gives upgraded steam with the solder mod. My theory at the moment would be that due to the PID control the heater is sometimes on at higher temperatures. 2: The add-on item option "extra wire defeating auto-off timer" is for the Gaggia Classic Pro European model (RI9480, 240V), which has the auto-turn-off timer feature. Hi Chris, I am gathering / ordering the parts specified and was surprised to find out the price for 3d printing price spiked. Users needto disable the parameter Tp, Td, and only useTb as a shot timer to pump a specific time. Trim, terminate and connect the wires you routed out the back of the Classic to the PID. Mounting Dimension: DIN: 1/16 (48mmX48mmX80mm) I installed the PID so that there are no permanent modifications to the machine, and the Gaggia can be returned to factory condition at any time. Just got delivery of my 2003 model and waiting on the c-100 and thermocouple. Maybe this could serve instead of trying to find an M4 thermocouple. Do you think this makes a difference? Please contact us if any questions. on orders over $49. Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm. My Gaggia Classic uses 18 awg wire for every connection inside. This works well with a PID for light & medium roasts. If you had to recommend a single display PID, which one would you steer me to? What you do get from the PID as per this guide in steam mode is the ability to see exactly what the temperature of the boiler is, so you can time your steaming to start during a heating cycle, which essentially gives you unlimited steam. Gaggia Babila. Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. But follow chriss advice and be careful and you should be OK. And also use a rubber grommet to route your wires through the slots in the back of the chassis. I am not surprised that the steam kit made little difference. When the pump runs, it vibrates the chassis and it will be a matter of time before it cuts through the wiring insulation. Apologies for the long questions, thanks in advance! Tighten one end of your connector down to one of the solid state relays AC (~) terminals and plug the other end into one of the disconnected thermostat wires. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. The PID unit did not turn on using the same terminal of your machine. Keep the thermostat, in case you want to return the Classic back to factory condition. Hey Chris, Im wanting to put the pid into an extended 3d printed driptray. Do you observe the same temperature ranges? $136.08. European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Take your time, think it through, and be patient. Hi Miguel. Locked Topic . 100% Positive Feedback. Add to cart Buy Now. https://www.youtube.com/watch?v=AoZuYaDq5yc, Thanks Jeff, thats a great video. It also means that you can only see the temperature and access the PID buttons from the top. If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. $375.00. . Hi Jun, and thanks for the update. Which Auber PID for Gaggia Classic? Im on [emailprotected] Tap the switched hot/load mains power: disconnect the lower left-hand (if facing the front of the machine) wire from the power switch. Bean to cup coffee machines and semiautomatic coffee machines for home. Cheers. 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. Even though the wires are insulated, as someone posted earlier, that metal is sharp and the vibration from the machine may eventually cause the insulation to fail and then your whole machine is a conductor. That would be easy enough to verify with a multimeter, to see which thermostat is active in steam mode and which one is active in brew mode. (I am not testifying to the quality of the shots! The little red collar shows the location. Shades. I used lamp cord for this. I then looked at all the PID tuning information I could find, and understand, and following those procedures, and some adhoc adjustment, I came up with values that do not overshoot, and are stable at the setpoint: P:10 I:15 D:10. Some people have done this by replacing the water filler funnel and 3D printing a replacement cover. For me I start steaming when the boiler temperature reads 130 degrees C. So for others who are contemplating going for the extra effort of installing the steam PID, know that the return on investment of doing this is questionable, if not net negative. KIT-GG Installation Guide Version 1.3 Auber Instruments, 730 Culworth Manor, Alpharetta, GA 30022 e-mail: info@auberins.com Tel: 770-569-8420 www.auberins.com . All other variables aside, once you get a temperature that gives you the results you want, you will be able to get those results again, and again. See our 325 reviews on. Thank you for your time. Hello, I acquired and prepared all cables and SSR unit thanks to your well prepared title above. 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. Are the steps here suitable for older machines like mine? Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. () . The pump can be stopped at any time by pressing the ">" key a second time. 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. While the steam switch is engaged, the PID serves to provide a temperature reading of the boiler, which is great, because you can use that temperature reading to time when to start steaming for maximum steam performance. Ive seen the steaming power on the classic remains solid from 125C and up, anything below that results in mediocre steaming power, which makes me wonder if I just have an aftermarket part that shouldnt be on this machine, or is just signs of imminent failure. Connect one meter probe to ground (the GC chassis should always be grounded, otherwise connect to the green wire coming from the power socket at the back). Wire colors and positions seem to vary. Guys, there is mains voltage here. As for your PID always remaining on, it looks like you wired it to the unswitched mains, instead of the switched power. Ive been hearing the solenoid valve click several times while on steam mode as well, and the group head releasing steam on occasions, which also make me worry in terms of the wiring, or the parts just need replacement. Please let us know if theres a way to show our gratitude if theres a charity or cause we can donate to for you putting this guide together. I strongly suggest checking which switch terminal switches the mains. Stay connected. Spent a relaxing boxing day fiddling around with this mod. Contact. Might be easier for most folks to buy an M4 screw, type K, thermocouple direct vs trying to get the probe version then another adapter. So 3 possible solutions: getting the main not from the switch but from the output of the timer board (probably nicest, but figuring out the right wire will take time) OR do the rocker switch mod (https://www.shadesofcoffee.co.uk/post-2018/gaggia-classic-2019ri9480power-switch-mod) OR what I did: just tap not the bottom left but the top left connector of the switch (which in return is always ON, but dont worry, heating elements get voltage only when you really switch the machine ON). (Gaggia Classic) I swear this is the last question I will ask today lol. 1 RELAY alarm: Normal open, capacity 250V/3A AC or 30V/3A DC In your paragraph for connecting the thermocouple, you write thermocouple connects to terminals 6 and 7. Auber Instruments PID Kit for Gaggia Classic. Replies: 2 Views: 1,615. The REX-C100 should work out of the box, set for heating mode, with alarms disabled, and units set to Celsius. Hi Brian. You said here that the to get an M3 thread for the boiler. The on/off temperature can be adjusted by the user. We have an earth leakage wiring system in our house, but in many countries, these are not standard. Watching the steam temp with the PID is interesting (I know it has no effect on it, but it is cool to see how it reacts now) and it is definitely best practice to steam while its on its way up in temp, once it hits the set point it comes down for a while (mine settled around 130 before it started back up). Regarding the M4 screw/ thermocouple, is it possible to amend the picture? I have to mention that coffee taste is good, not harsh or bitter. https://photos.app.goo.gl/8yPwJcEPDi1c5tfY7 When I finished, the whole C100 display just got current only for a sec, then it went out. But that also seems fiddly. My problem is that since installing the mod, my machine gets way too hot and boils. Hi Chris, It is a really tight fit to get the REX C-100 PID inside the machine. It is the perfect place. Obviously the actual water temp will be different, but I can use this range to try and get a consistent temp when I pull a shot. Hi Gene. By the way there are three options as 12V, 24V and 85-250V DC. Cross referencing with the with the manual confirmed that the stickers had been reversed. https://wiki.wholelattelove.com/File:GAGGIA_CLASSIC_2019_Wiring_Schematic.pdf Each segmentcan be set by the user with 0.1 seconds resolution.
