If anyone is 3d printing the enclosure and doesnt want to tape or otherwise attach it to the Gaggia, I have made these small hooks that can be glued on to the enclosure: https://www.thingiverse.com/thing:4938828. 7. Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. I got the white plastic in one of the stock connectors a bit burned, the plastic looks brown in some areas and a bit melted. Specifications : You said here that the to get an M3 thread for the boiler. 0. Loosen the four bolts that hold down the boiler assembly. I am glad this article helped. When the pump runs, it vibrates the chassis and it will be a matter of time before it cuts through the wiring insulation. Run this wire along the rest of the existing cables and out the back of the Classic, through one of the vent slots. The C-100 can accommodate only one sensor/SSR, so you would only set it for brew temperature. I decided that for me, its not worth worrying about. Perhaps Ill use a spare Arduino or FPGA to PWM the boiler while brewing as someone else was saying. I hope it helps some EU folks not spending extra hours on debugging this minor EU-US model difference . Approach 2: Divert from my writeup by installing the thermocouple so that it replaces the steam thermostat, and set the PID temperature to your preferred steam temperature. The C-100 that I received was set up properly, I only had to change the temperature. Its no secret that the chassis of the Classic has extremely sharp edges. PID temperature control kit for Gaggia Classic Pro 2018+, Classic & Home. This resulted in the PID not powering up even though the machine did. Hello, thanks for the nice and valuable text. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. The PID is really converting the mains voltage to 12VDC both for its internal operation and to drive the SSR, so the PIDs draw is quite small. Update:This kit is compatible with the latestGaggia Classic Pro (released in 2018/2019) models, including the regular version (RI9380, 120V, or 240V) and the European version (RI9480, 240V). and its definately better than Auber which is NOT preinfustion by kicking off solenoid. It would also be a bit of a weird machine, but this approach wouldnt require any mods or re-setting of temperatures to use the machine to brew. Thanks! Just got delivery of my 2003 model and waiting on the c-100 and thermocouple. I found that carefully pushing the boiler up gives better access to the thermostat, either from above, or by reaching up from below. Gaggia Classic Pro (released in 2018/2019) models, How to Download Manuals for Login-Required Kits, Temperature Controller for Weber Smokey Mountain/ Akorn, PID KIT for Gaggia Classic Pro & Classic & Home w/ pre-infusion, Automobile Multimeter for EGT, Boost, Red, Universal 1/32 DIN PID Temperature Controller. So far the temp range Ive seen when the heater cycles on/off (after ~30 mins of warming up) is ~90C to ~97C. I used the same controller ( XMT 7100 ) which Mr Shades is selling. 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. Run two 12 volt wires from the + and terminals of the solid state relay and out the back of the Classic, again using the same slot. It will depend on the beans you use, and your palate. I hope thats ok. 2. Hello Chris, (To be certain, the M4 is the correct one). For RI9403, please check KIT-GGX-EU. 6 Reviews (6) $326.00. 100% Positive Feedback. Same with the adapter screw. 6. Have you checked the temperature accuracy of your PID & Thermocouple? Thread the thermocouple wire through to the back of the machine, and out the same slot as was used for the other wires. Please see the compatible model list below (Note 1 on the bottom). Have you written an article regarding installing a Gaggiuino mod? You would probably blow the fuse in this controller/SSR within seconds. Are the steps here suitable for older machines like mine? Have you noticed any problem using REX-C100FK02 and RTD PT100? The coffee water temperature in the boiler of a home espresso machine is originally controlled by a bi-metal thermostat, which causes a big temperature swing. Thanks in advance for any reply! The fun of the PID is not just the great stability, but the ability to fine tune the brew temperature to your taste! This PID controller kit is designed to retrofit into the European Gaggia Classic espresso machines made after 2015 (model# RI9403). When the ">" key is pressed, the controller starts the brewing sequence automatically. shades uses 2 connecting one ssr thru the other for steam. I ran the Autotuning function couple of times and I am always getting the following values for P, I and D parameters: P=620 , I=32, D=8. If you have the regular version (RI9380 120V, or 240V), you DO NOT need this wire. It has worked without issue so far, and maybe thats bound to happen to the plastic as current goes through and it gets old, but would love to hear other opinions. Before replacing the thermostat, maybe check whether your PID and thermocouple are calibrated, before committing to buying more parts. Thermocouple included: M6*1 thread , K type , 2m cable Display: Dual display for Fahrenheit(F) and Celsius(C) Is there an easy way to set a brewing and steam temp? We bring fresh high-quality coffee to the masses. If you also need features such as steam temperature control, pre-infusion, and countdown timer, please checkKIT-GGPpre-infusion kit. My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). 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. 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? 3. You could approach this two ways. Hey Chris, After the kit is installed, the standby brew watertemperaturecan be controlled to within 1 (F or C) accuracy. Pull off the steam knob and disconnect the steam wand. The little red collar shows the location. Then use the cursor keys to select the digits to increase and decrease. 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. 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 solution is PID control via means of an industrial temperature controller; this is a common modification amongst the Gaggia and Rancillio community. However I dont know if my unit is properly calibrated and/or has a proper offset. If in doubt, sit it out, and get some help. Is there a way to tap into +/- 12Volts inside the GCP? The YouTube video from wll about replacing the boiler made the whole thing very easy. At a minimum, I think you would need the following: I dont see piggyback connectors on Mr Shades list, maybe those are part of the set of wires, but its not clear. 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. I have couple of concerns with this setup and would like to kindly ask for your opinion: 1. Otherwise, it all works properly now. Hi Eddie. This morning I pulled my first shot with the PID. Previous topic - Next topic. That is indeed not normal. Is it possible to do this with the GC factory temp sensor? 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. 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. The same complexity applies to pressure control. Auber Forum. Realized with your last comment you dont have the offset in place, my bad. Whole Latte Love has a new video about preinfusion on the classic. The machine and PID were working great, my brother gave me a quick rundown of the PID basics (how it displays the boiler temp, how it pre-infuses, and then times a 30 second shot pull). If you want to defeat this feature, please add this optionto your order. Hey Chris, Im wanting to put the pid into an extended 3d printed driptray. You could simulate pre infusion by briefly running the pump. Instruction Manual: The instruction manual & installation documents areonly available for download for customers who already purchased the kit. Select Your Mounting option. The thermocouple that I ordered fit into the threaded adapter without any modifications. Do you think this makes a difference? Monday - Friday: 10am - 4:30pm. Have you gone through the (three) menus on the pid , using the instructions of your pid. Use the other probe to check the other two wires coming from the power socket. This product was added to our catalog on Friday 12 August, 2011. Depending on the enclosure, you may need to insert the PID into the housing first. Just leave the SSR disconnected, or dont install it at all. I have briefly thought about pre-infusion but the REX C-100 is not capable of this. The sensor has three wires: 1 x red and 2 x white. 5: The PID controller in this kit is NOT SYL-1512A. (Optional) Add-on Item. I have not changed any of the P, I or D settings on my controller. 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. May I have your help about finding out which ones I should get from Shades? PWM dimmer for preinfusion Hi Miguel. Have had the parts sitting around for months and no time to install! I would like to use it for steaming ONLY. I am going into speculation mode here I wonder if your Gaggia came with the steam and brew thermostat positions reversed? Power supply : 90-265V AC/DC This is an extra piece of wire for the European model of Gaggia Classic Pro (RI9480, 230V) with an energy-saving module, which turns off the machine after about 20 min if not used). Do I need to make any adjustments to your procedure to make the PID handle the steam only (not caring about the group head)? 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. The GC comes from the factory with a simple thermostat that turns on at a certain pre-set temperature, and turns off at another pre-set temperature. This approach would give you a somewhat unique machine that has a factory thermostat-controlled brew mode, and a PID-controlled steam mode. Your Gaggia would be in steam mode by default, you would never have to switch on steam mode. I have a 2013 Gaggia Classic. I found this M8 female to M4 male reducer: https://www.ebay.com/itm/284317077676. I like the quality of the shots, and temperature consistency is more important to me than pressure consistency. This guide should generally also apply to the 2013 GC, but you must assume that any of the switch wiring that I describe will be different for your model year. Thanks in advance! The best simple info I found was a table that summarized what INCREASING each of the PID parameters would do: which I used to adjust my settings. 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. under the name replacement PID kit parts with very low prices. Poll Moved Topic. Please contact us if any questions. Silver case Black case TopBox with logo TopBox with gauge hole. So there is more or less no concern about PID heat and the PID enclosure. Thanks, David. Also noticed if you use the steam for the milk it takes a lot of time to go back down (10min) to the set temp(i do run water through the boiler to bring the temp down, but it floats at a higher temp for a bit), does the steam affect the PID calculation or dont I need to worry about it? 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. The steam mode has its own thermostat, which is very similar to the brew thermostat that the PID replaced, except that its temperature range is more or less as you described. P 53.1 Thanks a lot for the answer. Variants Coffee Only + Installation - No Coffee Only + Installation - Yes Coffee, Steam & Pre-infusion + Installation - No Coffee, Steam & Pre-infusion + Installation - Yes Quantity Free Shipping Parts Then the PID will only switch on when the boiler temperature drops below the target temperature. The PID switches the power to the boiler heating element on and off a lot more frequently than the original mechanical thermostat. Thank you for your time. Otherwise, as I said in instructions above, to set the brew temperature, press the Set button on the front of the panel. Spent some time playing with temps and pulling a lot of shots to dial it in and am very happy with the results. 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. Is there a way to calibrate the read out close to the water out temperature. Here are a couple of examples: Hi Chris, But just like the kit I ordered, the threads on the thermocouple M8 according to the specifications are too big for the Gaggia. Unlike the 7200 model, this one does not have SSR inside. The Auber kit looks easy since I dont have time to build my own. Youre probably fine with either one. If the thermocouple wire is too long, coil it up inside the machine, well away from the boiler or any uninsulated connections, using zip ties to hold the coil in place. 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. But I would definitely read the instructions that come with whatever you receive! With this tight temperature control, you do not have to surf the temperature for frothing because the heater will kick on much sooner than the original thermostat. My experience, and that of others including a commenter on this article, is that I would not want to go lower than 103 on the Gaggia Classic. Does this mean that I have made the connection properly? Hi Ray. What you describe looks very much like the steam thermostat cycle. I placed the SSR toward the left side of the back panel if facing the front of the machine. So I would say yes, you should use a heat sink, but the Gaggia body conveniently provides you with that function. Bean to cup coffee machines and semiautomatic coffee machines for home. Unblocking Solenoid Valve-Classic and Baby. The PID unit did not turn on using the same terminal of your machine. Close the PID enclosure, and attach it to the side of the Classic. https://www.auberins.com. I used P:2,4 I:40 D:10 and Souf:0.2 which gives a shot stability around 2 degrees for single, 4 degrees for double shots. However, when I flip the gaggia power switch to off, the PID LCD screen remains illuminated. 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! Hello. Hello, there is another model without SSR built in with name 7100 instead of 7200. I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. This kit doesn't control the steam temperature nor has the pre-infusion function. What is your coffee bean dark or light? Or do you think the same set will work with QB-T7100? Replies: 2 Views: 1,615. Thanks. Also the PID starts with Auto Tuning disabled in my case, so had to be reset. I think one of either is the one which Shades of Coffee is using. ), Basicknowledge of electronics wiring and safety. If you have a 12v pid could you do everything as you have done except the mains wiring and instead wire the pid directly to an old phone wall charger for power? The idea of the chassis becoming live doesnt bear thinking about. 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). Perhaps you are refering to the video by Damian Witonski. I have noticed after PID installation that upper cup holder tray is getting quite hot during 8-10 min warm-up, which was not the case when I was using the original GCP setup. im trying to find out from shades why shades uses 2. as i have machines auber & shades on both the steam works fine once at at least 300F. See here for details. Thanks Alex! There is definitely a falloff from the temperature reported by the thermocouple at the boiler and what you will measure at the group head. Good idea Chris. The Classics over-pressure valve (OPV) is set to 14 bars, which is a pressure better suited to the use of pressurized portafilters. Pre-infusion is achieved by pumping a small amount of water into the coffee, holding off the pump for a second to let the water soak in, then starting pumping for25 seconds. Hi Chris, thanks for the reply. Thats what Auber and Shades use, although they make their own. Hi Jeff. Thanks for your time. Using pliers to pull the connectors can pinch them on even more tightly, making them extremely difficult to remove. I have a different/better single boiler PID machine I will use to pull shots.
