A tag already exists with the provided branch name. Using pliers to pull the connectors can pinch them on even more tightly, making them extremely difficult to remove. SSR control ready to connect external Solid State Relay to handle High current. Also really awesome write up. Thanks again for all your support. This is sold on amazon AC CIRCUITS ARE DANGEROUS AND MISTAKES CAN CAUSE INJURY OR DEATH. Wanted to double check here for some observations a about three months after installing the PID. Shades. . 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?

I did that exercise before installing the PID, behavior should be identical as that time. I might even have the original box. My problem is that since installing the mod, my machine gets way too hot and boils. Thanks for the PID info. A cheap multimeter is all you need. You'll need the following parts, as well as basic soldering tools/skills and access to a 3D printer (if you choose to use the included .stl files) Arduino board of your choice. You need a 85-250V DC model, as the power will be coming from the Classic, which is mains-level voltage. Thanks for your time. 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. add to list. I purchased an AC to AC SSR (SSR 40AA) which will stabilise steaming temperatures in much smaller margins than the original steam thermostat. Sure enough, it powered up. The C100 steps down mains voltage to 12v to power the SSR. Do I need to make any adjustments to your procedure to make the PID handle the steam only (not caring about the group head)? If you used piggyback connectors, it should be a quick job to move the right one over to the correct switch terminal. Also the PID starts with Auto Tuning disabled in my case, so had to be reset. Hello again, I found out that connection I made was wrong. Its no secret that the chassis of the Classic has extremely sharp edges. Any ideas? I am flattered, but will have to pass. I started with 103, and bumped it up to 105. Would you be able to post starting values for the PID kit please? 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. CONCLUSION! 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. PWM dimmer for preinfusion This is probably the most difficult part of the installation. Double check that this is the neutral! - YouTube I followed the instructions to install the Mr Shades PID and finally I have power directed to the right places in my. K type thermocouple, 0-500, 2m cable (6 feet). Never used a K type so I cant say for sure. The lid of the enclosure is held by four screws. But it will require some dismantling of the work you have done. great article !!!! 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. YOU ALONE ARE RESPONSIBLE FOR YOUR OWN SAFETY, PLEASE KNOW YOUR LIMITS. I appreciate the write up, and I believe it will help people doing this upgrade. Do you have any idea how to do? I have only been drinking milk drinks and americanos because the shots I was pulling were always overly bitter, sour, or both, regardless of grind and quantity. I havent lowered brew pressure to 9 Bars yet so perhaps changing that would level out my pump pressures? The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. But I would definitely read the instructions that come with whatever you receive! I plan on doing the same thing as you did, bought both PID simply because the QB-T7100 is slimmer the case is readily accessible from mr. shades, compared to the higher cost of 3d printing a case for the REX. I am guessing that its caused by the current draw of the boiler heater. Also some pids come with a built in relay. add to list Tags Gaggia Classic (Pro) PID controller housing add to list Tags Gaggia Classic Pro Water Reservoir Lid add to list Tags Gaggia Classic Arduino & Touchscreen Housing . Hi Dennis. Learn more. 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. What you describe is pretty normal, except that I am a bit surprised that your steam drops temperature down to 102. I have a question on the pid, it is normal for the brew light to blink (off and) while it stabilizes to the target temperature. You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. As for your PID always remaining on, it looks like you wired it to the unswitched mains, instead of the switched power. Follow the included circuit diagram. I would re-crimp any connections that look suspicious. 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. Guys, there is mains voltage here. I used the same controller ( XMT 7100 ) which Mr Shades is selling. Its crazy. You can buy them at Ace hardware for about twenty five cents each. 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). D 9. Does this mean that I have made the connection properly? Pressure control could be super nice to have. I will purchase the PID kit with thermocouple and SSR from aliexpress and buy these rest small items from Mr. However, depending on the seller, some settings may need to be changed. 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. It should be placed as close to the left-hand side of the Classic as possible. Have you written an article regarding installing a Gaggiuino mod? Try powering the PID directly from mains power, with just the thermocouple connected (disconnect the SSR). Hi Jimmy. Mounting Dimension: DIN: 1/16 (48mmX48mmX80mm) Chris has done a great job on this write up and its easy to follow. I have installed the supply cable for PID unit using piggyback spade connectors. The label on REX-C100 says that it is produced by RKC, Japan but you never know for sure :-). You want to connect the PIDs mains power terminal to the side of the Gaggia power switch that cuts out power when the machine is off. I still have one question you may be able to answer. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. The PID unit did not turn on using the same terminal of your machine. It is a really tight fit to get the REX C-100 PID inside the machine. Thank you Chris for the awesome write up. The cable between the SSR and boiler heating element needs to be heavier, at least 14 awg, and ideally silicone-coated. Connect the two leads you removed from the original thermal switch to the switched AC side of the SSR. My problem is, unlike Rancilio Sylvia, heating element of Gaggia Classic Pro seems impossible to connect without cutting cables. Awesome PID installation guide! One end of the wire should be a male disconnect connector, and the other end should be a spade connector. Can the PID be put inside the machine or does size constraints and/or heat negate that option? The best part is I am only in about $40 on my kit compared to around $150 for the pre made kits. Remove the top of the machine and locate the boiler thermal switch. Leave this cable longer than needed for now, it will be trimmed and terminated later. Pull off the steam knob and disconnect the steam wand. Do you think that REX-C100FK02-V*EN (designed for K-type thermocouple) is compatible with RTD (PT100) and is not going to create long-term problems with the machine/setup? You could definitely drill out the adapter a bit to get the thermocouple to fit. $16.95. Ive been having trouble steaming milk lately, and wonder if there might be something wrong with the thermostat in my machine, wiring problems extending to this as well, or the steam valve might finally be needing a replacement. It can be installed on Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espresso machines. When the temperature stabilizes to within 1 degree of the target temperature, the auto-tuning is complete. 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. Hi Brandon. Hi Chris, You said here that the to get an M3 thread for the boiler. Indeed, not an option. Always double-check your specific models wiring terminal layout and numbering scheme. Its actually reading too high.. 98 deg against 92deg measured by both my oven thermometers. The Gaggia Classic has a max power consumption of more than 1400W, which can easily burn up a cheap SSR. There's a circuit diagram included in the repo. 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. MY GC does the same thing, the pump tone changes when the boiler is heating. i ordered K type and PT100 both for M4. I agree, the PID is a gamechanger. Is it possible, despite setting the temperature to 102 degrees Celsius as SV, to actually run GCP much hotter due to incompatibility of the PID and RTD? Hello Chris, add to list. Without offset the range is between 109-159, still too low. 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. 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. Replacing that wire= everything works perfectly now! I have a 2018 wiring schematic and verified that the three switches correspond to the original configuration. 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 C-100 that I received was set up properly, I only had to change the temperature. The most I can say is these work for me, and are probably not optimum. 40 A SSR; Display; Components. You would need to put the boiler heater element between the controller terminals 2 and 3. It also means that you can only see the temperature and access the PID buttons from the top. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Its not elegant, but does the job to give you a pretty good relative temperature to aid your temp surfing. 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. I have read reports of measurements of up to 8 degrees C lower at the portafilter. Im tempted to return the GC because I never used it prior to the mod and it may have been a pre-existing issue. The thermocouple should be snug but not too tight as the threads are not super robust. If you use anything different you'll need to make adjustments to the 3D printed parts. Hello, The PID, RTD sensor and SSR (20 Amps) are installed on Gaggia Classic Pro 2018+. Shades. Hi Jun, glad you found this helpful. That controller is an interesting find. Hi , I followed the instructions but the PID starts up with some number and it doesnt look normal , LCD just keep blinking some numbers the goes of for a few seconds the I get some numbers for half a second, itso quick I cant tell what is displaying, could I have got the power wiring wrong or if the cable are higher AWG would it causes issue?

I have few questions for you about this setup. Unfortunately, I didnt measure any temperatures for the un-modified machine. I am glad this article helped. Hi Jeff. This is the only concern left for me. When the pump runs, it vibrates the chassis and it will be a matter of time before it cuts through the wiring insulation. 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. Have you got any ideas what might be going on? I have a similar model, C100-Fk02-V*AN. I also think that you may have less difficulty reaching the thermostat, the 2019+ models have a lot less room to spare inside. 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 all for freedom of expression and creativity, but not when it might electrocute someone. If its closed it takes longer for temperatures to drop, but still goes to 102 before the it power cycles. I think one of either is the one which Shades of Coffee is using. For the sake of piece of mind, I have ordered last night a K type thermocouple in order to replace the RTD P100 and close the open loop in my head about PID type and sensor. I am going into speculation mode here I wonder if your Gaggia came with the steam and brew thermostat positions reversed? https://wiki.wholelattelove.com/File:GAGGIA_CLASSIC_2019_Wiring_Schematic.pdf There are other resources online as well. If nothing happens, download Xcode and try again. Hi Eddie. I had no problem with my mod other than the stickers on the back of the PID were reversed, so the terminal markings were not correct. I would be surprised if your water is 80 degrees coming out of the boiler with the PID set to 103, but its possible, depending on the thermocouple youre using. Hi, thanks for the articely, it was great help to do the initial steps. 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. You signed in with another tab or window. THIS ASSUMES YOUR COMPETENT WORKING WITH AC CIRCUITS. Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm.

Free shipping. Thanks in advance! Thus brewing circuit needs to be connected directly to the heating element, not over steaming circuit. 1 / 9. 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. Great guide. Do you think this makes a difference? Because the wiring connections can vary between manufacturers, you should bench-test your setup before final assembly. I would not try anything without checking first. Did you try it? Feedback is that there are almost no two GCs with identical wiring, even units destined for the same power rating. How to install a PID on a Gaggia Classic Pro - DIY, cheap and good looking! Test that everything is working before closing the machine back up. Nevertheless, it will take some time to get it and make a change of the temperature sensor. Apologies for the long questions, thanks in advance! Have had the parts sitting around for months and no time to install! As for steam, the guide I wrote leaves the steam function completely untouched. I was originally going to go with the gaggiuino, but this PID and dimmer mod are 100x easier GAGGIA Classic, parts, set, kit - Gasket Repair kit for Classic, Baby, Evolution. I managed to succeed on brewing side with DA SSR however I could not find an appropriate diagramm for adding my AA SSR for steaming alarm function. I decided to go the do-it-yourself route, ordering the parts separately, at a fraction of the cost of the kits. (Video) PID on Gaggia Classic Pro - Game changer to budget espresso brewing at home Here are the installation steps: Unplug the Gaggia Classic. add to list. The boiler in the Gaggia can get hot enough to melt non-silicone insulation so if you don't have silicone wiring, make sure to keep any wiring well clear of the boiler. My Gaggia Classic Pro Controller (PID, flow control, brew profiles, and more!) Basically, you can install two separate PID controllers one for each boiler. If you do this, consider counter-sinking the magnet so that it is flush with the outisde of the box. The SSR is just a fancy switch and it should only be turning on and off, so depending on how you measure you may not see current. 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. It would be great to see how the machine is behaving without the PID, to get a baseline. Thanks. Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. The sensor has three wires: 1 x red and 2 x white. The C-100 will fit in vertically, with the screen facing up. Auto-tuning PID cooling/heating control I understand that water leads heat away, but is it supposed to loose more than 10c? The required parts are a PID controller, a solid state relay (SSR) preferably rated for 40 amps, a K-type thermocouple, a thermocouple adapter to connect the thermocouple to the Gaggia boiler, wire rated for mains voltages as well as some smaller gauge 12 volt wire, male and female quick disconnect connectors, spade connectors, and two piggyback spade connectors. This process involves working with potentially lethal mains-level voltages. And this is the thermometer out the back. I am thinking to upgrade my classic pro more compact version with below controller. Showing all 6 results. Range: -1999 to 9999 (depends on the input signal) Ive set the Sn value to pt for the PT100. Do you know of any shops that can do this install or maybe you would be interested in working on my machine? Close the PID enclosure, and attach it to the side of the Classic. I figured a video about this could be of interest to you, so here's the link: Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. This resulted in the PID not powering up even though the machine did. This does mean that you can only fill the water tank by pulling it out. Is it possible to do this with the GC factory temp sensor? The PID gives you consistency. The PID has been setup with values for Kp, Ki and Kd that work adequately but you may want to adjust them to suit your needs. Ill verify the cable, its one of the cables that came with the machine, so it could likely be the strands have slowly burned with time and just needs cutting and re-crimping, as you mention. 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! I just finished installing the PID hardware in my Classic Pro today. Even with a perfect offset, you would also need to also take into account the temperature offset between the boiler and the portafilter. The REX-C100 should work out of the box, set for heating mode, with alarms disabled, and units set to Celsius. Hello, thanks for the nice and valuable text. The microfoam created by the commercial steam wand is tight enough for high quality latte art. After autotuning, my values are: Pretty much any material should work fine as the outside of the Gaggia never gets hot enough to melt most thermoplastics. This wont be enough for the boiler heating element. Gaggiuino started as an idea to improve an already capable coffee machine while keeping the machine appearance and button functionality as close as possible to the original. Other than that mine was a fairly straightforward procedure with no trouble at all. 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. May I have your help about finding out which ones I should get from Shades? For the melted connector plastic, thats a sign of either a wire or a connector that is carrying too much current for its rating, or most likely, a connection between the wire and connector that is not as solid as it should be. robert kujawa 348 subscribers Subscribe 85K views 1 year ago In this video I'll install a PID unit on my. Im so thankful for this. TopBox with logo : Less than ten left Tap the switched hot/load mains power: disconnect the lower left-hand (if facing the front of the machine) wire from the power switch. Hi Paul. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. I double checked all the wiring (inside and outside of the chassis) and eventually came to the conclusion that I had a faulty PID. Awesome guide! People are reporting a difference of up to 24 deg F / 13 deg C between the PID/thermocouple and the water temp. 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. Thanks. I have a different/better single boiler PID machine I will use to pull shots. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. Hi Ray. You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. Connect the +/- leads from the PID to the SSR input terminals, paying attention to the polarity as these are DC. I should pointed out that the temperature ranges I was referring to were with the -8C offset on the PID. gaggia_classic_pro_pid. Please make sure you've downloaded them prior to uploading the code to your Arduino of choice. Hello. Trim, terminate and connect the wires you routed out the back of the Classic to the PID. Hi Miguel. Hi Rusty. The MCP9600 board is fastened with a screw to the small ledge inside the 3D printed box. The PID switches the power to the boiler heating element on and off a lot more frequently than the original mechanical thermostat. Keep the thermostat, in case you want to return the Classic back to factory condition. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. Marca: Gaggia: Capacidad: 72 Onzas: Color: Acero inoxidable cepillado: Dimensiones del producto: Tags Gaggia Classic Pro Tool Holster. . Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) The kit looks a lot like the one I ordered. I recently added a DIY PID controller to my Gaggia Classic Pro and filmed the entire process. I adjusted the calibration offset on the PID +5.5 degrees to read 212 degrees.Have you any suggestions of more accurately calibrating the PID and TC? Main Feature. My plan is to install the Rex C100 first using your instructions. To set the target temperature, press the 'Set' button on the front of the panel. 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. This would explain the constant switching on and off. Same with the adapter screw. My next thought was that the controller wasnt reading the correct temperature. 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. In mine, correct terminal was crosswise of yours. You can use the sensor reading on the PID display to know when to start steaming. Ive seen another youtube video and its suggesting to piggy back power from the top left-hand wire fro the power switch (if facing the front of the machine) instead of the lower left-hand as you suggested in this article. The LED on the SSR is functioning but no current can be seen. I opted to follow my connections according to your picture, rather than that text. 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. Im sorry about that, Eric. I would be glad if you have any recommendations. 1. What you describe looks very much like the steam thermostat cycle. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. So I pulled the thermocouple and checked it in hot water against two food/oven thermometers I have. I dont own a multimeter. Hi Murat. 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. I placed the SSR toward the left side of the back panel if facing the front of the machine. PID example MAX31865 driver is finished. Hi Anton. 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.
