Do not work with the Classic plugged in. The only way to cut it is to unplug the machine. Thanks, David. Im so thankful for this. Thanks in advance for any reply! 3. Thank you for your time. Thanks. In the text it says M4, but on the picture, it highlights to use the M3. Did you reverse any wires to the steam switch? 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. My problem is, unlike Rancilio Sylvia, heating element of Gaggia Classic Pro seems impossible to connect without cutting cables. Any ideas? Glad this writeup helped. Same with the adapter screw. Also, the PID generates almost no heat, because the work is done by the SSR, and this is heat-sinked to the Gaggia. This video covers initial setup of the Gaggia Classic Pro espresso machine. Does anybody have a Shades of Coffee pdf for the brew and steam setup on the gaggia classic, mines a 1998 classic coffee model, it would be much appreciated. Connect the +/- leads from the PID to the SSR input terminals, paying attention to the polarity as these are DC. 1. I tested the current with multimeter and it is showing DC 100V when I turn on the on-off switch. Individually PID control parameters The only other thing I can think of is the relay. I was originally going to go with the gaggiuino, but this PID and dimmer mod are 100x easier However, when I flip the gaggia power switch to off, the PID LCD screen remains illuminated. Is this a typo on your part or a mistake on their part? There was a problem preparing your codespace, please try again. Not sure why that was the case. Accuracy: 0.2% I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. Its threaded on, and should not be very tight. This is the setup that I have assembled two days ago. I was able to create one using Lego bricks sitting around in the basement. Im in North America btw. Hello again, I found out that connection I made was wrong. You should now have two mains wires, two 12 volt wires, and the shielded thermocouple wire running out of the back of the Classic. Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. I also think that you may have less difficulty reaching the thermostat, the 2019+ models have a lot less room to spare inside. You need a 85-250V DC model, as the power will be coming from the Classic, which is mains-level voltage. shades uses 2 connecting one ssr thru the other for steam. + $55.24 shipping. Also really awesome write up. I drilled pilot holes for all the screws because my 3D printer has problems printing holes that small. 102 is way too low, you wont get useful steaming at that low a temperature. Take your time, think it through, and be patient. Gaggia Stainless Steel 2 Cup Filter Basket with Pin Pressurised Crema 21000491. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. add to list. Gravity seems to be working as expected in my case but you may decide to attach a magnet to the side of the box that touches the Gaggia for a more secure mount. Its stimulated a lot of interesting discussion! Hi Andrue. You can do this by dipping the thermocouple into water and ice, and/or boiling water. I have a 2005 GC with a Mr Shades PID kit installed. 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! It will also be completely reversible and much cheaper than ready made solutions!This clip can also be treated as a how-to instructional video for anyone wishing to go the DIY way. Hello Chris, You can search on Reddit, a few people have made these modifications. If you are competent with basic workshop tools and can follow written instructions and photographs then you should be able to install the Gaggia Classic Pro PID Kit in around 2-3hrs and it requires only basic tools such as: A medium flat-bladed screwdriver A medium cross-head screwdriver I have re-read the specifications for this controller. And anything is going to be a huge improvement over the thermostat that the PID replaces. So there is more or less no concern about PID heat and the PID enclosure. 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. Apologies for the long questions, thanks in advance! Maybe this will help? 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. 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! The lid of the enclosure is held by four screws. 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. Main Output: SSR: Open circuit: 4V, Closed Circuit: 24V40mA DC I am not sure exactly what you did when you moved the wires terminating on the bottom of the power switch. Thanks for the info, D. Your experience further goes to show that there is no standardized wire color coding in the GCP, even though black is usually hot and white is neutral. I love the Lego enclosure idea. 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). And once you start considering adding in a power supply, you might as well go for a PID. 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. Pantechnicon Wood kit installed on . 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. I have to mention that coffee taste is good, not harsh or bitter. Thank you again for taking the time to write up such a great guide. Unfortunately, no, you cant use the factory sensor. The best way to find is: 1-Connect one cable to the mains connector at the back where it is showing N sign meaning Neutral. My plan is to install the Rex C100 first using your instructions. Hi Jun, glad you found this helpful. - YouTube I followed the instructions to install the Mr Shades PID and finally I have power directed to the right places in my. Drip Tray Grid Gaggia Classic (pre 2018 model) Straight Lines from Stainless Steel. I agree, the PID is a gamechanger. Is this typical? 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. Marca: Gaggia: Capacidad: 72 Onzas: Color: Acero inoxidable cepillado: Dimensiones del producto: Please note that I'm only using the PID to control the brew temperature. To set the target temperature, press the Set button on the front of the panel. The cup warmer does seem a bit hotter than before (but have only used twice since installing, so Ill have to pay attention). Did you make any changes to the setting of the PID? Great guide. It doesnt matter which mains terminal is connected to hot and which one is connected to neutral. 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. It doesnt matter which thermostat wire is connected to which of the AC terminals on the solid state relay. If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. 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! 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. PID kit temperature control for Pavoni or Faemina lever coffee machine . My P value is quite a lot different than yours. 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. Cookie Notice Mechanical Rocker Switches if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple. Thanks. Using two 5-8 cm pieces of properly-rated wire (15 amps for North America), make two connectors to connect the thermostat wires to the AC terminals of the solid state relay. It heats up to 93 +-1c and then goes down as soon as i hit the switch brew. Hi Chris, I appreciate your tutorials on the PID install. It will depend on the beans you use, and your palate. Yesterday I replaced the group head gasket. Whole Latte Love has a new video about preinfusion on the classic. Note that my mod is to a Gaggia Classic, not a Gaggia Classic Pro. if i understood not adding a steam will give better steam? Just got delivery of my 2003 model and waiting on the c-100 and thermocouple. 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. Hi Jun, and thanks for the update. Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! D 9. This works well with a PID for light & medium roasts. 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. When I say old, it is still unused new in the box. It also means that you can only see the temperature and access the PID buttons from the top. Bliss. By accepting all cookies, you agree to our use of cookies to deliver and maintain our services and site, improve the quality of Reddit, personalize Reddit content and advertising, and measure the effectiveness of advertising. 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. Im thinking Id like to start with just a temperature indicator, to assist with the surfing. Hi Chris, i noticed you used the K type thermocouple with the M4. The boiler had been installed in such a way that it had pinched/nearly severed the upstream wire on the brew light. But Ive downloaded the wiring diagram for my machine. The LED on the SSR is functioning but no current can be seen. Gaggia Classic OPV spring mod kit - Standard version (just springs) $12.78 Shades of Coffee Slim drip tray complete with long vent tube for Gaggia Classic $30.67 Shades of Coffee Bottomless Portafilter with walnut wooden handle (smooth) - for Gaggia Classic / Classic Pro $42.17 Shades of Coffee Warning! 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. 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 was such a great guide. Due to your kind and quick advice, I could order SSR40DA. Gaggia Classic Coffeemaker Coffee Drink Food and Drink comments sorted by Best Top New Controversial Q&A Add a Comment More posts you may like. In a properly wired North American outlet, the neutral wire is white, and the hot/load wire is black (ground is green). I have few questions for you about this setup. To do that I turned the machine upside-down. it does not matter if the bean is dark or light roast? 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? For the wiring inside the PID I just used 32AWG single strand hookup wire and for any wiring inside the Gaggia I used silicone insulated wire (26AWG for the wiring from PID to SSR, 12AWG to extend the thermoswitch leads to the SSR as referenced in the Installation Steps below). Finally got around to upgrading my gaggia pro to having a PID! 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. Chris, this is a far simpler way to add preinfusion. THIS ASSUMES YOUR COMPETENT WORKING WITH AC CIRCUITS. Gaggia Classic Pro DIY PID controllerGithub page with firmware for ESP32 - https://github.com/tosteich/Espresso_PIDSome pictures of internal setup - https://. Once warmed up, the recovery time is quick and the swing is fairly minimal. The C100 is probably made by dozens of different manufacturers. Free shipping. Im sorry about that, Eric. Hi Jeff. I double checked all the wiring (inside and outside of the chassis) and eventually came to the conclusion that I had a faulty PID. Thanks in advance! . I formatted the table, its very useful. Most likely they will have the same connector types as the REX-C100, but its always possible that you will need different connectors depending on what you end up ordering. 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. Unfortunately, I didnt measure any temperatures for the un-modified machine. Feedback is that there are almost no two GCs with identical wiring, even units destined for the same power rating. 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. The microfoam created by the commercial steam wand is tight enough for high quality latte art. It is a really tight fit to get the REX C-100 PID inside the machine. If you use anything different you'll need to make adjustments to the 3D printed parts. Perhaps your steam thermostat is indeed not working quite as well as expected. 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. Thank you Chris for the awesome write up. What is your coffee bean dark or light? https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd. Is this just a matter of adjusting the offset of the PID? The lack of consistency pre-PID is frustrating, because you can get everything else right and still be at the mercy of the temperature determined by the thermostat cycle. I had no issues with the K type thermocouple. Or is the only power available from the mains? Most assembly guides recommend using some thermal paste between the SSR and the Classic to ensure that any heat from the SSR is dumped to the chassis. I have an old Gaggia Carezza (uses the Gaggia / SaecoEF0030/A Boiler). Thanks for the PID info. 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. The .ino file includes several libraries. 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. For the Classic Pro, this requires either shortening the spring in the OPV valve through trial and error, or ordering a spring kit from Mr. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. I purchased an AC to AC SSR (SSR 40AA) which will stabilise steaming temperatures in much smaller margins than the original steam thermostat. Thanks for the quick reply. Please be sensible and install a grommet anyway! 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. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. Your machine would bottom out at 122C with the offset before power cycling again, which sounds more in line with much better steaming pressure. I then thought what if? and decided to change the mains wires to the opposite terminals. The thermocouple connects to terminals 6 and 7. The PID itself draws very little current, so something like 18 gauge lamp cord would work. Print services. Thanks. You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. 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. An important part is that no internal cables/connectors were modified; all the connections were made by creating splitters using the purchased spade connectors. You wont need the heat sink, the GCs case does that job for you. Double check that this is the neutral! The PID, RTD sensor and SSR (20 Amps) are installed on Gaggia Classic Pro 2018+. Hi Kez. Thx, I figured a video about this could be of interest to you, so here's the link: Leave this cable longer than needed for now, it will be trimmed and terminated later. Awesome PID installation guide! Use Git or checkout with SVN using the web URL. Hello Chris, There are no holes in the printed parts for the wiring between the PID and espresso machine, you'll need to decide where you want these holes and drill them yourself. Fortunately, no damage done, and you can easily revert your changes. I decided that for me, its not worth worrying about. I am not surprised that the steam kit made little difference. Universal Input: Thermo Resistor: PT100, Cu50 . Perfect, came back here to ask this question! For those interested I just bought a cheap ($13) K-type thermocouple and thermometer (TM-902C) https://www.ebay.com.au/itm/224710871179. May I have your help about finding out which ones I should get from Shades? r . Run this wire along the rest of the existing cables and out the back of the Classic, through one of the vent slots. If you go for a PID, you need to use a thermocouple. Regarding the M4 screw/ thermocouple, is it possible to amend the picture? My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). Hi Brian. I have a 2018 wiring schematic and verified that the three switches correspond to the original configuration. These are located around the shower screen. Input. Look at Gaggia classic PID install instructions. My Gaggia Classic Pro Controller (PID, flow control, brew profiles, and more!) Also some pids come with a built in relay. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. Your email address will not be published. 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. 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. Its one more thing to plug in, but the upside is that it would be electrically isolated from the Gaggia. Replacing that wire= everything works perfectly now! The way I wired the PID leaves it powered on as long as the main power switch is on. START NOW 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 This is a PID controller kit installation guide distributed solely to our clients, who have purchased the KIT-GG kit. I start to run the steam at about 130 in the heating cycle on my setup. But I would definitely read the instructions that come with whatever you receive! I actually ended up getting the one you recommended. 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). You need at least 20 amps. Optionally, you can add some sleeving to the wires running between the Gaggia and the PID. If the wiring was done correctly, the PID should power up when the Classic is turned on. Hi Gene. The listing shows both M3 and M4 options, and I typed the first one when I wrote the article.
