have you had any issues with the k type or have heard of this? Note that my mod is to a Gaggia Classic, not a Gaggia Classic Pro. Stock situation: Silver case : Last one or two!!! I actually ended up getting the one you recommended. Since I cant control that, if you want to use it, you will have to parse the data: each line, after the headings, should start with the PID parameter (P, I, D) followed by the reaction of the controller. The digital LED display module is available in red or white. Pull off the steam knob and disconnect the steam wand. You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. Hi Paul. If you can share a picture of it, or a link, I can add it to the article. Users needto disable the parameter Tp, Td, and only useTb as a shot timer to pump a specific time. Thanks! Its getting very hot indeed so turned it off. Both shades and auber use the alarm 1 & 2 though with different PIDs for steam with upper limit & lower limit. Likewise, you can use 22 awg for the connection between the PID and the SSR. The operation is the same as the unmodified Gaggia machine. if i understood not adding a steam will give better steam? There is no 12v anywhere in the GCP, its all mains power inside. Heat the shrink tubing. I have to turn the set point on the PID down to about 85C to stop it boiling and getting steam and a great deal of sputter out of the portafilter. Spent a relaxing boxing day fiddling around with this mod. The kit installation is fully reversible. Hello again, I found out that connection I made was wrong. When the temperature stabilizes to within 1 degree of the target temperature, the auto-tuning is complete. 1 RELAY alarm: Normal open, capacity 250V/3A AC or 30V/3A DC And this is the thermometer out the back. Your email address will not be published. Feel free to hang out, learn a bit, meditate, ride a bike, or perhaps it's just time to move on. I deliberately avoided looking at the Mr Shades kits and instructions when I wrote this article, I dont want to steer people away from them. 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. 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. 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/. You should see no or very low voltage between neutral and ground, and you should see household voltage between the hot/load and ground. If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. This is not a difficult mod. 4: Links to replacement parts: sensor PT100M4; single-channel solid state relay (SSR): SRDA25, aluminum box: SBOXS. The C100 steps down mains voltage to 12v to power the SSR. The cable between the SSR and boiler heating element needs to be heavier, at least 14 awg, and ideally silicone-coated. What is your coffee bean dark or light? PID temperature control kit for Gaggia Classic Pro 2018+, Classic & Home. If you really want these features, its probably time to think about upgrading your machine. Ive set the Sn value to pt for the PT100. Try powering the PID directly from mains power, with just the thermocouple connected (disconnect the SSR). One end is connected to the mains connector at the back (where it is showing N sign), the other end is connected to the back of the on off switch (as you showed on the picture above). Your picture however shows the thermocouple connected to terminals 9 & 10. I had to manually enable autotuning on my REX-C100 and i dont know if other values are screwed up or if its something else, since it really does seem like the boiler is getting power in bypass of whatever the PID is doing. This is probably the most difficult part of the installation. $136.08. I have to mention that coffee taste is good, not harsh or bitter. What you describe looks very much like the steam thermostat cycle. Hi Brian. Thanks. $285.00. best part it is inexpensive and as easy as OPV mod, here are the links: 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? The PID switches the power to the boiler heating element on and off a lot more frequently than the original mechanical thermostat. Log in or sign up to leave a comment. 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. I hope you enjoy your upgraded GC as much as I do mine! I am beginning to suspect that Gaggia created as many combinations of wiring configurations and colors as they made machines. (To be certain, the M4 is the correct one). I hope it helps some EU folks not spending extra hours on debugging this minor EU-US model difference . I would not make it without you. What you describe is pretty normal, except that I am a bit surprised that your steam drops temperature down to 102. 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. share. I have installed the supply cable for PID unit using piggyback spade connectors. GAGGIA CLASSIC - MODDED. Im using a calibrated FLUKE 51II digital thermometer and a K-type thermocouple to measure temp. 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 installed an Auber PID on my Gaggia Classic earlier this year. Maybe Im missing something? I bought the PiD from Amazon referenced in a comment above and its working fine. Read More. New to the forums, but I've been experimenting with espresso at home over the last year when my brother gifted me a used Gaggia Classic with an Auber PID. (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 have couple of concerns with this setup and would like to kindly ask for your opinion: 1. Rancilio SilviaPID. There is definitely a falloff from the temperature reported by the thermocouple at the boiler and what you will measure at the group head. This feature allows you to operate the brew pump manually, with the timer as a reference. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. Make sure that all the new and repositioned wires are cleanly routed away from the boiler and pump and any uninsulated connectors. Anyway, thank you Chris. different wiring though. Main Feature. Here are a couple of examples: Hi Chris, the PWM needs a new wire to the where the pump wire was disconnected. You can search on Reddit, a few people have made these modifications. If you want to defeat this feature, please add this optionto your order. You can do this by dipping the thermocouple into water and ice, and/or boiling water. Hey. Hi Evan. Ill try to get a new thermostat from a reputable place, see if that solves the problem, and if it remains then something else in the machine is wrong. Id really love to do the install, however I have ZERO experience in electrical installation. 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. I plan to do this shortly for my old gaggia classic. Thanks for the catch, I will correct the article. https://www.auberins.com. 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. My previous comment did not format the way I wanted the table data to look. Does this pid control both the group head water and steam wand? 1. Theres also a M4 connected thermocouple wire on Amazon that arrived fast although it increased the whole cost compared to Bangood.

These set the parameters and algorithms that monitor and control. Hello, thanks for the nice and valuable text. 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). Neutral is the return path for the hot or load wire. Perfect, came back here to ask this question! Shades. It is suitable for other colored espresso machines. Thank you for making it. Is this just a matter of adjusting the offset of the PID? These are located around the shower screen. 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. But Ive downloaded the wiring diagram for my machine. Hello Chris, After all this, I found that with the PID setpoint set at 94C, the brew temperature would rise to 94.5 and fall to 92.5 minimum. Also really awesome write up. Not sure why that was the case. I had no issues with the K type thermocouple. European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. 100% Upvoted. 0. Thanks, David. however the one SSR is nice and the modification gives upgraded steam with the solder mod. 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). This guide explains this well, and also explains what to do if your home wiring is not correct: https://diy.stackexchange.com/questions/195229/in-a-light-switch-how-can-i-tell-if-the-black-wire-is-really-hot-and-the-white. One question, Ever thought about adding a pre infusion feature? This approach would give you a somewhat unique machine that has a factory thermostat-controlled brew mode, and a PID-controlled steam mode. The way I wired the PID leaves it powered on as long as the main power switch is on. That controller is an interesting find. Based on several comments, the wiring varies between units, even though they are the same model. Add to cart Buy Now. 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. All buttons on the Gaggia machine function the same way as they were. 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. Unfortunately, I didnt measure any temperatures for the un-modified machine. This PID controller kit is designed to retrofit into the European Gaggia Classic espresso machines made after 2015 (model# RI9403). BREWING UNIT RE-SETTING AND CLEANING. I am not sure exactly what you did when you moved the wires terminating on the bottom of the power switch. You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! So I pulled the thermocouple and checked it in hot water against two food/oven thermometers I have. 6 Reviews (6) $375.00. Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. Let me know your thoughts !!! I agree, the PID is a gamechanger. No gross taste. It is still showing the M4 screw as the Crossed out/wrong one, and can be a bit confusing. The on/off temperature can be adjusted by the user. I just finished installing the PID hardware in my Classic Pro today. If the wiring was done correctly, the PID should power up when the Classic is turned on. 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). Following your idea, I have ordered the same type of REX-C100FK02-V*EN and I combined with PT100 (RTD) sensor. Possibly not the optimal position but was really easy to install and I knew Id only be getting a relative indicative temperature anyway. Most thermocouple calibration articles that I have read use ice water to calibrate to zero degrees C because the boiling point of water varies with altitude. Check for wire that might have been too aggressively stripped, where some of the conductor might have also been cut away. 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. Home; Search; Log in; Sign up; Updates: Click here to visit our store! Hi Chris, i noticed you used the K type thermocouple with the M4. Net Weight: about 150g The pump can be stopped at any time by pressing the ">" key a second time. I have a 2012 and am wondering if you had success and if the wires are as described in the article. 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. 19K Items sold. Auber Instruments PID Kit for Gaggia Classic quantity. Cross referencing with the with the manual confirmed that the stickers had been reversed. Contrary to the Gaggia circuit diagram, Black is live, White is neutral, a minor issue. Before replacing the thermostat, maybe check whether your PID and thermocouple are calibrated, before committing to buying more parts. Perhaps you are refering to the video by Damian Witonski. Manual Machine Shop. Hi Jimmy. That is indeed not normal. Hi Murat, I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. However, depending on the seller, some settings may need to be changed. 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. I have changed the default value of the SL parameter to work with the RTD sensor (K thermocouple was default). Did I miss any other kits? I have a 2013 Gaggia Classic. Fast, Free Shipping. Awesome PID installation guide! I'd like to increase the brew temp a couple of degrees but have no idea how to do this. The default target temperature on the PID will almost certainly not be correct. These connectors are hard to reach, and are on very tight. You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. Consult the instructions that came with your PID to make sure. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. This is because the switch is connecting the terminals vertically when it is turned on.

Shall I connect it to terminal 5 or 2 of the on-off switch? Hi Brian. Without offset the range is between 109-159, still too low. The PID works after hooking everything up. Main Output: SSR: Open circuit: 4V, Closed Circuit: 24V40mA DC The steam temperature controlallows the boiler temperature to be held at a tighter range during frothing. I would not try anything without checking first. Users can see the boiler temperature on the PID controller directly and also easily adjust the brew water temperature to suit their own tastes. Im wondering if this could somehow be the outcome of a bad SSR: Im not seeing current flow between the two AC terminals of the SSR when the PID is attempting to heat the boiler to the Set Temp. Did you have any problems or stumbled upon anything unexpected? Thanks! Thanks. This is a Used Black Appliances for Sale in Fairlawn OH posted on Oodle Classifieds. If you really want to avoid the heating element switching while youre pulling a shot, you can blip the steam switch for a few seconds before brewing and that will bring the boiler temperature up a few degrees. () . K type thermocouple, 0-500, 2m cable (6 feet). Started by Rocky47. Some shops are quoting $80.00 for the PID enclosure + lid. Each segmentcan be set by the user with 0.1 seconds resolution. 3. If you also need features such as steam temperature control, pre-infusion, and countdown timer, please checkKIT-GGPpre-infusion kit. Approach 1: Follow my writeup, adapting it to your models peculiarities, and then set the PID temperature to your preferred steam temperature. 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. It will improve the consistency of the brewing even if you didn't tamp the coffee perfectly. https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd.
