gaggia classic pro pid installgaggia classic pro pid install

Where did you place the SSR? Hi Chris, I appreciate your tutorials on the PID install. So there is more or less no concern about PID heat and the PID enclosure. Sure enough, it powered up. The image I used is wrong and confusing, and I have now updated it. Would you be able to post starting values for the PID kit please? Have you noticed any problem using REX-C100FK02 and RTD PT100? 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. Do you think this makes difference? Based on several comments, the wiring varies between units, even though they are the same model. That controller is an interesting find. You will probably want to drill pilot holes as well to prevent cracking the plastic. I agree the ability to know exactly where the steam cycle is at is a nice convenience. Well I ordered the wrong thread. Brilliant article. Also some pids come with a built in relay. 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'teki stma sistemi basit mekanik termostatla altndan scaklk 85-105 derece arasnda gidip geliyor ve siz demlemenin hangi scaklkta balayp hangi scaklkta bittiini bilemiyorsunuz. However, when I flip the gaggia power switch to off, the PID LCD screen remains illuminated. One bit of note and a request. When I say old, it is still unused new in the box. You should see a strange number when the PID first powers on, then after about 3-5 seconds it should switch to the temperature reading from the thermocouple. When the PID signals the SSR, as indicated by the brew ready light and the output led on the PID, the pressure coming out of the pump decreases, and then increases again after the PID out to the SSR turns off. Hi Chris. Its crazy. When set up on my bench it tucks away nicely in behind out of sight and only needs to come out when in use. 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. As you'll see, it isn't that complicated and really takes the humble Classic to a higher level!00:24 - Introduction02:10 - A list of parts05:58 - What NOT to do first06:50 - Disassembling the machine09:27 - Installing the temperature sensor10:55 - Making connections15:10 - Installing the solid state relay18:44 - Tidying up the cables20:01 - Connecting the PID22:45 - Cost summary24:15 - Autotuning24:51 - Was it worth it?In contrast to the most popular solutions in the market, my PID will sit at the back of the machine and be no bigger than the unit itself. Heat the shrink tubing. This was built on an Adafruit Metro Mini, which is directly compatible with the Arduino Uno R3, but you can use any Arduino board as long as it has enough pins and it supports I2C. You should be done! Did you have any problems or stumbled upon anything unexpected? Hi Chris The SSR is only rated for 5 amps. Remove the portafilter and water tank. I dont bother with offset, once I have a temperature dialed in, it doesnt matter whether its measured at the boiler or offset for the group head. 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. I printed everything using Inland PLA+ filament. I have a 2012 and am wondering if you had success and if the wires are as described in the article. Privacy Policy. Thanks so much for the awesome guide! A couple of zip ties come in handy here. 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? Im in North America btw. 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? YOU ALONE ARE RESPONSIBLE FOR YOUR OWN SAFETY, PLEASE KNOW YOUR LIMITS. This works well with a PID for light & medium roasts. 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. The C-100 that I received was set up properly, I only had to change the temperature. Recently purchased and upgraded Gaggia Classic Pro from Whole Latte Love in late November, and built/installed the Gaggiuino mod myself in February. Gaggia Classic Pro DIY PID controllerGithub page with firmware for ESP32 - https://github.com/tosteich/Espresso_PIDSome pictures of internal setup - https://. MY GC does the same thing, the pump tone changes when the boiler is heating. add to list. The OLED and buttons can be secured with your favorite adhesive. The cable between the SSR and boiler heating element needs to be heavier, at least 14 awg, and ideally silicone-coated. Slip some heat shrink tubing over the thermocouple, and ideally dip the thermocouple tip in some thermal grease, then insert the thermocouple into the adapter. I have couple of concerns with this setup and would like to kindly ask for your opinion: 1. Thanks. I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. But just like the kit I ordered, the threads on the thermocouple M8 according to the specifications are too big for the Gaggia. Ive tried connecting these in various combinations but the PV readout is 3 or 4. 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. The YouTube video from wll about replacing the boiler made the whole thing very easy. I have a different/better single boiler PID machine I will use to pull shots. I formatted the table, its very useful. Hi David. shades uses 2 connecting one ssr thru the other for steam. The value proposition goes right out the window at that point because you're now at nearly $700 if you bought the machine new. From what I have read, the PID with the additional steam mode option does not improve things much. Neutral is the return path for the hot or load wire. Range: -1999 to 9999 (depends on the input signal) Final note: before going down the PID route, the easiest modification to make, and the best starting point for Gaggia Classic modifications, is lowering the brew pressure. Hello Chris, add to list. The microfoam created by the commercial steam wand is tight enough for high quality latte art. This is because the switch is connecting the terminals vertically when it is turned on. The PID gives you consistency. I was able to create one using Lego bricks sitting around in the basement. Because there is very little information on how to install a PID on the latest generation of the New Classic (2018 and newer, also called the Gaggia Classic Pro in North America), here are instructions on to do this. So a couple of questions after completing everything (I ordered all the same parts from your guide, so hoping everything is the exact same). Im all for freedom of expression and creativity, but not when it might electrocute someone. My next thought was that the controller wasnt reading the correct temperature. 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. This video clearly shows how to program in an offset on the Rex C-100: https://youtu.be/9aW8MfiKIPg?t=291. The thermocouple should be snug but not too tight as the threads are not super robust. An extended de-bugging solved the problem: the PID 12v circuit output was reversed, so changing + to solved the problem. 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). How to install a pid on the gaggia classic pro. Current Status. Just installed the PID kit from shades of coffee, i configured it to 93c but when i turn the brew switch on, the temp doesnt stay at the +-1 tolerance. If you used piggyback connectors, it should be a quick job to move the right one over to the correct switch terminal. Trim, terminate and connect the wires you routed out the back of the Classic to the PID. 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. 4.6 de 5 estrellas 1,758 calificaciones.

So I would say yes, you should use a heat sink, but the Gaggia body conveniently provides you with that function. I used lamp cord for this. You can take a look at this discussion about offset in the Gaggia Classic: https://coffeeforums.co.uk/topic/53319-what-temp-offset-are-you-using-with-your-pid/. You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. ESP32 IO. Thanks Alex! This design is intended to be as simple as possible in terms of the installation, and requires minimal modification to the Gaggia machine. PID interface for the Gaggia Classic Pro. In mine, correct terminal was crosswise of yours. This is VERY important! Input. Hi Anton. That is confusing. The listing shows both M3 and M4 options, and I typed the first one when I wrote the article. The little red collar shows the location. When I got my C100 the thermocouple was M6, i ended up buying an m4 brass bolt drilling it out, and inserting the thermo with some glue and heatshrink on it and it works like magic added some thermal paste. Hi Jun, and thanks for the update. Hi Murat. Is there an easy way to set a brewing and steam temp? 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. My P value is quite a lot different than yours. Maybe Im missing something? Hello, I acquired and prepared all cables and SSR unit thanks to your well prepared title above. Do you know how to do this? It really pays off to assume nothing, and test everything. Thanks again for the write up, Ill be playing around with temperature for the next week! As for your PID always remaining on, it looks like you wired it to the unswitched mains, instead of the switched power. Is there a way to tap into +/- 12Volts inside the GCP? Nevertheless, I will take a look and see what values my controller is set to. Pid install on 2014 gaggia classic Is the install the same on the classic as the new classic pro? Perhaps Ill use a spare Arduino or FPGA to PWM the boiler while brewing as someone else was saying. Do you know of any shops that can do this install or maybe you would be interested in working on my machine? Finally got around to upgrading my gaggia pro to having a PID! auber pid kit gaggia classic. When I turn off, it goes back to zero. Do not work with the Classic plugged in. Id really love to do the install, however I have ZERO experience in electrical installation. Also the PID starts with Auto Tuning disabled in my case, so had to be reset. Gaggia Stainless Steel 2 Cup Filter Basket with Pin Pressurised Crema 21000491. I did that exercise before installing the PID, behavior should be identical as that time. Only needs 2 x AAA batteries. You can only buy them as spare parts. Please be sensible and install a grommet anyway! These are located around the shower screen. Due to your kind and quick advice, I could order SSR40DA. If the wiring was done correctly, the PID should power up when the Classic is turned on. https://www.vertex-qis.co.uk/Manuals/PT100_con.pdf. Whole Latte Love has a new video about preinfusion on the classic. 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. To set the target temperature, press the Set button on the front of the panel. What exactly is a mains-rated wire, and where would I find one? The idea of the chassis becoming live doesnt bear thinking about. Spent a relaxing boxing day fiddling around with this mod. Other than that mine was a fairly straightforward procedure with no trouble at all. This is not a difficult mod. I decided to go the do-it-yourself route, ordering the parts separately, at a fraction of the cost of the kits. great article !!!! AC CIRCUITS ARE DANGEROUS AND MISTAKES CAN CAUSE INJURY OR DEATH. It also means that you can only see the temperature and access the PID buttons from the top. Hi Chris, Its pretty straightforward. Hey Chris, To be clear, a PID can increases the likelihood of a consistent starting temperature. Feb 12, 2021. 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). Hi Joe. Free shipping.
