To be clear, a PID can increases the likelihood of a consistent starting temperature. Thanks again for all your support. 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. Hi Chris, After completing the PID installation, of the standard Rex c-100 version, I ran the PID in autotune mode. Any ideas? Glad you got that sorted out. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. 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). Also really awesome write up. It will depend on the beans you use, and your palate. I drilled pilot holes for all the screws because my 3D printer has problems printing holes that small. 4.6 de 5 estrellas 1,758 calificaciones. Thanks! Steaming will remain controlled by the Gaggia's stock thermostat. Plug in a mains-rated cable connected to a piggyback spade connector, and then plug the original switched mains cable into the piggyback. I printed everything using Inland PLA+ filament. gaggia_classic_pro_pid. You can use the same 18 gauge wire between the heating element and the SSR. This works well with a PID for light & medium roasts. Im sorry about that, Eric. To set the target temperature, press the 'Set' button on the front of the panel. 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. You can only buy them as spare parts. Note: I fully tested the PID, SSR and thermocouple on the workbench before final installation. So there is more or less no concern about PID heat and the PID enclosure. Either way, you are looking at a lot more complexity and cost. New - Gaggia Classic Pro/2019 PID kit - 1/32DIN single display $139.33 excluding VAT View Product Information Select Your Mounting option Silver case Black case TopBox with logo TopBox with gauge hole Stock situation: Silver case : Less than ten left Black case : Last one or two!!! You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. Chris, i read some comments here about steam. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright . Or is the only power available from the mains? Does the PID generate enough heat to melt the Lego bricks? Hi Justin. 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 Gene. Im all for freedom of expression and creativity, but not when it might electrocute someone. Perfect, came back here to ask this question! Apart from that, when I turn on steam mode, the thermostat takes temperature in the machine around 151c-152c, it doesnt turn on again after it goes down to 102C, then turns on and repeats the cycle. Hello Chris, Please make sure you've downloaded them prior to uploading the code to your Arduino of choice. The Gaggia Classic is a very capable espresso machine that gets even better with a couple of improvements. https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd. The PID switches the power to the boiler heating element on and off a lot more frequently than the original mechanical thermostat. The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. Thus brewing circuit needs to be connected directly to the heating element, not over steaming circuit. Works on both US 110V and EU 220V machines.Parts existing in the video:LED light kit: https://coffee-sensor.com/product/gaggia-classic-or-pro-water-tank-led-. Let me know your thoughts !!! Marca: Gaggia: Capacidad: 72 Onzas: Color: Acero inoxidable cepillado: Dimensiones del producto: you could use this guide on another kit as all of the pieces here are required for just about any pid. I was originally going to go with the gaggiuino, but this PID and dimmer mod are 100x easier But it will require some dismantling of the work you have done. Warning! 1. This would explain the constant switching on and off. 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. However, depending on the seller, some settings may need to be changed. add to list. I have not changed any of the P, I or D settings on my controller. I also cleaned the part of the group head that that gasket sits in. Close the PID enclosure, and attach it to the side of the Classic. I havent lowered brew pressure to 9 Bars yet so perhaps changing that would level out my pump pressures? Theres also a M4 connected thermocouple wire on Amazon that arrived fast although it increased the whole cost compared to Bangood. I should pointed out that the temperature ranges I was referring to were with the -8C offset on the PID. Its pretty straightforward. AC CIRCUITS ARE DANGEROUS AND MISTAKES CAN CAUSE INJURY OR DEATH. It just overrides the PID and heats up the boiler to the factory preset steaming temperature.Links to parts [None are affiliate links]https://bit.ly/3gL9c95 - XMT 7100 PID unithttps://bit.ly/3xgAHhc - PT100 precision temperature sensorhttps://bit.ly/3wnZD6l - Fotek solid state relay 25Amphttps://amzn.to/3xamPFg - cable sleeve (different widths available)https://amzn.to/2RSAge0 - magnetic tape (example link, different widths available)https://www.thingiverse.com/thing:3671244 - 3D printed case file (print this locally)https://bit.ly/3pPphP0 - the unattractive aluminium enclosure if you wish to go that routeYou will also need:1. 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? Gaggia Classic Mods PID kits, OPV kits, and other mod kits designed for various Gaggia espresso machines - drill down into kits relevant to your model of machine. 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). I also checked to ensure that the physical steam switch is functioning correctly and the circuit is broken when it is off. I would not try anything without checking first. I have re-read the specifications for this controller. You wont need the heat sink, the GCs case does that job for you. Have you written an article regarding installing a Gaggiuino mod? 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. Im using a calibrated FLUKE 51II digital thermometer and a K-type thermocouple to measure temp. Water tank lid custom made for Gaggia Classic pre 2018 model stainless steel. You could approach this two ways. have you had any issues with the k type or have heard of this? Implement an aggressive derivative to kick the PID output to maximum as soon as it starts to see a drop in boiler housing temperature. This was such a great guide. With a SV of 103C (not offset), during initial overshoot the heater would sometimes be one when it was at 104-105C with the temperature rising as high as 108. Awesome guide! The most I can say is these work for me, and are probably not optimum. Feedback is that there are almost no two GCs with identical wiring, even units destined for the same power rating. Once you are able use the PID temperature readout to determine exactly what the steam cycle is, you know when to start steaming for more or less endless steam. It should be placed as close to the left-hand side of the Classic as possible. Hi Jeff. If youre not comfortable installing this yourself, and taking on any followup maintenance, I think you would be much better off purchasing a machine that comes with a PID from the factory. Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) Applications How to install a pid on the gaggia classic pro. Heat the shrink tubing. My next thought was that the controller wasnt reading the correct temperature. I know what I will be trying tomorrow , Hi, 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. 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. It would be great to see how the machine is behaving without the PID, to get a baseline. 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. it appears i can configure the BERM REXC-100 like this as i entered the settings after i enabled alarm 1. auber uses 1 SSR & is simple. No gross taste. I am now waiting for my PID unit and thermocouple with M4 head to arrive this week. The PID works after hooking everything up. Most likely will work on the Silvia as well. I tested the current with multimeter and it is showing DC 100V when I turn on the on-off switch. PID, Auto Shot Timer Add to Watch list. Hi Tom. 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. Although this is optional, it is difficult to access the power switch to tap power for the PID, and it is almost impossible to reach the thermostat without moving the boiler, and the boiler cant be moved unless the steam wand is removed. Wire colors and positions seem to vary. Mounting Dimension: DIN: 1/16 (48mmX48mmX80mm) Use Git or checkout with SVN using the web URL. 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). Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. Only needs 2 x AAA batteries. They are easy to unlock to get to all of the other settings, there are plenty of instructions on how to do this out there, but I didnt really need to go there. Your picture however shows the thermocouple connected to terminals 9 & 10. 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. however the one SSR is nice and the modification gives upgraded steam with the solder mod. YOU ALONE ARE RESPONSIBLE FOR YOUR OWN SAFETY, PLEASE KNOW YOUR LIMITS. After autotuning, my values are: You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. The microfoam created by the commercial steam wand is tight enough for high quality latte art. 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. . I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. I can actually taste the sweetness for the first time. Your email address will not be published. Gaggia Classic Pro PID Installation #5 - I have power! Despite the K02 indicating K-type, it was advertised as supporting multiple types including PT100. Hi Brian. Realized with your last comment you dont have the offset in place, my bad. auber pid kit gaggia classic. Chris has done a great job on this write up and its easy to follow. Due to your kind and quick advice, I could order SSR40DA. The same complexity applies to pressure control. Hi Brian. Its crazy. This is really a DIY project. 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. Hi Chris, I am gathering / ordering the parts specified and was surprised to find out the price for 3d printing price spiked. The PID values are not saved if you change them through the menu so if you find a tuning you like and want to change the defaults, you'll need to do that in the code and then re-upload it to the device. Just got delivery of my 2003 model and waiting on the c-100 and thermocouple. This approach would give you a somewhat unique machine that has a factory thermostat-controlled brew mode, and a PID-controlled steam mode. Hi peeps, finally got all the bits n pieces to do the Pid, brew & steam mod on the gaggia, does anybody have any general instructions for putting this all together?
