You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. Based on several comments, the wiring varies between units, even though they are the same model. If you have a regular version that doesn't have the auto-turn-off feature, (RI9380, 120Vor 240V), you DO NOT need this piece of wire. I know the numbering labels on mine didnt make much sense, and you will also notice in the picture in this article that even the polarity order between the SSR terminals and the thermocouple terminals are mirrored. The 12 volt wires from the SSR connect to terminals 4 and 5. I think this would be the most important parameter of the build, obtaining the correct temp of the water. 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. Thanks Jimmy. This is a PID controller for the Gaggia Classic by Auber Instruments.This PID controls water and steam temperature. gaggia classic pro pid installation guideAUBER PID for gaggia classic proThis is a walkthrough / guide on ins. Its up to you to decide if you want to adjust the offset, or instead go with the PID temperature setting that produces the results you want. The installation is completely reversible if you ever want to sell the machine or send it to service. Hi Murat, GRAN GAGGIA PRIMING. It has a blue led not red like pictured.The kit works for 115 VAC and 240VAC. Or is the only power available from the mains? I recently acquired a Gaggia Classic with an Auber PID controller installed. I can actually taste the sweetness for the first time. When set up on my bench it tucks away nicely in behind out of sight and only needs to come out when in use. 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. Hi Gene. [KIT-GG] Auber Instruments, Temperature control solutions for. Regarding the M4 screw/ thermocouple, is it possible to amend the picture? 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? This is probably the most difficult part of the installation. The PID gives you consistency. Loosen the four bolts that hold down the boiler assembly. I do not suggest autotuning for this device because there is a huge improvement in temperature stability if you do the tuning by yourself. For espresso, 9 bars is the generally preferred pressure. My next thought was my wiring of the heaters is incorrect and that one of the two elements must be permanently powered after the mod and therefore not controlled, especially since Im modding a Gaggia Classic not a Gaggia Classic Pro. Hi Jeff. Display: Dual display for Fahrenheit(F) and Celsius(C) I have found the exact PID unit which Mr Shades is using and purchased it beside the Rex C100 kit you mentioned above: 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! $285.00. Approach 2: Divert from my writeup by installing the thermocouple so that it replaces the steam thermostat, and set the PID temperature to your preferred steam temperature. Specifications : It looks like your GC is in steam mode. I used lamp cord for this. All buttons on the Gaggia machine function the same way as they were. I dont own a multimeter. Hi Kez. As for you steam mode question, if you followed this guide for installing your PID, the PID will have no effect on the the steam temperatures or functions. Is this a typo on your part or a mistake on their part? Hi Miguel. I have a 2012 and am wondering if you had success and if the wires are as described in the article. I am glad you solved the problem, Murat. Realized with your last comment you dont have the offset in place, my bad. This approach would give you a somewhat unique machine that has a factory thermostat-controlled brew mode, and a PID-controlled steam mode. $326.00. The connector is on the back of the machine, where mains power is tapped with a piggyback connector and goes to the PID. Hi Brian. 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. This is sold on amazon Hello again, I found out that connection I made was wrong. Auber Instruments PID Kit for Gaggia Classic. Gaggia Babila. https://photos.app.goo.gl/Xp37S3o3y6bqqrEk8 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. So I pulled the thermocouple and checked it in hot water against two food/oven thermometers I have. LED display color. Hi Chris, http://facebook.com/HKCoffeeHome EspressoGaggia Classic !Gaggia Classic can give a good espresso shot . My only concern is the diagramm I downloaded from whole latte love shows different connections then what I have seen in my unit This PID controller kit is designed to retrofit into the European Gaggia Classic espresso machines made after 2015 (model# RI9403). 4.8. 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. This product was added to our catalog on Friday 12 August, 2011. The taste of a real Italian espresso everyday! Do you observe the same temperature ranges? Spent a relaxing boxing day fiddling around with this mod. Is there a way to tap into +/- 12Volts inside the GCP? . There are other resources online as well. If you also need features such as steam temperature control, pre-infusion, and countdown timer, please checkKIT-GGPpre-infusion kit. Hi Chris, For the European version of Gaggia Classic 2015 (RI9403, 240V) please checkKIT-GGX-EU. Wanted to double check here for some observations a about three months after installing the PID. I hope you enjoy your upgraded GC as much as I do mine! Hello, Disconnect the two connectors from the brew thermostat, which is located on the bottom left-hand side of the boiler as you face the machine. Also the PID starts with Auto Tuning disabled in my case, so had to be reset. 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. Indeed, not an option. on orders over $49. PID Kit for older plastic body Gaggia Classic. This prevents the high-pressure water from contacting the dry coffee powder which can create afast flow channel, ruiningthe brewing process. 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. Im sorry about that, Eric. 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. hide. 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. Monitor and display the boiler temperature precisely. Thanks in advance! I also checked to ensure that the physical steam switch is functioning correctly and the circuit is broken when it is off. If you need to replace the PID controller, please contact us. 1. My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). There is no 12v anywhere in the GCP, its all mains power inside. Main Feature. -. Log in or sign up to leave a comment. 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. Or buy a machine with a built-in PID. Same with the adapter screw. It will depend on the beans you use, and your palate. Hi Eddie. I think this is why using a separate SSR and controller is the only way to go. QB-T7200 48*24mm Programmable Digital PID Temperature Controller with Built-in 5A Solid State Relay XMT7100 AC/DC85~260V. Shop for it now! But this kit doesn't fit the European model RI9403, which has a stainless steel boiler with a different thermostat mounting. You are right, its an M4 thread, not M3. 3. I have a similar model, C100-Fk02-V*AN. 5: The PID controller in this kit is NOT SYL-1512A. Its threaded on, and should not be very tight. Do you think this makes difference? I strongly suggest checking which switch terminal switches the mains. The countdown extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. i set an upper an lower limit on alarms. Terrific write-up thank you for posting it! The SSR is only rated for 5 amps. The rich body and complex flavor profile of a well-made shot brings the beans to life with a depth that other brewing methods fail to achieve. 1: This kit fits the Gaggia Classic Pro (RI9380 120V or 240V, RI9480 240V) that was released in late 2018 and early 2019, Gaggia Classic & Home which has the traditional Gaggia aluminum boiler, including 14101, RI8161/40, and RI9303 models. 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. Guys, there is mains voltage here. It will improve the consistency of the brewing even if you didn't tamp the coffee perfectly. The Classics over-pressure valve (OPV) is set to 14 bars, which is a pressure better suited to the use of pressurized portafilters. Do you think this makes a difference? You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. Did you have any problems or stumbled upon anything unexpected? Also, the PID generates almost no heat, because the work is done by the SSR, and this is heat-sinked to the Gaggia. What you describe is pretty normal, except that I am a bit surprised that your steam drops temperature down to 102. Consult the instructions that came with your PID to make sure. If its closed it takes longer for temperatures to drop, but still goes to 102 before the it power cycles. Leave as much of the thermal grease in place as possible. How to install a pid on the gaggia classic pro. Thanks for the PID info. The YouTube video from wll about replacing the boiler made the whole thing very easy. UNBLOCKING. Hi Jun, glad you found this helpful. Do you think its going to blow my machine if I dont do correctly? It doesnt matter which mains terminal is connected to hot and which one is connected to neutral. Thanks, I see what you mean. Chris thank you so much. This is a Used Black Appliances for Sale in Fairlawn OH posted on Oodle Classifieds. If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. 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. Youre probably fine with either one. Is this typical? Good idea Chris. PID Modification by Auber Instruments' Customer. But nothing prevents you from using the PID and thermocouple as a temperature indicator. Awesome guide! I used the same controller ( XMT 7100 ) which Mr Shades is selling. If not, can you think of any potential mistakes I made along the way? If you used piggyback connectors, it should be a quick job to move the right one over to the correct switch terminal. Im thinking Id like to start with just a temperature indicator, to assist with the surfing. That is confusing. There are four buttons on the front: SET, run-program, up-arrow, down-arrow. This is an extra piece of wire for the European model of Gaggia Classic Pro (RI9480, 230V) with an energy-saving module, which turns off the machine after about 20 min if not used). But will there be an upper limit to prevent the boiler from going near 365F and blowing thermal. Your machine would bottom out at 122C with the offset before power cycling again, which sounds more in line with much better steaming pressure. 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 used to get this phenomenon with the original temperature control, but much less so, and I just used to run some water through the machine (using it to warm the shot glass and the portafilter especially if I hadnt had the machine warm up for very long) before pulling a shot. As for steam, the guide I wrote leaves the steam function completely untouched. Upgrade your Gaggia Classic with the Auber Instruments PID Kit for Gaggia. We have an earth leakage wiring system in our house, but in many countries, these are not standard. Hi Andrue. Again, as above, run this cable out the back, and leave it unterminated and longer than needed. Regulate the standby coffee water temperatureto within 1 (F or C) accuracy. 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. Hi Chris, I still have one question you may be able to answer. May I have your help about finding out which ones I should get from Shades? It is suitable for Gaggia Classic or other machines with a silver finish. Heres how to install a PID on the Gaggia Classic Pro. The Auber kit looks easy since I dont have time to build my own. 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). You wont need the heat sink, the GCs case does that job for you. I would be glad if you have any recommendations. Hey. Hi Miguel. Did you reverse any wires to the steam switch? One end of the wire should be a male disconnect connector, and the other end should be a spade connector. Its crazy. Started by Rocky47. No gross taste. Please see our Help Center's. For RI9403, please check KIT-GGX-EU. The only way to cut it is to unplug the machine. If you go for a PID, you need to use a thermocouple. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. If you can share a picture of it, or a link, I can add it to the article. I opted to follow my connections according to your picture, rather than that text. Hey Chris, The listing shows both M3 and M4 options, and I typed the first one when I wrote the article. Was hoping to actually just install one of these: https://www.ebay.com.au/itm/264849127538 Have you checked the temperature accuracy of your PID & Thermocouple? 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? When the pump runs, it vibrates the chassis and it will be a matter of time before it cuts through the wiring insulation.
