I have a 2012 and am wondering if you had success and if the wires are as described in the article. Tap the switched hot/load mains power: disconnect the lower left-hand (if facing the front of the machine) wire from the power switch. PID KIT for Gaggia Classic Pro 2018+ & Classic & Home, Pre-infusion. 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. Contact. Thanks Alex! Add to cart Buy Now. Main Feature. 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. 40A SSR Solid state relay included Hi Chris or anyone who may know the answer! 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. I was initially concerned about my wiring (and my GFI) but its reassuring to hear you have the same side effects. Cheers. The taste of a real Italian espresso everyday! This was such a great guide. 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. Please see the compatible model list below (Note 1 on the bottom). Thanks! Main Output: SSR: Open circuit: 4V, Closed Circuit: 24V40mA DC 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. This is sold on amazon Nikola. Thus, it will significantly improve the taste and consistency of your espresso. Im sorry about that, Eric. 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. Hello Chris, Its pretty straightforward. Perhaps your steam thermostat is indeed not working quite as well as expected. This would explain the constant switching on and off. Should this be cause for concern, maybe caused by an error in wiring the PID? Do not undertake this procedure if you are not comfortable or uncertain. 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? 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. The LED on the SSR is functioning but no current can be seen. If you want to defeat this feature, please add this optionto your order. I hesitate to identify wires by their color, as the wire colors in the Gaggia seem to vary from year to year and from region to region. You should now have two mains wires, two 12 volt wires, and the shielded thermocouple wire running out of the back of the Classic. 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. Shall I connect it to terminal 5 or 2 of the on-off switch? PID temperature control kit for Gaggia Classic Pro 2018+, Classic & Home. The Auber kit looks easy since I dont have time to build my own. You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. Once the machine has been set to 9 bars of pressure (see bottom of article), the next big improvement is the addition of a PID. Have you written an article regarding installing a Gaggiuino mod? The only way to cut it is to unplug the machine. Only needs 2 x AAA batteries. But Ive downloaded the wiring diagram for my machine. The grommet is used where the wires go through the chassis. But espresso is also among the more complicated ways to make coffee. Have you noticed any problem using REX-C100FK02 and RTD PT100? I then thought what if? and decided to change the mains wires to the opposite terminals. Thanks for your time. I have re-read the specifications for this controller. The thermocouple that I ordered fit into the threaded adapter without any modifications. 3-Connect the other cable to the terminal on the on off switch, which is on top of or below the Live cable. 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. Hard to say how long it took because I was doing other things as well (dimmer switch, boiler pressure gauge, boiler rebuild, etc.) 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. Its crazy. Hi Chris, I recently acquired a Gaggia Classic with an Auber PID controller installed. You need at least 20 amps. By the way there are three options as 12V, 24V and 85-250V DC. Circuit diagram of Gaggia Classic with the KIT-GG connection. Hi David. There are other resources online as well. 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 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! 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? I start to run the steam at about 130 in the heating cycle on my setup. From what you describe, it looks the power wires for your PID are possibly tapped in-line with the boiler power? 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. Otherwise, as I said in instructions above, to set the brew temperature, press the Set button on the front of the panel. Would you be able to post starting values for the PID kit please? Resetting or Taking out a Brewing Unit for Cleaning. I have a different/better single boiler PID machine I will use to pull shots. Silver case Black case TopBox with logo TopBox with gauge hole. Everything else (Auber and Mr Shades) includes an M4 thread on their pt100. I cant see why you couldnt. You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. The digital LED display module is available in red or white. I grabbed some screws from my parts bin, I took whatever I could find that was the same color as my filament, and that would fit the holes and hold reasonably well. Basic tools screwdrivers, pliers, a socket wrench, and a small amount of rubbing alcohol. I am glad this article helped. Do you think its going to blow my machine if I dont do correctly? If you used piggyback connectors, it should be a quick job to move the right one over to the correct switch terminal. Realized with your last comment you dont have the offset in place, my bad. Even with a perfect offset, you would also need to also take into account the temperature offset between the boiler and the portafilter. I decided that for me, its not worth worrying about. The Gaggia Classic is a very capable espresso machine that gets even better with a couple of improvements. Manual Machine Shop. The thermostat is a replacement, the original one burned around three years ago. Do you think this makes difference? Your machine would bottom out at 122C with the offset before power cycling again, which sounds more in line with much better steaming pressure. Im running into problems and I dont know if my REX-C100s starting values are the problem or if its my deviation with the wiring: Regardless of the temperature that i set on my PID, toggling the Gaggia on causes it to climb to 150-160C and then slowly decline to 118-125C, at which time it will heat up again. Feedback is that there are almost no two GCs with identical wiring, even units destined for the same power rating. I formatted the table, its very useful. Thanks heaps for the detailed instructions. I found that carefully pushing the boiler up gives better access to the thermostat, either from above, or by reaching up from below. But just like the kit I ordered, the threads on the thermocouple M8 according to the specifications are too big for the Gaggia. Likewise, you can use 22 awg for the connection between the PID and the SSR. Its no secret that the chassis of the Classic has extremely sharp edges. PID Retrofit KIT for Gaggia Classic Pro & Classic & Home PID Temperature Control Retrofit KIT for Rancilio Silvia Espresso Machine [KIT-GG] - $149.50 : Auber Instruments, Inc., Temperature control solutions for home and industry Home :: Coffee Machine Kits :: PID Retrofit KIT for Gaggia Classic Pro & Classic & Home Coffee Machine Kits Product 4/21 PID Kit for older plastic body Gaggia Classic. Does anyone else have this kit? Hi, thanks for the articely, it was great help to do the initial steps. When the temperature stabilizes to within 1 degree of the target temperature, the auto-tuning is complete. I ran the Autotuning function couple of times and I am always getting the following values for P, I and D parameters: P=620 , I=32, D=8. The label on REX-C100 says that it is produced by RKC, Japan but you never know for sure :-). Visit store Contact. . When I turn off, it goes back to zero. 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? Once warmed up, the recovery time is quick and the swing is fairly minimal. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. Your wiring looks right. Warning! Hope this helps. I am glad you got your setup working Murat. (PID Temperature Controller Meter Indicator, Jaybva Digital Universal Thermostat C and Fahrenhe F Display SSR and Alarm Output 40A Solid State Relay and Thermocouple Probe Heat Sink Included)? The operation is the same as the unmodified Gaggia machine. Are the steps here suitable for older machines like mine? 4.8. Plug in a mains-rated wire connected to a piggyback spade connector, and then plug the original neutral cable into the piggyback. 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. Does the PID generate enough heat to melt the Lego bricks? Its stimulated a lot of interesting discussion! If so, any idea how it can be achieved? Auber Instruments PID Kit for Gaggia Classic See More by Auber Instruments 4.8 6 Reviews CA$285.00 Earn 855 Reward Points worth $8.55! If the wiring in your machine is different from our installation guide, please contact us. Bliss. P, I, d, controlling period, digital filter coefficient, and more (for control theory experts only) 100% Upvoted. The pump can be stopped at any time by pressing the ">" key a second time. XMT720LCD . Supposed to be faster in detecting temperature changes and more accurate with the measurement. The Classics over-pressure valve (OPV) is set to 14 bars, which is a pressure better suited to the use of pressurized portafilters. Thanks for your reply: I think you are correct about the Gc being stuck in steam mode, but I never touched the steam switchs wires and reverting the top/bottom swap on the power switch didnt solve the issue. It will void your warranty, the possibility for making errors or breaking things during installation is too high, and the amount of time it takes would make it cost prohibitive. I am not sure exactly what you did when you moved the wires terminating on the bottom of the power switch. $149.99 . Hello, Also the PID starts with Auto Tuning disabled in my case, so had to be reset. Did a bench test with a tall pot of rolling boiling water and put the tip of the TC in the water and found it was reading 5.5 degrees low. I did not use a grommet. 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 . (For orders placed recently in 2022) If you placed the order as a guest, you cantry the, (For orders placed a while ago) Please log in and download the manual from your order history page. 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. On top of the original price tag, international shipping, taxes, duties and currency exchanges can make obtaining these kits time consuming and even more expensive. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. great article !!!! Because the PID runs on mains voltages, an enclosure is required. The steam temperature controlallows the boiler temperature to be held at a tighter range during frothing. This is the only concern left for me. Apologies for the long questions, thanks in advance! Contrary to the Gaggia circuit diagram, Black is live, White is neutral, a minor issue. that will make it where only one SSR is needed. Variants Coffee Only + Installation - No Coffee Only + Installation - Yes Coffee, Steam & Pre-infusion + Installation - No Coffee, Steam & Pre-infusion + Installation - Yes Quantity Free Shipping Parts You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. Leave as much of the thermal grease in place as possible. Be careful, the edges of the hole in the chassis are very sharp. Or buy a machine with a built-in PID. The steam mode drops to 102 before the power cycle kicks back in, with the valve open or closed. If you have never done this before, know that you are working with live household current, and this can kill you. 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. 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. Is it necessary to use a heat sink with the SSR installation? However I dont know if my unit is properly calibrated and/or has a proper offset. https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd. I would not try anything without checking first. Then I realized that EU models come not with a bistable rocker switch but a momentary one (so electricity flows only when you actively pushing the button). Check for wire that might have been too aggressively stripped, where some of the conductor might have also been cut away. Fortunately, no damage done, and you can easily revert your changes. . It should be the power/mains line that comes out of the main power switch, but before the boiler. Hi Brian. Ive set the Sn value to pt for the PT100. if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple. That is indeed not normal. Thanks again for all your support. Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. One bit of note and a request. Black case : Currently out of stock! Applications New - Gaggia Classic Pro/2019 PID kit - 1/32DIN single display. I have briefly thought about pre-infusion but the REX C-100 is not capable of this. Their kit is convenient, and is the way to go if someone doesnt feel ready to take on a 100% DIY project. Regulate the standby coffee water temperatureto within 1 (F or C) accuracy. It should be placed as close to the left-hand side of the Classic as possible. This gives the machine a whole new level of consistency, and gives you fine control over brew temperature. I think this is why using a separate SSR and controller is the only way to go. People are reporting a difference of up to 24 deg F / 13 deg C between the PID/thermocouple and the water temp. But, I still get loads of steam and spray before it settles down. Double sided tape will work. Hi Brian. Did you try with the SSR unit 40 DA or 40AA? Loosen the four bolts that hold down the boiler assembly. Unfortunately, no, you cant use the factory sensor. it does not matter if the bean is dark or light roast? 1 RELAY alarm: Normal open, capacity 250V/3A AC or 30V/3A DC To find the neutral inside the GC, you have to test using a multimeter or voltage meter. Measured everything with multimeter, then realized that C100 doesnt get main while machine is on based on the lights. Was hoping to actually just install one of these: https://www.ebay.com.au/itm/264849127538 I had no problem with my mod other than the stickers on the back of the PID were reversed, so the terminal markings were not correct. Approach 1: Follow my writeup, adapting it to your models peculiarities, and then set the PID temperature to your preferred steam temperature. Your email address will not be published. This is not a difficult mod. No extra button is needed to press for frothing. That being said, the original brew thermostat is supposed to be 107C, so could perhaps reach even higher temperatures? The PID unit did not turn on using the same terminal of your machine. Once these bolts are removed, the boiler can be moved around without having to disconnect any hoses or wires. My P value is quite a lot different than yours. 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. Hi Peter. Is it possible to do this with the GC factory temp sensor? The factory settings have been working well for me, aside from a ~5 degree C overshoot when it first reaches the target temperature. SKU: N/A Category: Accessories,Espresso Machines Tags: -GG-CLASSIC-PCB, $100-$300, $200-$300, 12annivexcluded, 13tierexcl, 300-600, Accessories, auber-instruments, gaggia, obalist, SA-GG-CLASSIC-P, SA-GG-CLASSIC-PCR, . I placed the SSR toward the left side of the back panel if facing the front of the machine. You can use the sensor reading on the PID display to know when to start steaming. That would be easy enough to verify with a multimeter, to see which thermostat is active in steam mode and which one is active in brew mode. PID TEMPERATURE CONTROLLER W/ 30 RAMP / SOAK, KILN $81.98. 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. This PID-SSR combination does away with the 12v connection, and uses three wires for the mains power and SSR, with one wire shared between mains and the SSR output. Regardless of which thermocouple you choose to use, you will also need to factor in an offset no matter what thermocouple you use, and this is really based on your tastes. I can actually taste the sweetness for the first time. Heat the shrink tubing. I am guessing that its caused by the current draw of the boiler heater. Ill be using a xmt7100 (modified) for two SRRs and also tweaked for 12v out for led mod any help would be appreciated. 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. I cant see how this wouldnt be a thermostat problem, unless you somehow wired the steam thermostat into the PID, but you would have gone way beyond this walkthrough to do that. 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? im trying to find out from shades why shades uses 2. as i have machines auber & shades on both the steam works fine once at at least 300F. Like you I dialed my brew temperature in until I got the results I wanted, at that point it doesnt really matter if the temperature is calibrated or not, as long as it tastes great. Hi, I just completed the DIY kit last night using your guide and it all went perfectly! A cheap multimeter is all you need. If you have the regular version (RI9380 120V, or 240V), you DO NOT need this wire. The Auber pretends to add a couple of things, but functionally, they're very much the same. There are four buttons on the front: SET, run-program, up-arrow, down-arrow. Remove the cover assembly and filler funnel by unscrewing the two small screws at the rear of the top. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. It has been working flawless for the most part, but seen a few issues that havent seen before. Try powering the PID directly from mains power, with just the thermocouple connected (disconnect the SSR). Is this just a matter of adjusting the offset of the PID? 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. PID Kit for older plastic body Gaggia Classic. [KIT-GG] Auber Instruments, Temperature control solutions for. 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 would not make it without you. Autotuning had resulted in shot instability up to 10 degrees during a shot probably because conditions during standby and during brewing are very different than each other. I have not changed any of the P, I or D settings on my controller. Hi Joe. Like NEW Gaggia Classic Espresso w/ Grinder and Base - - 6758821731. $326.00. 19K Items sold. 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). Indeed, not an option. if i understood not adding a steam will give better steam? The enclosures purpose is first to protect you from the mains current, and second, to make it easier to attach the PID to the Gaggia. I hope you enjoy your upgraded GC as much as I do mine! MY GC does the same thing, the pump tone changes when the boiler is heating. Useful Video. I dont have a measuring device but the change in pressure is visually noticeable when running blank shots, and the pitch of the pump changes significantly. This is a Used Black Appliances for Sale in Fairlawn OH posted on Oodle Classifieds. BREWING UNIT RE-SETTING AND CLEANING. Is 103 degree Celsius the best target temperature fit the PID? We ship every business day from our two warehouses located in Milton, Ontario and Calgary, Alberta. Leave this cable longer than needed for now, it will be trimmed and terminated later. In the text it says M4, but on the picture, it highlights to use the M3. Its actually reading too high.. 98 deg against 92deg measured by both my oven thermometers. Thank you very much if you find the time to answer me . Instruction Manual for PID controller kit - Picr. Thanks. Thanks for the PID info. I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. Do I need to make any adjustments to your procedure to make the PID handle the steam only (not caring about the group head)? sv4mzu 20, 2022 8:05 am. Both shades and auber use the alarm 1 & 2 though with different PIDs for steam with upper limit & lower limit. You should see no or very low voltage between neutral and ground, and you should see household voltage between the hot/load and ground. I am thinking to upgrade my classic pro more compact version with below controller. This is probably the most difficult part of the installation. I havent lowered brew pressure to 9 Bars yet so perhaps changing that would level out my pump pressures? Box color. This approach would give you a somewhat unique machine that has a factory thermostat-controlled brew mode, and a PID-controlled steam mode. Adding pre-infusion would require either a different and significantly more sophisticated PID, or integration with something like a microcontroller. 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. 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. This steam blipping is a fairly common practice that people use to avoid boiler heater cycling, its just another way to do temperature surfing. I have a 2013 Gaggia Classic. Hi Nish. 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. CONCLUSION! 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. Chris, i read some comments here about steam. Gaggia Classic Seamless PID Upgrade. Before replacing the thermostat, maybe check whether your PID and thermocouple are calibrated, before committing to buying more parts. 5. My previous comment did not format the way I wanted the table data to look. I like the quality of the shots, and temperature consistency is more important to me than pressure consistency. If you purchased the kit from our website, you can download the manual zip file from our website by one of the following methods: Note: 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. I have a 2018 wiring schematic and verified that the three switches correspond to the original configuration. This works well with a PID for light & medium roasts. See here for details. It also means that you can only see the temperature and access the PID buttons from the top. I was able to create one using Lego bricks sitting around in the basement. 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. Without offset the range is between 109-159, still too low. It is the perfect place. Close. Previous topic - Next topic. The way I wired the PID leaves it powered on as long as the main power switch is on. 1. Some shops are quoting $80.00 for the PID enclosure + lid. If you go for a PID, you need to use a thermocouple. $136.08. Hi Jeff. UNBLOCKING. One end of the wire should be a male disconnect connector, and the other end should be a spade connector. Here are a couple of examples: Hi Chris, Gaggia Classic Pro (released in 2018/2019) models, including the, PID temperature control kit for PID Retrofit KIT for Gaggia Classic & Home, KIT-GG, How to Download Manuals for Login-Required Kits, USB LCD PID Temp Controller with Timer, Ramp Soak Optional RS485, Silicone Braided Cable for PT100-L Series Probe, 12 ft, Water-Resistant 3-Pin Connector, Rear Mount, Round Flange Socket, (For orders placed recently in 2022) If you placed the order as a guest, you cantry the, (For orders placed a while ago) Please log in and download the manual from your order history page. A copy of the digital manuals, which includes a detailed installation guide, an operation manual, and supplementary documents. The default target temperature on the PID will almost certainly not be correct. I am now waiting for my PID unit and thermocouple with M4 head to arrive this week. Im so thankful for this.
