Hi, thanks for the articely, it was great help to do the initial steps. Thread the thermocouple wire through to the back of the machine, and out the same slot as was used for the other wires. Nevertheless, it will take some time to get it and make a change of the temperature sensor. I am guessing that its caused by the current draw of the boiler heater. In a properly wired North American outlet, the neutral wire is white, and the hot/load wire is black (ground is green). Select the preferred temperature unit so that all parameters are pre-set properly for you. I was like WTF. Does this mean that I have made the connection properly? How do I ensure that Im tapping the neutral mains? Thank you. Awesome PID installation guide! Im sorry about that, Eric. Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) The Classics over-pressure valve (OPV) is set to 14 bars, which is a pressure better suited to the use of pressurized portafilters. the PWM needs a new wire to the where the pump wire was disconnected. I would like to use it for steaming ONLY. Hi Tom. Hi Eddie. Like NEW Gaggia Classic Espresso w/ Grinder and Base - - 6758821731. I'd like to increase the brew temp a couple of degrees but have no idea how to do this. The cup warmer does seem a bit hotter than before (but have only used twice since installing, so Ill have to pay attention). (Optional) Add-on Item. If you had to recommend a single display PID, which one would you steer me to? 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. Hi Miguel. Good idea Chris. () . There are other resources online as well. i set an upper an lower limit on alarms. You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. Allow easy adjustment on the coffee water temperature. Watching the steam temp with the PID is interesting (I know it has no effect on it, but it is cool to see how it reacts now) and it is definitely best practice to steam while its on its way up in temp, once it hits the set point it comes down for a while (mine settled around 130 before it started back up). European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Is it necessary to use a heat sink with the SSR installation? Thank you for making it. Do you think this makes a difference? Circuit diagram of Gaggia Classic with the KIT-GG connection. I know what I will be trying tomorrow , Hi, Wear a glove when reaching in from below, otherwise bloodletting is likely. on orders over $49. Hi Kraken. I formatted the table, its very useful. For the melted connector plastic, thats a sign of either a wire or a connector that is carrying too much current for its rating, or most likely, a connection between the wire and connector that is not as solid as it should be. I am not sure exactly what you did when you moved the wires terminating on the bottom of the power switch. Also some pids come with a built in relay. The best part is I am only in about $40 on my kit compared to around $150 for the pre made kits. The black box has a durable powder coating. But espresso is also among the more complicated ways to make coffee. report. And this is the thermometer out the back. Have had the parts sitting around for months and no time to install! I have installed the supply cable for PID unit using piggyback spade connectors. Thermocouple: J,S,K,E,Wre3 ~ Wre25 Replies: 2 Views: 1,615. The C100 is probably made by dozens of different manufacturers. The best simple info I found was a table that summarized what INCREASING each of the PID parameters would do: which I used to adjust my settings. Zip ties, heat shrink tubing, thermal paste, double sided tape, and a bolt and nut to attach the SSR are also required. Thanks for putting it together, this has helped me a lot in figuring out most of my doubts with a PID project for a Gaggia. Monday - Friday: 10am - 4:30pm. 6 Reviews (6) $326.00. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. Hi Miguel. Display: Dual display for Fahrenheit(F) and Celsius(C) Shall I change the P,I and D parameters manually and what is your suggestion to start with? How to install a PID on a Gaggia Classic Pro - DIY, cheap and good looking! The countdown extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). Leave the Classic powered on for at least 15 minutes. Do you think that REX-C100FK02-V*EN (designed for K-type thermocouple) is compatible with RTD (PT100) and is not going to create long-term problems with the machine/setup? Thx, Hi Chris, I dont own a multimeter. The kit installation is fully reversible. It is suitable for Gaggia Classic or other machines with a silver finish. Then use the cursor keys to select the digits to increase and decrease. Do you have any diagram of the wiringi cant understand how to switch on the steam circuit so the second SSR would not try to heat the boiler in parallel. Unfortunately, I didnt measure any temperatures for the un-modified machine. 1 RELAY alarm: Normal open, capacity 250V/3A AC or 30V/3A DC Ive set the Sn value to pt for the PT100. 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! 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. Rancilio SilviaPID. Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. You can use the same 18 gauge wire between the heating element and the SSR. One thing I would really recommend when anyone installs a PID system into the Gaggia Classic is to install a rubber grommet where the cables exit the machine. Hi Chris, Chris has done a great job on this write up and its easy to follow. 3. https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_asin_image_o05_s00?ie=UTF8&psc=1, BOX 7. You can use the sensor reading on the PID display to know when to start steaming. QB-T7200 48*24mm Programmable Digital PID Temperature Controller with Built-in 5A Solid State Relay XMT7100 AC/DC85~260V. Hi Gene. I do not want to risk damaging my machine because of this. I have few questions for you about this setup. Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! As for your PID always remaining on, it looks like you wired it to the unswitched mains, instead of the switched power. Silver case Black case TopBox with logo TopBox with gauge hole. I would not try anything without checking first. I have a similar model, C100-Fk02-V*AN. Ill be using a xmt7100 (modified) for two SRRs and also tweaked for 12v out for led mod any help would be appreciated. This prevents the high-pressure water from contacting the dry coffee powder which can create afast flow channel, ruiningthe brewing process. Not really preinfusion, just an excellent way to crack the puck before your shot starts. Hi Jeff. Sign up for emails. The steam mode has its own thermostat, which is very similar to the brew thermostat that the PID replaced, except that its temperature range is more or less as you described. You can search on Reddit, a few people have made these modifications. Is this just a matter of adjusting the offset of the PID? Steam will still be controlled by the steam thermostat. I double checked all the wiring (inside and outside of the chassis) and eventually came to the conclusion that I had a faulty PID. I would not make it without you. Thanks for the great guide. 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. Possibly not the optimal position but was really easy to install and I knew Id only be getting a relative indicative temperature anyway. This is not a difficult mod. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. Thanks. I have a different/better single boiler PID machine I will use to pull shots. Loosen the four bolts that hold down the boiler assembly. Either way, you are looking at a lot more complexity and cost. The PID kit you described should work, but like the C-100 kit the I used, the included thermocouple wont fit in the Gaggia Classic. I strongly suggest checking which switch terminal switches the mains. Hi Justin. I was initially concerned about my wiring (and my GFI) but its reassuring to hear you have the same side effects. I placed the SSR toward the left side of the back panel if facing the front of the machine. Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. After the kit is installed, the standby brew watertemperaturecan be controlled to within 1 (F or C) accuracy. But, I still get loads of steam and spray before it settles down. Hey Chris, Apologies for the long questions, thanks in advance! The fun of the PID is not just the great stability, but the ability to fine tune the brew temperature to your taste! $149.99 . GAGGIA Classic 2021 550.00 , : PID KIT 129.17 , Top Box 35.00, OPV KIT . You should be done! Thank you again for taking the time to write up such a great guide. Please contact us if any questions. The pump can be stopped at any time by pressing the ">" key a second time. Supposed to be faster in detecting temperature changes and more accurate with the measurement. 5. I have re-read the specifications for this controller. Hi Brian. The idea of the chassis becoming live doesnt bear thinking about. Thanks in advance for any reply! Should I get the Auber Instruments PID kit w/ pre-infusion or w/ steam control? 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. I had no issues with the K type thermocouple. 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. If its closed it takes longer for temperatures to drop, but still goes to 102 before the it power cycles. Always work with the Classic unplugged. Run-program does a 1s pre-infuse followed by about 1s pause, then 30s pump on. When the temperature stabilizes to within 1 degree of the target temperature, the auto-tuning is complete. I am not surprised that the steam kit made little difference. You would probably blow the fuse in this controller/SSR within seconds. Shades and Auber Instruments. Connect one meter probe to ground (the GC chassis should always be grounded, otherwise connect to the green wire coming from the power socket at the back). Double sided tape will work. There is definitely something weird going on. Use the other probe to check the other two wires coming from the power socket. I installed an Auber PID on my Gaggia Classic earlier this year. Whole Latte Love has a new video about preinfusion on the classic. I have found this PID kit here on Ali express and I think its the same one you fitted can you please tell me if this one is good to go, they got a 3 piece option and a 4 piece option so dont know which, I think the 4 piece option is because it includes a heat sink that you dont mention, so I assume I wont be needing it, can you please advise. 0. (To be certain, the M4 is the correct one). My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). One end of the wire should be a male disconnect connector, and the other end should be a spade connector. Basically, instead of running the pump for a few seconds and then shutting it off (which dumps your pressure courtesy of the solenoid valve) you open the steam valve about 1/4 to half way, hit the brew switch and then slowly close the steam valve (about 5 seconds or so). Cheers. Pull the steam wand up and out of the Classic, and set it aside. 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. I am glad you got your setup working Murat. I then thought what if? and decided to change the mains wires to the opposite terminals. 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. That is confusing. The boiler had been installed in such a way that it had pinched/nearly severed the upstream wire on the brew light. So I would say yes, you should use a heat sink, but the Gaggia body conveniently provides you with that function. hide. If you really want these features, its probably time to think about upgrading your machine. Jun 25, 2014 - Auber Instruments, Inc. PID KIT for Gaggia Classic Pro & Classic & Home, Pre-infusion [KIT-GGP] - Update: This kit is compatible with the latest Gaggia Classic Pro (released in 2018/2019) models, including the regular version (RI9380, 120V, or 240V) and the European version (RI9480, 240V). QB-T7100 48*24mm Programmable Digital PID Temperature Controller AC/DC 85-250V To do this, loosen the nut connecting the steam wand to the steam control assembly. it is basically removing the main pump wire and re routing back to the PWM out. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. Its threaded on, and should not be very tight. Note that my mod is to a Gaggia Classic, not a Gaggia Classic Pro. Auber Instruments PID Kit for Gaggia Classic. Unlike the 7200 model, this one does not have SSR inside. I dont want to void my warranty. The most I can say is these work for me, and are probably not optimum. 3 months later, Ive finally set up the PID and honestly, its a gamechanger! The factory settings have been working well for me, aside from a ~5 degree C overshoot when it first reaches the target temperature. 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? This kit has a pre-infusion timer. But I wondered if anyone has had the same problem and already found the answer! I started with 103, and bumped it up to 105. One question, Ever thought about adding a pre infusion feature? The only way to cut it is to unplug the machine. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. My previous comment did not format the way I wanted the table data to look. I havent lowered brew pressure to 9 Bars yet so perhaps changing that would level out my pump pressures? BREWING UNIT RE-SETTING AND CLEANING. You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. My question is where did you place the SSR, is it near the water spout, right side or in the back if you are facing the front of the machine? Perhaps you are refering to the video by Damian Witonski. It is the perfect place. 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. Can anyone advise on the PT100 sensor setup? My Gaggia Classic uses 18 awg wire for every connection inside. I would re-crimp any connections that look suspicious. Chris, do you recall what size flat head screw was used on the 3d printed box for the REX-100? The on/off temperature can be adjusted by the user. $285.00. The same complexity applies to pressure control. it does not matter if the bean is dark or light roast? Plug in a mains-rated wire connected to a piggyback spade connector, and then plug the original neutral cable into the piggyback. 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. Thats an awesome enclosure. i ordered K type and PT100 both for M4. Tap the switched hot/load mains power: disconnect the lower left-hand (if facing the front of the machine) wire from the power switch. Hello, I acquired and prepared all cables and SSR unit thanks to your well prepared title above. Based on several comments, the wiring varies between units, even though they are the same model. 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. Thats what Auber and Shades use, although they make their own. If the wiring in your machine is different from our installation guide, please contact us. The thermostat is a replacement, the original one burned around three years ago. 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. When set up on my bench it tucks away nicely in behind out of sight and only needs to come out when in use. Stay connected. Bliss. different wiring though. Did you try it? GRAN GAGGIA PRIMING. 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 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. I am glad this article helped. Great guide. Auber Instruments PID Kit for Gaggia Classic. Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm. Hi Jun, glad you found this helpful. And anything is going to be a huge improvement over the thermostat that the PID replaces. Main Feature. Hi Chris, Indeed, not an option. 2. Other than that mine was a fairly straightforward procedure with no trouble at all. Net Weight: about 150g The 12 volt wires from the SSR connect to terminals 4 and 5. Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. The thermocouple that I ordered fit into the threaded adapter without any modifications. Between SSR and PID I was planning on using 22 awg wire given its a lower power requirement. We bring fresh high-quality coffee to the masses. Hard to say how long it took because I was doing other things as well (dimmer switch, boiler pressure gauge, boiler rebuild, etc.) Make sure that all the new and repositioned wires are cleanly routed away from the boiler and pump and any uninsulated connectors. And once you start considering adding in a power supply, you might as well go for a PID. Set the cover and screws aside. Hey. Heat the shrink tubing. 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. This prompted me to look for alternate solutions. Specifications : That is indeed not normal. Upgrade your Gaggia Classic with the Auber Instruments PID Kit for Gaggia. Auber Instruments PID Kit for Gaggia Classic. So you could measure water temp at the group head at 180 deg F with the PID set to 204 deg F. There is some interesting information here: https://coffeeforums.co.uk/topic/53319-what-temp-offset-are-you-using-with-your-pid/.
