Contact. To set the target temperature, press the 'Set' button on the front of the panel. Ive attached an album with my wiring below; Ive literally had an engineer look at it and The Gaggia is 100% at its original state except for the power taps on the neutral at the plug, the live on the brew switch, and the thermocouple to SSR wiring: https://imgur.com/a/rc4xtfz. Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! Due to your kind and quick advice, I could order SSR40DA. 5: The PID controller in this kit is NOT SYL-1512A. I do not suggest autotuning for this device because there is a huge improvement in temperature stability if you do the tuning by yourself. 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). In the text it says M4, but on the picture, it highlights to use the M3. When I turn off, it goes back to zero. 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. Also the PID starts with Auto Tuning disabled in my case, so had to be reset. Hi Jimmy. Warning! Are the steps here suitable for older machines like mine? XMT720LCD . Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. This steam blipping is a fairly common practice that people use to avoid boiler heater cycling, its just another way to do temperature surfing. Hi Jeff. 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. Tighten one end of your connector down to one of the solid state relays AC (~) terminals and plug the other end into one of the disconnected thermostat wires. Did I miss any other kits? I should pointed out that the temperature ranges I was referring to were with the -8C offset on the PID. The boiler had been installed in such a way that it had pinched/nearly severed the upstream wire on the brew light. 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. $149.99 . 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? Close the PID enclosure, and attach it to the side of the Classic. I placed the SSR toward the left side of the back panel if facing the front of the machine. it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. This kit doesn't control the steam temperature nor has the pre-infusion function. Chris has done a great job on this write up and its easy to follow. Hi David. 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. Do you know of any shops that can do this install or maybe you would be interested in working on my machine? 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. 19K Items sold. Regarding the M4 screw/ thermocouple, is it possible to amend the picture? Read More. The silver box is coated with clear anodized aluminum with a brush-finished stainless steel front panel. The most I can say is these work for me, and are probably not optimum. Does anybody have a Shades of Coffee pdf for the brew and steam setup on the gaggia classic, mines a 1998 classic coffee model, it would be much appreciated. You should be done! 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. This is the only concern left for me. QB-T7100 48*24mm Programmable Digital PID Temperature Controller AC/DC 85-250V 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. 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. Which one shall we buy? No extra button is needed to press for frothing. Started by Rocky47. The countdown extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). The taste of a real Italian espresso everyday! The default target temperature on the PID will almost certainly not be correct. 2: The add-on item option "extra wire defeating auto-off timer" is for the Gaggia Classic Pro European model (RI9480, 240V), which has the auto-turn-off timer feature. that will make it where only one SSR is needed. Then use the left/right buttons to select the digits to increase and decrease, and the up/down buttons to change the digits. Then the PID will only switch on when the boiler temperature drops below the target temperature. Mains is house current. However, when I flip the gaggia power switch to off, the PID LCD screen remains illuminated. The pre-infusion timer can also be used as a countdown shot timer. You could simulate pre infusion by briefly running the pump. If you want to defeat that auto-power-off feature, please add this piece of wire to your order. Did you try it? This prevents the high-pressure water from contacting the dry coffee powder which can create afast flow channel, ruiningthe brewing process. Please see our Help Center's. You are right, its an M4 thread, not M3. I hope you enjoy your upgraded GC as much as I do mine! GAGGIA Classic 2021 550.00 , : PID KIT 129.17 , Top Box 35.00, OPV KIT .

My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). These connectors are hard to reach, and are on very tight. But I would definitely read the instructions that come with whatever you receive! Hi Nish. It should be the power/mains line that comes out of the main power switch, but before the boiler. This feature allows you to operate the brew pump manually, with the timer as a reference. Thanks, David. I strongly suggest checking which switch terminal switches the mains. Our provided installation manual is based on the Gaggia Classic 2016 (model# RI9403/11). Hi Jeff. We ship every business day from our two warehouses located in Milton, Ontario and Calgary, Alberta. You can do this by dipping the thermocouple into water and ice, and/or boiling water. Hi Jun, and thanks for the update. But espresso is also among the more complicated ways to make coffee. My problem is that since installing the mod, my machine gets way too hot and boils. There is no 12v anywhere in the GCP, its all mains power inside. This is the setup that I have assembled two days ago. Glad you got that sorted out. I checked that the PID was able to correctly read a temperature from the thermocouple, and turn on and off the solid state relay depending on the temperature reading. Is there a way to tap into +/- 12Volts inside the GCP? It also means that you can only see the temperature and access the PID buttons from the top. 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/. 100% Upvoted. At the amperages required to control the boiler heating element, you need an SSR that has enough mass and exposed metal to be able to attach it to a heat sink. https://www.vertex-qis.co.uk/Manuals/PT100_con.pdf. Auber Forum. The C100 steps down mains voltage to 12v to power the SSR. See our 325 reviews on.

Please be sensible and install a grommet anyway! I bought the PiD from Amazon referenced in a comment above and its working fine. I know wiring might be different colours but is everything in the same place? The thermostat is a replacement, the original one burned around three years ago. I did that exercise before installing the PID, behavior should be identical as that time. Did you have any problems or stumbled upon anything unexpected? Do the same with the other connector wire. Thats an awesome enclosure. I used the same controller ( XMT 7100 ) which Mr Shades is selling. The thermocouple that I ordered fit into the threaded adapter without any modifications. I agree the ability to know exactly where the steam cycle is at is a nice convenience. So there is more or less no concern about PID heat and the PID enclosure. Is it necessary to use a heat sink with the SSR installation? 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? My plan is to install the Rex C100 first using your instructions. It doesnt matter which mains terminal is connected to hot and which one is connected to neutral. PID Kit for older plastic body Gaggia Classic. different wiring though. The black box has a durable powder coating. 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. 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. Maybe this will help? That is indeed not normal. (for a reasonable fee of course). This works well with a PID for light & medium roasts. i ordered K type and PT100 both for M4. There are four buttons on the front: SET, run-program, up-arrow, down-arrow. This PID controller kit has all the features of our other listing titled "PID temperature control kit for PID Retrofit KIT for Gaggia Classic & Home, KIT-GG", with the addition of pre-infusion and steam temperature control. Thanks for the quick reply. Be careful, the edges of the hole in the chassis are very sharp. This product was added to our catalog on Tuesday 26 June, 2007. Its pretty straightforward. I also checked to ensure that the physical steam switch is functioning correctly and the circuit is broken when it is off. I am flattered, but will have to pass. 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. When I started steaming at that point thermostat never shut down the boiler because temperature did not reach to limit of thermostat. Hi Anton. Have you got any ideas what might be going on? Thanks in advance! https://www.thingiverse.com/thing:4243840. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. Since installing the modification, I get a huge amount of steam and spray coming out of the portafilter when I first operate the pump so much so, that it sprays all over the worktop around the machine! PID Kit for older plastic body Gaggia Classic. GAGGIA CLASSIC - MODDED. Where did you place the SSR? https://wiki.wholelattelove.com/File:GAGGIA_CLASSIC_2019_Wiring_Schematic.pdf The installation is completely reversible if you ever want to sell the machine or send it to service. Thanks again for the write up, Ill be playing around with temperature for the next week! For questions, please contact us. I want to get a PID for my GC. 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. I then thought what if? and decided to change the mains wires to the opposite terminals. But that also seems fiddly. 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. Thanks. Thanks for your time. Select Your Mounting option. I agree, the PID is a gamechanger. From what I gather, youre located in the lower mainland (B.C.)? For RI9403, please check KIT-GGX-EU. it is basically removing the main pump wire and re routing back to the PWM out. Hi Brian. I will purchase the PID kit with thermocouple and SSR from aliexpress and buy these rest small items from Mr. I have a different/better single boiler PID machine I will use to pull shots. have you had any issues with the k type or have heard of this? I would not make it without you. I cant see why you couldnt. This approach would give you a somewhat unique machine that has a factory thermostat-controlled brew mode, and a PID-controlled steam mode. Depending on the draw of the display (I saw 50mA somewhere), you could also try running it off a battery. Users can also bypass the timer to use the switch on the machine for manually controlling the brewing process. The fun of the PID is not just the great stability, but the ability to fine tune the brew temperature to your taste! Allow easy adjustment on the coffee water temperature. Hi Nitzan. If the wiring in your machine is different from our installation guide, please contact us. You said here that the to get an M3 thread for the boiler. Hi David. Because the wiring connections can vary between manufacturers, you should bench-test your setup before final assembly. The PID switches the power to the boiler heating element on and off a lot more frequently than the original mechanical thermostat. and its definately better than Auber which is NOT preinfustion by kicking off solenoid. If so, any idea how it can be achieved? I would be glad if you have any recommendations. Unfortunately, I didnt measure any temperatures for the un-modified machine.

Run this wire along the rest of the existing cables and out the back of the Classic, through one of the vent slots. The preinfusion thing is a bit ridiculous, it just turns your pump on, off and on again. I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. Auto-tuning PID cooling/heating control Measured everything with multimeter, then realized that C100 doesnt get main while machine is on based on the lights. Which Auber PID for Gaggia Classic? This does mean that you can only fill the water tank by pulling it out. Here are some pictures of the Lego enclosure: https://www.reddit.com/r/espresso/comments/owpfe7/i_made_a_lego_enclosure_for_rex_c100_pid/. I bought the same parts as you have reccomended in the article but have run into the issue that the thermocouple is too large to fit into the adapter (theyre approx the same OD). Stock situation: Silver case : Last one or two!!! The PID itself draws very little current, so something like 18 gauge lamp cord would work. 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. Does this pid control both the group head water and steam wand? I have re-read the specifications for this controller. 103 or 105 is good. https://www.auberins.com. Please see the compatible model list below (Note 1 on the bottom). Do not undertake this procedure if you are not comfortable or uncertain. Cross referencing with the with the manual confirmed that the stickers had been reversed. BREWING UNIT RE-SETTING AND CLEANING. 6 Reviews (6) $326.00. The PID will show the temperature, and be somewhat confused by its inability to reach its setpoint, however the PID is bypassed in the same way when the GCP is in steam mode. and I didnt work straight through, but I would say the PID took me about 2 hours, not counting the down time due to the crossed power wires. Wear a glove when reaching in from below, otherwise bloodletting is likely. Should I get the Auber Instruments PID kit w/ pre-infusion or w/ steam control? It has been working flawless for the most part, but seen a few issues that havent seen before. Also really awesome write up. 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). Im sorry about that, Eric. Because the PID runs on mains voltages, an enclosure is required. if i understood not adding a steam will give better steam? 3.
