Chris thank you so much. Plug in a mains-rated cable connected to a piggyback spade connector, and then plug the original switched mains cable into the piggyback. The only other thing I can think of is the relay. 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? You could definitely drill out the adapter a bit to get the thermocouple to fit. If in doubt, sit it out, and get some help. For me I start steaming when the boiler temperature reads 130 degrees C. So for others who are contemplating going for the extra effort of installing the steam PID, know that the return on investment of doing this is questionable, if not net negative. Before replacing the thermostat, maybe check whether your PID and thermocouple are calibrated, before committing to buying more parts. PID KIT for Gaggia Classic Pro 2018+ & Classic & Home, Pre-infusion $209.99. Please see the compatible model list below (Note 1 on the bottom). You can search on Reddit, a few people have made these modifications. 0. I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. ). Regarding the M4 screw/ thermocouple, is it possible to amend the picture? Do you observe the same temperature ranges? Warning! If youre following a recipe that calls for a specific water temperature, then it would be easier to do this with an offset at the PID. The connector is on the back of the machine, where mains power is tapped with a piggyback connector and goes to the PID. (To be certain, the M4 is the correct one). Auber Instruments PID Kit for Gaggia Classic. Thermocouple: J,S,K,E,Wre3 ~ Wre25 Like NEW Gaggia Classic Espresso w/ Grinder and Base - - 6758821731. For RI9403, please check KIT-GGX-EU. Pull the steam wand up and out of the Classic, and set it aside. Individually PID control parameters The way I wired the PID leaves it powered on as long as the main power switch is on. 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. Its actually reading too high.. 98 deg against 92deg measured by both my oven thermometers. Do you think its going to blow my machine if I dont do correctly? Display: Dual display for Fahrenheit(F) and Celsius(C) I am not surprised that the steam kit made little difference. The kit installation is fully reversible. Then use the left/right buttons to select the digits to increase and decrease, and the up/down buttons to change the digits. After all this, I found that with the PID setpoint set at 94C, the brew temperature would rise to 94.5 and fall to 92.5 minimum. Have you noticed any problem using REX-C100FK02 and RTD PT100? Mounting Dimension: DIN: 1/16 (48mmX48mmX80mm) 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. This is really a DIY project. Im in North America btw. I installed the PID so that there are no permanent modifications to the machine, and the Gaggia can be returned to factory condition at any time. Shop. 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. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. Hi Peter. The black box has a durable powder coating. as a cheap indicator to assist with surfing. 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. The Rex c-100 reads in Celsius only, would I be able to substitute this kit with: The factory settings have been working well for me, aside from a ~5 degree C overshoot when it first reaches the target temperature. The most I can say is these work for me, and are probably not optimum. Thanks. The PID gives you consistency. (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. With a PID controller added to the heater control circuit, brew water temperature can be controlled to within 1 accuracy. I used lamp cord for this. that will make it where only one SSR is needed. if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple. (The Gaggia machine is not included in this listing). 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. http://facebook.com/HKCoffeeHome EspressoGaggia Classic !Gaggia Classic can give a good espresso shot . Thanks for the great guide. Hi Paul. Hello Chris, European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Is this just a matter of adjusting the offset of the PID? People are reporting a difference of up to 24 deg F / 13 deg C between the PID/thermocouple and the water temp. The default target temperature on the PID will almost certainly not be correct. New - Gaggia Classic Pro/2019 PID kit - 1/32DIN single display. $285.00. Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. it is basically removing the main pump wire and re routing back to the PWM out. Hi Anton. Adding pre-infusion would require either a different and significantly more sophisticated PID, or integration with something like a microcontroller. 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. Thanks in advance. It will depend on the beans you use, and your palate. Hi Miguel. Hello Chris, Hey. 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. But I wondered if anyone has had the same problem and already found the answer! I was initially concerned about my wiring (and my GFI) but its reassuring to hear you have the same side effects. . 100% Positive Feedback. 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. Most likely they will have the same connector types as the REX-C100, but its always possible that you will need different connectors depending on what you end up ordering. Its no secret that the chassis of the Classic has extremely sharp edges. When the steam switch is on, the PID stays on but because the boiler temperature in steam mode is much higher than the brew temperature of the PID, the PID provides no power to the SSR and heating element. 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. Thanks in advance, this was a huge help! I have read reports of measurements of up to 8 degrees C lower at the portafilter. Allow easy adjustment on the coffee water temperature. In mine, correct terminal was crosswise of yours. You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. Neutral is the return path for the hot or load wire. It doesnt matter which mains terminal is connected to hot and which one is connected to neutral. Remove the thermostat. Its getting very hot indeed so turned it off. Also some pids come with a built in relay. Its crazy. Two different colors of the controller box are offered, silver and black. Nevertheless, I will take a look and see what values my controller is set to. This process involves working with potentially lethal mains-level voltages. Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. 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. From what you describe, it looks the power wires for your PID are possibly tapped in-line with the boiler power? Main Output: SSR: Open circuit: 4V, Closed Circuit: 24V40mA DC Other than that mine was a fairly straightforward procedure with no trouble at all. A cheap multimeter is all you need. The PID unit did not turn on using the same terminal of your machine. 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. Each segmentcan be set by the user with 0.1 seconds resolution. Submit. 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). Warranty: 6-month limited warranty with a 30-day money-back guarantee is offered. Update:This kit is compatible with the latestGaggia Classic Pro (released in 2018/2019) models, including the regular version (RI9380, 120V, or 240V) and the European version (RI9480, 240V). If you want to defeat this feature, please add this optionto your order. In the text it says M4, but on the picture, it highlights to use the M3. Is this a typo on your part or a mistake on their part? And once you start considering adding in a power supply, you might as well go for a PID. Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. It really pays off to assume nothing, and test everything. Take your time, think it through, and be patient. Gaggia Classic Coffee Machine Modelo 3D TurboSquid 1036412. I also think that you may have less difficulty reaching the thermostat, the 2019+ models have a lot less room to spare inside. One question, Ever thought about adding a pre infusion feature? Which Auber PID for Gaggia Classic? Thanks! Monitor and display the boiler temperature precisely. $375.00. Once these bolts are removed, the boiler can be moved around without having to disconnect any hoses or wires. 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. Perhaps Ill use a spare Arduino or FPGA to PWM the boiler while brewing as someone else was saying. 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. Set the cover and screws aside. This would explain the constant switching on and off. You want to connect the PIDs mains power terminal to the side of the Gaggia power switch that cuts out power when the machine is off. The C-100 will fit in vertically, with the screen facing up. Monday - Friday: 10am - 4:30pm. Hello, there is another model without SSR built in with name 7100 instead of 7200. Did you try with the SSR unit 40 DA or 40AA? on orders over $49. Its not a sensor, it doesnt send any information, it just switches on an off, at setpoints that you cant adjust. The YouTube video from wll about replacing the boiler made the whole thing very easy. (for a reasonable fee of course). I double checked all the wiring (inside and outside of the chassis) and eventually came to the conclusion that I had a faulty PID. A copy of the digital manuals, which includes a detailed installation guide, an operation manual, and supplementary documents. This gives the machine a whole new level of consistency, and gives you fine control over brew temperature. Spent some time playing with temps and pulling a lot of shots to dial it in and am very happy with the results. You wont need the heat sink, the GCs case does that job for you. Its one more thing to plug in, but the upside is that it would be electrically isolated from the Gaggia. Thank you again for taking the time to write up such a great guide. Resetting or Taking out a Brewing Unit for Cleaning. Unblocking Solenoid Valve-Classic and Baby. Black case : Currently out of stock! No gross taste. . If your connection is down to just a few strands, that will generate heat. I found that carefully pushing the boiler up gives better access to the thermostat, either from above, or by reaching up from below. 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. As for steam, the guide I wrote leaves the steam function completely untouched. Fast, Free Shipping. It did take a few rounds to get it right, but it was successfully installed and functioning for a few months. I think one of either is the one which Shades of Coffee is using. Is there a way to tap into +/- 12Volts inside the GCP? It should be the power/mains line that comes out of the main power switch, but before the boiler. GAGGIA Classic 2021 550.00 , : PID KIT 129.17 , Top Box 35.00, OPV KIT . But nothing prevents you from using the PID and thermocouple as a temperature indicator. The biggest problem was the fact that the brew water control did not work: the SSR was never switched on by the thermocouple output. CONCLUSION! You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. Please let us know if theres a way to show our gratitude if theres a charity or cause we can donate to for you putting this guide together. Some shops are quoting $80.00 for the PID enclosure + lid.
