I am glad you got your setup working Murat. Popular categories from this store. 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). Accuracy: 0.2% Resetting or Taking out a Brewing Unit for Cleaning. The way I wired the PID leaves it powered on as long as the main power switch is on. The C100 steps down mains voltage to 12v to power the SSR. You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. Shall I connect it to terminal 5 or 2 of the on-off switch? What is your coffee bean dark or light? Thanks, David. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. Thanks. This approach would make your machine a bit weird to someone who wasnt aware of what you did, as the brew function would be completely unusable without adjusting the temperature. 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. Thanks! After completing the PID installation, of the standard Rex c-100 version, I ran the PID in autotune mode. 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). Your Gaggia would be in steam mode by default, you would never have to switch on steam mode. Pull the cover assembly off by pulling upwards, and disconnect the ground cables. Hi Chris. The most I can say is these work for me, and are probably not optimum. P, I, d, controlling period, digital filter coefficient, and more (for control theory experts only) This is not a difficult mod. Note that according to this video: https://www.youtube.com/watch?v=UETVv0qgz-w, you can switch the C-100 between Celsius and Fahrenheit. It has a blue led not red like pictured.The kit works for 115 VAC and 240VAC. Individually PID control parameters Hello, there is another model without SSR built in with name 7100 instead of 7200. And this is the thermometer out the back. brew thermostate. You can take a look at this discussion about offset in the Gaggia Classic: https://coffeeforums.co.uk/topic/53319-what-temp-offset-are-you-using-with-your-pid/. I have couple of concerns with this setup and would like to kindly ask for your opinion: 1. Thread the thermocouple wire through to the back of the machine, and out the same slot as was used for the other wires. I dont want to void my warranty. Most assembly guides recommend using some thermal paste between the SSR and the Classic to ensure that any heat from the SSR is dumped to the chassis. Auber Instruments PID Kit for Gaggia Classic. This is probably the most difficult part of the installation. 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. Here are a couple of examples: Hi Chris, Because the wiring connections can vary between manufacturers, you should bench-test your setup before final assembly. From what I have read, the PID with the additional steam mode option does not improve things much. Brilliant article. Useful Video. Can anyone advise on the PT100 sensor setup? I can actually taste the sweetness for the first time. Pull off the steam knob and disconnect the steam wand. 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. The LED on the SSR is functioning but no current can be seen. 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. To set the target temperature, press the Set button on the front of the panel. Please contact us if any questions. Previous topic - Next topic. Hello. Thanks in advance for any reply! Its no secret that the chassis of the Classic has extremely sharp edges. This does mean that you can only fill the water tank by pulling it out. 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. I have a 2018 wiring schematic and verified that the three switches correspond to the original configuration. Is there a way to tap into +/- 12Volts inside the GCP? Read More. I am not surprised that the steam kit made little difference. Thanks. 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). If your connection is down to just a few strands, that will generate heat. Thank you for making it. When the steam switch is turned on, the on/off temperature of the heater is controlled to 1 degree (F or C) difference as compared with the original thermostat's >10C (or 20F) difference. Thanks again for all your support. I have briefly thought about pre-infusion but the REX C-100 is not capable of this. Once these bolts are removed, the boiler can be moved around without having to disconnect any hoses or wires. Pull the steam wand up and out of the Classic, and set it aside. Hi Chris, I appreciate your tutorials on the PID install. 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. Realized with your last comment you dont have the offset in place, my bad. PID Kit for older plastic body Gaggia Classic. 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 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. Leave as much of the thermal grease in place as possible. This kit has a pre-infusion timer. 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. Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) Where did you place the SSR? Gaggia Classic Seamless PID Upgrade. After autotuning, my values are: PID Control Kit for Rancilio Silvia Espresso Machine, White LED $164.99. Hi Jeff. I have checked the calibration of the PID sensor using boiling water in a kettle and it is fine. Auber Instruments PID Kit for Gaggia Classic. Thanks! Steam will still be controlled by the steam thermostat. Likewise, you can use 22 awg for the connection between the PID and the SSR. Thermocouple: J,S,K,E,Wre3 ~ Wre25 Wire colors and positions seem to vary. The biggest problem was the fact that the brew water control did not work: the SSR was never switched on by the thermocouple output. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. When the PID signals the SSR, as indicated by the brew ready light and the output led on the PID, the pressure coming out of the pump decreases, and then increases again after the PID out to the SSR turns off. Spent a relaxing boxing day fiddling around with this mod. Mains is house current. Posted by 2 years ago. I have a similar model, C100-Fk02-V*AN. I found this M8 female to M4 male reducer: https://www.ebay.com/itm/284317077676. From the factory, the GC has two thermostats, one for brew, which the thermocouple + PID + SSR replaces, and one for steam, which stays untouched. I had to manually enable autotuning on my REX-C100 and i dont know if other values are screwed up or if its something else, since it really does seem like the boiler is getting power in bypass of whatever the PID is doing. The idea of the chassis becoming live doesnt bear thinking about. I have only been drinking milk drinks and americanos because the shots I was pulling were always overly bitter, sour, or both, regardless of grind and quantity. Please see the compatible model list below (Note 1 on the bottom). There is definitely something weird going on. Bliss. Slip some heat shrink tubing over the thermocouple, and ideally dip the thermocouple tip in some thermal grease, then insert the thermocouple into the adapter. The little red collar shows the location. 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? EN. great article !!!! Add to cart Buy Now. Yes it is normal for the brew light to blink like this after you install a PID. Contrary to the Gaggia circuit diagram, Black is live, White is neutral, a minor issue. That being said, the original brew thermostat is supposed to be 107C, so could perhaps reach even higher temperatures? 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. The factory settings have been working well for me, aside from a ~5 degree C overshoot when it first reaches the target temperature. Cross referencing with the with the manual confirmed that the stickers had been reversed. Close the PID enclosure, and attach it to the side of the Classic. However, depending on the seller, some settings may need to be changed. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. I have installed the supply cable for PID unit using piggyback spade connectors. Users needto disable the parameter Tp, Td, and only useTb as a shot timer to pump a specific time. Its stimulated a lot of interesting discussion! Im wondering if this could somehow be the outcome of a bad SSR: Im not seeing current flow between the two AC terminals of the SSR when the PID is attempting to heat the boiler to the Set Temp. The YouTube video from wll about replacing the boiler made the whole thing very easy. 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, . Wear a glove when reaching in from below, otherwise bloodletting is likely. 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 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. Would you be able to post starting values for the PID kit please? My next thought was that the controller wasnt reading the correct temperature. Hi Jun, glad you found this helpful. 100% Upvoted. European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. MY GC does the same thing, the pump tone changes when the boiler is heating. The taste of a real Italian espresso everyday! Trim, terminate and connect the wires you routed out the back of the Classic to the PID. Nevertheless, I will take a look and see what values my controller is set to. Their kit is convenient, and is the way to go if someone doesnt feel ready to take on a 100% DIY project. If you have questions regarding ourcoffee kits, please check ourHelp Centerfirst. Note: I fully tested the PID, SSR and thermocouple on the workbench before final installation. Even with a perfect offset, you would also need to also take into account the temperature offset between the boiler and the portafilter. Pull the two wires that you removed from the thermostat up to the top of the machine, near the rest of the wires that run from the front to the back of the 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. The KIT-GG is a retrofitting kit designed to control the coffee water temperatureon an espresso machine. Auber Instruments PID Kit for Gaggia Classic. (Gaggia Classic) I swear this is the last question I will ask today lol. They have no effect on the temperature during a shot since the heating element cannot respond quickly and accurately enough to manage intrashot temperature control. 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. Leave the Classic powered on for at least 15 minutes. Does the wiring youve supplied automatically shut the PID unit off when you engage the steam switch? i set an upper an lower limit on alarms. K type thermocouple, 0-500, 2m cable (6 feet). I managed the brew side PID and digging in for the steaming side, using PID alarm function of my XMT 7100 unit. 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.
