Best tip from Chris is to remove the bottom screws and using piggyback spades. However I now need to connect steaming and brewing circuits in parallel rather than serial because steaming circuit will not be closed unless I turn on steaming switch and supply power to steaming SSR. And this is the thermometer out the back. Hi Eddie. Posted by 4 years ago. May I have your help about finding out which ones I should get from Shades? Other than that mine was a fairly straightforward procedure with no trouble at all. I 37 All other variables aside, once you get a temperature that gives you the results you want, you will be able to get those results again, and again. I have briefly thought about pre-infusion but the REX C-100 is not capable of this. PID KIT for Gaggia Classic Pro 2018+ & Classic & Home, Pre-infusion $209.99. did the REX-100 require most of the default setting to be changed or is it similar to changing like shades PID or Auber PID. 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. You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. I dont want to void my warranty. brew thermostate. Black case : Currently out of stock! The PID unit did not turn on using the same terminal of your machine. Should I get the Auber Instruments PID kit w/ pre-infusion or w/ steam control? 5. 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. I am now waiting for my PID unit and thermocouple with M4 head to arrive this week. To do this, loosen the nut connecting the steam wand to the steam control assembly. 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 do not want to risk damaging my machine because of this. Should this be cause for concern, maybe caused by an error in wiring the PID? Ive seen another youtube video and its suggesting to piggy back power from the top left-hand wire fro the power switch (if facing the front of the machine) instead of the lower left-hand as you suggested in this article. However with the new steaming alarm system, I get a decrease around 10 degrees in steaming temperature as soon as AA SSR shuts down the boiler at the temperature I set, even it turns on right away (my setting is AL:156 AH:155 degrees Celcius). You need at least 20 amps. Hi Murat. (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. 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. Do the same with the other connector wire. Hi Evan. If in doubt, sit it out, and get some help. UNBLOCKING. Is it possible, despite setting the temperature to 102 degrees Celsius as SV, to actually run GCP much hotter due to incompatibility of the PID and RTD? (I am not testifying to the quality of the shots! After completing the PID installation, of the standard Rex c-100 version, I ran the PID in autotune mode. But that also seems fiddly. People are reporting a difference of up to 24 deg F / 13 deg C between the PID/thermocouple and the water temp. Hello Chris, If so, any idea how it can be achieved? It can be installed on Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espressomachines. I purchased an AC to AC SSR (SSR 40AA) which will stabilise steaming temperatures in much smaller margins than the original steam thermostat. From what I gather, youre located in the lower mainland (B.C.)? Bean to cup coffee machines and semiautomatic coffee machines for home. https://wiki.wholelattelove.com/File:GAGGIA_CLASSIC_2019_Wiring_Schematic.pdf This is a PID controller for the Gaggia Classic by Auber Instruments.This PID controls water and steam temperature. 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. Both shades and auber use the alarm 1 & 2 though with different PIDs for steam with upper limit & lower limit. Ive set the Sn value to pt for the PT100. 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. Thank you very much if you find the time to answer me . As in, temperature was set, changed, maintained for pulling shots, as well as steam. robert kujawa 348 subscribers Subscribe 85K views 1 year ago In this video I'll install a PID unit on my Gaggia.

And once you start considering adding in a power supply, you might as well go for a PID. Are the steps here suitable for older machines like mine? Mains is house current. 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. EN. Ive seen the steaming power on the classic remains solid from 125C and up, anything below that results in mediocre steaming power, which makes me wonder if I just have an aftermarket part that shouldnt be on this machine, or is just signs of imminent failure. 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. Hi Rusty. Hi David. Submit. . Hi Chris, I can actually taste the sweetness for the first time. If you have the regular version (RI9380 120V, or 240V), you DO NOT need this wire.

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). The operation is the same as the unmodified Gaggia machine. Your wiring looks right. When I say old, it is still unused new in the box. Regulate the standby coffee water temperatureto within 1 (F or C) accuracy. Based on several comments, the wiring varies between units, even though they are the same model. Do you think this makes a difference? 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. One end of the wire should be a male disconnect connector, and the other end should be a spade connector. This is probably the most difficult part of the installation. The C100 steps down mains voltage to 12v to power the SSR. You should be able to find the switched mains with the help of a multimeter. Or buy a machine with a built-in PID. I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. I hope you enjoy your upgraded GC as much as I do mine! I would not try anything without checking first. however the one SSR is nice and the modification gives upgraded steam with the solder mod. The solution is PID control via means of an industrial temperature controller; this is a common modification amongst the Gaggia and Rancillio community. it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. With a PID controller added to the heater control circuit, brew water temperature can be controlled to within 1 accuracy. Yes it is normal for the brew light to blink like this after you install a PID. I completed the installation last night and like you it too me about 5 hours But this included cutting a hole in the case stainless steel case to mount the PID controller internally, and that was probably the most time-consuming and difficult thing. Brass is soft and easy to drill, and all the adapter needs to do is provide a connection between the thermocouple and the boiler, so there would be no hard in doing this. Thanks in advance, this was a huge help! If you need to replace the PID controller, please contact us. PID Modification by Auber Instruments' Customer. Its not a sensor, it doesnt send any information, it just switches on an off, at setpoints that you cant adjust. Wear a glove when reaching in from below, otherwise bloodletting is likely. Im sorry about that, Eric. Do you know how to do this? Thanks for the info, D. Your experience further goes to show that there is no standardized wire color coding in the GCP, even though black is usually hot and white is neutral. I think this would be the most important parameter of the build, obtaining the correct temp of the water. If your connection is down to just a few strands, that will generate heat. It shows that neutral cables coming from thermostats are connecting each other under the steam switch but mine are connected under the main switch. Re-attach the boiler with the four bolts, re-attach the steam wand, push on the steam knob, and put the lid assembly back on, without forgetting to re-connect the two ground wires. It has been working flawless for the most part, but seen a few issues that havent seen before. I think one of either is the one which Shades of Coffee is using. . Looking forward getting your thoughts and ideas 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. on orders over $49. Thanks again for all your support. Cross referencing with the with the manual confirmed that the stickers had been reversed.

The grommet is used where the wires go through the chassis. Maybe this will help? $136.08. i set an upper an lower limit on alarms. different wiring though. Thats what Auber and Shades use, although they make their own. Also, the PID generates almost no heat, because the work is done by the SSR, and this is heat-sinked to the Gaggia. https://www.auberins.com. Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. A cheap multimeter is all you need. The only other thing I can think of is the relay. it is basically removing the main pump wire and re routing back to the PWM out. If you can share a picture of it, or a link, I can add it to the article. This kit doesn't control the steam temperature nor has the pre-infusion function. 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? 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? 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. Chris, this is a far simpler way to add preinfusion. Hi Chris. This PID controller kit is designed to retrofit into the European Gaggia Classic espresso machines made after 2015 (model# RI9403). In your paragraph for connecting the thermocouple, you write thermocouple connects to terminals 6 and 7.

Supposed to be faster in detecting temperature changes and more accurate with the measurement. Have you checked the temperature accuracy of your PID & Thermocouple? Hi Brian. Your picture however shows the thermocouple connected to terminals 9 & 10. I am not surprised that the steam kit made little difference. Hi Nish. The sensor has three wires: 1 x red and 2 x white. This does mean that you can only fill the water tank by pulling it out. [KIT-GG] Auber Instruments, Temperature control solutions for. The ability to make good espresso is one of the most coveted skills in the coffee world. Then use the left/right buttons to select the digits to increase and decrease, and the up/down buttons to change the digits. 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. In mine, correct terminal was crosswise of yours. Links. 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). on orders over $49. I am glad you solved the problem, Murat. From what I have read, the PID with the additional steam mode option does not improve things much. 7. Hi Justin. Accuracy: 0.2% 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. Hi Kraken. Please be sensible and install a grommet anyway! Also really awesome write up. Terrific write-up thank you for posting it! Sure enough, it powered up. The best way to find is: 1-Connect one cable to the mains connector at the back where it is showing N sign meaning Neutral. 3. Thanks. Fast, Free Shipping. 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! The 12 volt wires from the SSR connect to terminals 4 and 5. 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. Hi Tom. This product was added to our catalog on Friday 12 August, 2011. Likewise, you can use 22 awg for the connection between the PID and the SSR. Hi, thanks for the articely, it was great help to do the initial steps. Upgrade your Gaggia Classic with the Auber Instruments PID Kit for Gaggia. Close. See all. I think Mr Shades has managed to do this using only cables because I dont think he instructs anything to void the warranty. Please see the compatible model list below (Note 1 on the bottom). 3 months later, Ive finally set up the PID and honestly, its a gamechanger! (To be certain, the M4 is the correct one). Apologies for the long questions, thanks in advance! Hi Brian. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. When I started steaming at that point thermostat never shut down the boiler because temperature did not reach to limit of thermostat. Hey Chris, The KIT-GG is a retrofitting kit designed to control the coffee water temperatureon an espresso machine. I wondered if you ended up testing both in the end. Auber Instruments PID Kit for Gaggia Classic. Is it necessary to use a heat sink with the SSR installation? Trim, terminate and connect the wires you routed out the back of the Classic to the PID. https://www.youtube.com/watch?v=AoZuYaDq5yc, Thanks Jeff, thats a great video.
