Im thinking Id like to start with just a temperature indicator, to assist with the surfing. It has been working flawless for the most part, but seen a few issues that havent seen before. Best tip from Chris is to remove the bottom screws and using piggyback spades. Users can also bypass the timer to use the switch on the machine for manually controlling the brewing process. Hi Evan. This works well with a PID for light & medium roasts. 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). Allow easy adjustment on the coffee water temperature. 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. Thank you Chris for the awesome write up. The sensor has three wires: 1 x red and 2 x white. Also noticed if you use the steam for the milk it takes a lot of time to go back down (10min) to the set temp(i do run water through the boiler to bring the temp down, but it floats at a higher temp for a bit), does the steam affect the PID calculation or dont I need to worry about it? Is this typical? MY GC does the same thing, the pump tone changes when the boiler is heating. it appears i can configure the BERM REXC-100 like this as i entered the settings after i enabled alarm 1. auber uses 1 SSR & is simple. I actually installed mine and then saw your thread, which is awesome to see other people using the same PID. Left or right side if facing the front of the machine? New - Gaggia Classic Pro/2019 PID kit - 1/32DIN single display. Most thermocouple calibration articles that I have read use ice water to calibrate to zero degrees C because the boiling point of water varies with altitude. At a minimum, I think you would need the following: I dont see piggyback connectors on Mr Shades list, maybe those are part of the set of wires, but its not clear. 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. Wear a glove when reaching in from below, otherwise bloodletting is likely. I adjusted the calibration offset on the PID +5.5 degrees to read 212 degrees.Have you any suggestions of more accurately calibrating the PID and TC? Theres also a M4 connected thermocouple wire on Amazon that arrived fast although it increased the whole cost compared to Bangood. This product was added to our catalog on Friday 12 August, 2011. Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. Fortunately, no damage done, and you can easily revert your changes. 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. Is this a typo on your part or a mistake on their part? Supposed to be faster in detecting temperature changes and more accurate with the measurement. I have briefly thought about pre-infusion but the REX C-100 is not capable of this. Locked Topic Sticky Topic . Auber Instruments. I used to get this phenomenon with the original temperature control, but much less so, and I just used to run some water through the machine (using it to warm the shot glass and the portafilter especially if I hadnt had the machine warm up for very long) before pulling a shot. Started by Rocky47. great article !!!! Obviously the actual water temp will be different, but I can use this range to try and get a consistent temp when I pull a shot. 6 Reviews (6) $326.00. I have couple of concerns with this setup and would like to kindly ask for your opinion: 1. however the one SSR is nice and the modification gives upgraded steam with the solder mod. 19K Items sold. My Gaggia Classic uses 18 awg wire for every connection inside. Once warmed up, the recovery time is quick and the swing is fairly minimal. hide. It seems the wiring varies even within model years, and between model regions. Before replacing the thermostat, maybe check whether your PID and thermocouple are calibrated, before committing to buying more parts. Tap the switched hot/load mains power: disconnect the lower left-hand (if facing the front of the machine) wire from the power switch. The pump can be stopped at any time by pressing the ">" key a second time. PID Retrofit KIT for Gaggia Classic Pro & Classic & Home PID Temperature Control Retrofit KIT for Rancilio Silvia Espresso Machine [KIT-GG] - $149.50 : Auber Instruments, Inc., Temperature control solutions for home and industry Home :: Coffee Machine Kits :: PID Retrofit KIT for Gaggia Classic Pro & Classic & Home Coffee Machine Kits Product 4/21 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. Because there is very little information on how to install a PID on the latest generation of the New Classic (2018 and newer, also called the Gaggia Classic Pro in North America), here are instructions on to do this. Thanks. Then the PID will only switch on when the boiler temperature drops below the target temperature. I was able to create one using Lego bricks sitting around in the basement. These wires will be connected to the solid state relay later on, so they no longer need to be in the bottom of the machine. Please check KIT-GGX-EUinstead. Other than that mine was a fairly straightforward procedure with no trouble at all. A couple of zip ties come in handy here. Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! With a PID controller added to the heater control circuit, brew water temperature can be controlled to within 1 accuracy. Hope this helps. Id really love to do the install, however I have ZERO experience in electrical installation. All of this really means that you should balance whatever temperature you end up reading against what youre tasting, because thats what matters in the end. Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. But it will require some dismantling of the work you have done. I know what I will be trying tomorrow , Hi, When I finished, the whole C100 display just got current only for a sec, then it went out. Hi, I just completed the DIY kit last night using your guide and it all went perfectly! (PID Temperature Controller Meter Indicator, Jaybva Digital Universal Thermostat C and Fahrenhe F Display SSR and Alarm Output 40A Solid State Relay and Thermocouple Probe Heat Sink Included)? Sign up for emails. As for steam, the guide I wrote leaves the steam function completely untouched. Is it possible to do this with the GC factory temp sensor? I think this would be the most important parameter of the build, obtaining the correct temp of the water. If you have a 12v pid could you do everything as you have done except the mains wiring and instead wire the pid directly to an old phone wall charger for power? Hi Gene. This PID controller kit is designed to retrofit into the European Gaggia Classic espresso machines made after 2015 (model# RI9403). 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. Shades. Is 103 degree Celsius the best target temperature fit the PID? 100% Upvoted. Like NEW Gaggia Classic Espresso w/ Grinder and Base - - 6758821731. . And anything is going to be a huge improvement over the thermostat that the PID replaces. 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. Hi Joe. Ill be using a xmt7100 (modified) for two SRRs and also tweaked for 12v out for led mod any help would be appreciated. I cant see how this wouldnt be a thermostat problem, unless you somehow wired the steam thermostat into the PID, but you would have gone way beyond this walkthrough to do that. Indeed, not an option. Regarding the M4 screw/ thermocouple, is it possible to amend the picture? Auber Instruments PID Kit for Gaggia Classic. Youre probably fine with either one. it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. Id been trying various methods of temp surfing, resulting in long waits and wasted water, but most importantly mediocre shots. I would be surprised if your water is 80 degrees coming out of the boiler with the PID set to 103, but its possible, depending on the thermocouple youre using. Did you try it? Thanks Alex! But espresso is also among the more complicated ways to make coffee. Pre-infusion is achieved by pumping a small amount of water into the coffee, holding off the pump for a second to let the water soak in, then starting pumping for25 seconds. Auber Forum. Hi Chris Thanks. robert kujawa 348 subscribers Subscribe 85K views 1 year ago In this video I'll install a PID unit on my Gaggia. Display: Dual display for Fahrenheit(F) and Celsius(C) Im tempted to return the GC because I never used it prior to the mod and it may have been a pre-existing issue. Hi Justin. The GC comes from the factory with a simple thermostat that turns on at a certain pre-set temperature, and turns off at another pre-set temperature. Does the PID generate enough heat to melt the Lego bricks? The PID works after hooking everything up. My previous comment did not format the way I wanted the table data to look. Trim, terminate and connect the wires you routed out the back of the Classic to the PID. The biggest problem was the fact that the brew water control did not work: the SSR was never switched on by the thermocouple output.

And this is the thermometer out the back. 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 can do a more detailed writeup of what Ive done if anyone feels like helping me find out whats not working properly! Ive noticed that the PIDs output1 LED isnt illuminated after it climbs above my set temperature (103) but the boiler is getting heated up regardless. Your email address will not be published. Thanks Jimmy. That is indeed not normal. This process involves working with potentially lethal mains-level voltages. After autotuning, my values are: This will give the REX-C100 enough time to auto-tune its PID settings for the boiler. Based on several comments, the wiring varies between units, even though they are the same model. $326.00. Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. Also, the PID generates almost no heat, because the work is done by the SSR, and this is heat-sinked to the Gaggia. It can be installed on Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espressomachines. Hi Chris, Not sure why that was the case. So far the temp range Ive seen when the heater cycles on/off (after ~30 mins of warming up) is ~90C to ~97C. 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? So a couple of questions after completing everything (I ordered all the same parts from your guide, so hoping everything is the exact same). 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. This is not a difficult mod. This is because the switch is connecting the terminals vertically when it is turned on. 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 a lot for the answer.
