For espresso, 9 bars is the generally preferred pressure. Thank you for making it. We bring fresh high-quality coffee to the masses. Poll Moved Topic. Possibly not the optimal position but was really easy to install and I knew Id only be getting a relative indicative temperature anyway. 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). Unblocking Solenoid Valve-Classic and Baby. I decided that for me, its not worth worrying about. If you need to replace the PID controller, please contact us. https://photos.app.goo.gl/Xp37S3o3y6bqqrEk8 New - Gaggia Classic Pro/2019 PID kit - 1/32DIN single display $135.30 SHIPPING: We load new stock of PIDs on a Sunday, and they sell out very quickly (often within a few hours). I actually ended up getting the one you recommended. Pressure control could be super nice to have. Its pretty straightforward. 3 months later, Ive finally set up the PID and honestly, its a gamechanger! SSR control ready to connect external Solid State Relay to handle High current. Do you think this makes difference? There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. Thanks. If you purchased the kit from our website, you can download the manual zip file from our website by one of the following methods: Note: I actually installed mine and then saw your thread, which is awesome to see other people using the same PID. The C-100 can accommodate only one sensor/SSR, so you would only set it for brew temperature. 18 comments. under the name replacement PID kit parts with very low prices. They are easy to unlock to get to all of the other settings, there are plenty of instructions on how to do this out there, but I didnt really need to go there. Allow easy adjustment on the coffee water temperature. PID Kit for older plastic body Gaggia Classic. If you have a regular version that doesn't have the auto-turn-off feature, (RI9380, 120Vor 240V), you DO NOT need this piece of wire. Posted by 2 years ago. 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 KIT-GG is a retrofitting kit designed to control the coffee water temperatureon an espresso machine. Does the PID generate enough heat to melt the Lego bricks? The on/off temperature can be adjusted by the user. Please be sensible and install a grommet anyway! You said here that the to get an M3 thread for the boiler. Thanks, I see what you mean. It is the perfect place. Is P=620 maybe an overkill, as I havent seen such a big value at other places? on orders over $49. 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. Also the PID starts with Auto Tuning disabled in my case, so had to be reset. The PID kit you described should work, but like the C-100 kit the I used, the included thermocouple wont fit in the Gaggia Classic. See here for details. 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. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. Thats what Auber and Shades use, although they make their own. If not, can you think of any potential mistakes I made along the way? Hi Eddie. Hi Chris, i noticed you used the K type thermocouple with the M4. 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. 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. https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_asin_image_o05_s00?ie=UTF8&psc=1, BOX Thx, $136.08. Thanks. The most I can say is these work for me, and are probably not optimum. 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. It looks like your GC is in steam mode. Select the preferred temperature unit so that all parameters are pre-set properly for you. Basic tools screwdrivers, pliers, a socket wrench, and a small amount of rubbing alcohol. Thanks Alex! The pump can be stopped at any time by pressing the ">" key a second time. Brilliant article. Ill verify the cable, its one of the cables that came with the machine, so it could likely be the strands have slowly burned with time and just needs cutting and re-crimping, as you mention. 19K Items sold. Hi Chris I still have one question you may be able to answer. Was hoping to actually just install one of these: https://www.ebay.com.au/itm/264849127538 It was impossible to see without getting down into the wire harness. Fast, Free Shipping. One question, Ever thought about adding a pre infusion feature? When the temperature stabilizes to within 1 degree of the target temperature, the auto-tuning is complete. Fortunately, no damage done, and you can easily revert your changes. In a nutshell, the Gaggia Classic thermostat is replaced by the combination of the the thermocouple, the PID, and the solid state relay. I have an old Gaggia Carezza (uses the Gaggia / SaecoEF0030/A Boiler). Its not elegant, but does the job to give you a pretty good relative temperature to aid your temp surfing. It doesnt matter which thermostat wire is connected to which of the AC terminals on the solid state relay. This process involves working with potentially lethal mains-level voltages. The taste of a real Italian espresso everyday! One thing I would really recommend when anyone installs a PID system into the Gaggia Classic is to install a rubber grommet where the cables exit the machine. I have installed the supply cable for PID unit using piggyback spade connectors. Its actually reading too high.. 98 deg against 92deg measured by both my oven thermometers. Thanks in advance. By the way there are three options as 12V, 24V and 85-250V DC. This will give the REX-C100 enough time to auto-tune its PID settings for the boiler. Mains is house current. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. To find the neutral inside the GC, you have to test using a multimeter or voltage meter. Hi Chris, Ive followed these instructions exactly (thank you for your thoroughness) except for how the mains were tapped: I moved the two wires terminating on the bottom of the power switch to the top, and tapped them (as per another guide). Users can see the boiler temperature on the PID controller directly and also easily adjust the brew water temperature to suit their own tastes. Bliss. I ran the Autotuning function couple of times and I am always getting the following values for P, I and D parameters: P=620 , I=32, D=8. I know what I will be trying tomorrow , Hi, The idea of the chassis becoming live doesnt bear thinking about. This would also allow you to switch to PID-controlled brew mode simply by lowering the PID temperature. I am glad you solved the problem, Murat. https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd. Its no secret that the chassis of the Classic has extremely sharp edges. Once you are able use the PID temperature readout to determine exactly what the steam cycle is, you know when to start steaming for more or less endless steam. 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. This is a Used Black Appliances for Sale in Fairlawn OH posted on Oodle Classifieds. 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. This video clearly shows how to program in an offset on the Rex C-100: https://youtu.be/9aW8MfiKIPg?t=291. Yes it is normal for the brew light to blink like this after you install a PID. Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. Whole Latte Love has a new video about preinfusion on the classic. Auber Instruments PID Kit for Gaggia Classic. I have few questions for you about this setup. The PID, RTD sensor and SSR (20 Amps) are installed on Gaggia Classic Pro 2018+. I can actually taste the sweetness for the first time. 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. Tap the switched hot/load mains power: disconnect the lower left-hand (if facing the front of the machine) wire from the power switch. on orders over $49. You need at least 20 amps. 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. 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. Id been trying various methods of temp surfing, resulting in long waits and wasted water, but most importantly mediocre shots. Ive tried connecting these in various combinations but the PV readout is 3 or 4. If your connection is down to just a few strands, that will generate heat. We bring fresh high-quality coffee to the masses. If you have never done this before, know that you are working with live household current, and this can kill you. Adding pre-infusion would require either a different and significantly more sophisticated PID, or integration with something like a microcontroller. Only needs 2 x AAA batteries. Is 103 degree Celsius the best target temperature fit the PID? Disconnect the two connectors from the brew thermostat, which is located on the bottom left-hand side of the boiler as you face the machine. i ordered K type and PT100 both for M4. Make sure that all the new and repositioned wires are cleanly routed away from the boiler and pump and any uninsulated connectors. Hi Evan. The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. (Available for download after purchasing the kit. Hi Anton. I want to get a PID for my GC. By doing this, the TC bead is pressed against the boiler housing at the point closest to the boiler water, and is assisted by the thermal transfer compound. . One end of the wire should be a male disconnect connector, and the other end should be a spade connector. The grommet is used where the wires go through the chassis. Spent a relaxing boxing day fiddling around with this mod. that will make it where only one SSR is needed. I hope you enjoy your upgraded GC as much as I do mine! Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) Sure enough, it powered up. Once warmed up, the recovery time is quick and the swing is fairly minimal. 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. Otherwise, it all works properly now. Useful link. Hi Chris, shades uses 2 connecting one ssr thru the other for steam. ). Hi Dennis. Thanks a lot for the answer. CONCLUSION! It is suitable for Gaggia Classic or other machines with a silver finish. The only way to cut it is to unplug the machine. Thanks in advance, this was a huge help! I would not try anything without checking first. Always double-check your specific models wiring terminal layout and numbering scheme. Thanks for your time. The countdown extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). As the optimal brewing temperature is 90C to 96C depending on taste, this variance means the coffee can be over or under-extracted, or worse - variable. 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.
