Thats an awesome enclosure. However, depending on the seller, some settings may need to be changed. Even with a perfect offset, you would also need to also take into account the temperature offset between the boiler and the portafilter. I plan to do this shortly for my old gaggia classic. ). Hi Kraken. Once warmed up, the recovery time is quick and the swing is fairly minimal. Thanks! Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. Temperature unit. I had no issues with the K type thermocouple. Neutral is the return path for the hot or load wire. My problem is that since installing the mod, my machine gets way too hot and boils. For the sake of piece of mind, I have ordered last night a K type thermocouple in order to replace the RTD P100 and close the open loop in my head about PID type and sensor. The Auber kit looks easy since I dont have time to build my own. This resulted in the PID not powering up even though the machine did. I have an old Gaggia Carezza (uses the Gaggia / SaecoEF0030/A Boiler). Update:This kit is compatible with the latestGaggia Classic Pro (released in 2018/2019) models, including the regular model (RI9380, 120V or 240V) and the European model(RI9480, 240V). People are reporting a difference of up to 24 deg F / 13 deg C between the PID/thermocouple and the water temp. I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. Also, the PID generates almost no heat, because the work is done by the SSR, and this is heat-sinked to the Gaggia. 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? Thanks! 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. Im sorry about that, Eric. Hi Miguel. GAGGIA CLASSIC - MODDED. Hi Ray. Thanks so much for the awesome guide! 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. Hi Eddie. 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.

Here are some pictures of the Lego enclosure: https://www.reddit.com/r/espresso/comments/owpfe7/i_made_a_lego_enclosure_for_rex_c100_pid/. The SSR is just a fancy switch and it should only be turning on and off, so depending on how you measure you may not see current. 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. Thanks Jimmy. The pump is not wired in series with the Heating element so Im not sure what is causing this. But, I still get loads of steam and spray before it settles down. I have read reports of measurements of up to 8 degrees C lower at the portafilter. 0. Ive followed these instructions and installed the mod using the REX-C100, SSR, K-type thermocouple and brass adapter linked in Chris excellent writeup (Thank you Chris). The taste of a real Italian espresso everyday! 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. 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. 5. Fast, Free Shipping. You can buy them at Ace hardware for about twenty five cents each. Wire colors and positions seem to vary. I have to mention that coffee taste is good, not harsh or bitter. I double checked all the wiring (inside and outside of the chassis) and eventually came to the conclusion that I had a faulty PID. Feel free to hang out, learn a bit, meditate, ride a bike, or perhaps it's just time to move on. Hi, thanks for the articely, it was great help to do the initial steps. I am glad this article helped.

Cross referencing with the with the manual confirmed that the stickers had been reversed. European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. 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. Your email address will not be published. Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm. You should now have two mains wires, two 12 volt wires, and the shielded thermocouple wire running out of the back of the Classic. 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. Likewise, you can use 22 awg for the connection between the PID and the SSR. It would be almost impossible for me to give you a complete list of the parts from Mr Shades that you will need, as it will depend on the PID and SSR models you order. Auber Instruments PID Kit for Gaggia Classic. This guide explains this well, and also explains what to do if your home wiring is not correct: https://diy.stackexchange.com/questions/195229/in-a-light-switch-how-can-i-tell-if-the-black-wire-is-really-hot-and-the-white. 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. Regarding the M4 screw/ thermocouple, is it possible to amend the picture? it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. The Auber pretends to add a couple of things, but functionally, they're very much the same. To set the target temperature, press the 'Set' button on the front of the panel. You can only buy them as spare parts. Users can also bypass the timer to use the switch on the machine for manually controlling the brewing process. I dont own a multimeter. The countdown extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). It is suitable for other colored espresso machines. Gaggia Classic Coffee Machine Modelo 3D TurboSquid 1036412. The best simple info I found was a table that summarized what INCREASING each of the PID parameters would do: which I used to adjust my settings. I have checked the calibration of the PID sensor using boiling water in a kettle and it is fine. 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. Hi Jeff.
