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. That is indeed not normal. However, when I flip the gaggia power switch to off, the PID LCD screen remains illuminated. Theres also a M4 connected thermocouple wire on Amazon that arrived fast although it increased the whole cost compared to Bangood. Depending on the draw of the display (I saw 50mA somewhere), you could also try running it off a battery. See our 325 reviews on. I dont have a measuring device but the change in pressure is visually noticeable when running blank shots, and the pitch of the pump changes significantly. Im sorry about that, Eric. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. If you had to recommend a single display PID, which one would you steer me to? European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Always work with the Classic unplugged. . https://www.auberins.com. What you do get from the PID as per this guide in steam mode is the ability to see exactly what the temperature of the boiler is, so you can time your steaming to start during a heating cycle, which essentially gives you unlimited steam. But Ive downloaded the wiring diagram for my machine. -. the PWM needs a new wire to the where the pump wire was disconnected. Hi Eddie. I know wiring might be different colours but is everything in the same place? See all. Once warmed up, the recovery time is quick and the swing is fairly minimal. Even though the wires are insulated, as someone posted earlier, that metal is sharp and the vibration from the machine may eventually cause the insulation to fail and then your whole machine is a conductor. I plan to do this shortly for my old gaggia classic. I started with 103, and bumped it up to 105. 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. I think this would be the most important parameter of the build, obtaining the correct temp of the water. and its definately better than Auber which is NOT preinfustion by kicking off solenoid. (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. Then use the cursor keys to select the digits to increase and decrease. under the name replacement PID kit parts with very low prices. This works well with a PID for light & medium roasts. https://www.thingiverse.com/thing:4243840. If you want to defeat that auto-power-off feature, please add this piece of wire to your order. Possibly not the optimal position but was really easy to install and I knew Id only be getting a relative indicative temperature anyway. Auber Instruments PID Kit for Gaggia Classic. I have changed the default value of the SL parameter to work with the RTD sensor (K thermocouple was default). Hello Chris, Hi Peter. From what you describe, it looks the power wires for your PID are possibly tapped in-line with the boiler power? I do not suggest autotuning for this device because there is a huge improvement in temperature stability if you do the tuning by yourself. I deliberately avoided looking at the Mr Shades kits and instructions when I wrote this article, I dont want to steer people away from them. 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. Top Rated Seller Auber Instruments is one of eBay's most reputable sellers. Without offset the range is between 109-159, still too low. Mains is house current. I have to turn the set point on the PID down to about 85C to stop it boiling and getting steam and a great deal of sputter out of the portafilter. Did you make any changes to the setting of the PID? But it will require some dismantling of the work you have done. The PID itself draws very little current, so something like 18 gauge lamp cord would work. The Auber pretends to add a couple of things, but functionally, they're very much the same. You are right, its an M4 thread, not M3. Thanks again for all your support. It is still showing the M4 screw as the Crossed out/wrong one, and can be a bit confusing. I have a 2012 and am wondering if you had success and if the wires are as described in the article. Hi Murat, I agree, the PID is a gamechanger. With a PID controller added to the heater control circuit, brew water temperature can be controlled to within 1 accuracy. Close. 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. The digital LED display module is available in red or white. Again, as above, run this cable out the back, and leave it unterminated and longer than needed. Power input. Many thanks for such a comprehensive write up of your project. Previous topic - Next topic. GAGGIA CLASSIC - MODDED. Gaggia Classic Coffee Machine Modelo 3D TurboSquid 1036412. My problem is, unlike Rancilio Sylvia, heating element of Gaggia Classic Pro seems impossible to connect without cutting cables. This prompted me to look for alternate solutions. Hi Brian. https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_asin_image_o05_s00?ie=UTF8&psc=1, BOX PWM dimmer for preinfusion 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. PID Modification by Auber Instruments' Customer. It was impossible to see without getting down into the wire harness. Do you have any idea how to do? Wire colors and positions seem to vary. I 37 great article !!!! Plug in a mains-rated wire connected to a piggyback spade connector, and then plug the original neutral cable into the piggyback. The most I can say is these work for me, and are probably not optimum. Thanks in advance! Hi Eddie. If the wiring in your machine is different from our installation guide, please contact us. Do not undertake this procedure if you are not comfortable or uncertain. Fast, Free Shipping. 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 just finished installing the PID hardware in my Classic Pro today. Chris, i read some comments here about steam. 102 is even 3 degrees below my brew temperature. Hello, there is another model without SSR built in with name 7100 instead of 7200. 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. This product was added to our catalog on Friday 12 August, 2011. Its threaded on, and should not be very tight. Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. So far the temp range Ive seen when the heater cycles on/off (after ~30 mins of warming up) is ~90C to ~97C. This is the setup that I have assembled two days ago. These connectors are hard to reach, and are on very tight. 1. I am now waiting for my PID unit and thermocouple with M4 head to arrive this week. (To be certain, the M4 is the correct one). Please see the compatible model list below (Note 1 on the bottom). Home; Search; Log in; Sign up; Updates: Click here to visit our store! Hi Miguel. Net Weight: about 150g The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. Set the cover and screws aside. Please be sensible and install a grommet anyway! Did you try it? If you need to replace the PID controller, please contact us. If you are in the U.S. then mains voltage is 120V, which will not kill you (unless you have a pacemaker or are standing in a bathtub) but can give you a decent shock. EN. Either way, you are looking at a lot more complexity and cost. 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. This product was added to our catalog on Tuesday 26 June, 2007. But this kit doesn't fit the European model RI9403, which has a stainless steel boiler with a different thermostat mounting. 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. I decided to go the do-it-yourself route, ordering the parts separately, at a fraction of the cost of the kits. 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/. Bliss. I have an old Gaggia Carezza (uses the Gaggia / SaecoEF0030/A Boiler). 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 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. Thanks! It would be great to see how the machine is behaving without the PID, to get a baseline. An extended de-bugging solved the problem: the PID 12v circuit output was reversed, so changing + to solved the problem. Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. https://wiki.wholelattelove.com/File:GAGGIA_CLASSIC_2019_Wiring_Schematic.pdf MY GC does the same thing, the pump tone changes when the boiler is heating. 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. The rich body and complex flavor profile of a well-made shot brings the beans to life with a depth that other brewing methods fail to achieve. The Auber kit looks easy since I dont have time to build my own. Please see the compatible model list below (Note 1 on the bottom). 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. 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. Hi Nish. 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. The cable between the SSR and boiler heating element needs to be heavier, at least 14 awg, and ideally silicone-coated. I actually installed mine and then saw your thread, which is awesome to see other people using the same PID. Are the steps here suitable for older machines like mine? Hi , I followed the instructions but the PID starts up with some number and it doesnt look normal , LCD just keep blinking some numbers the goes of for a few seconds the I get some numbers for half a second, itso quick I cant tell what is displaying, could I have got the power wiring wrong or if the cable are higher AWG would it causes issue? Hi Gene. Ive been reading up many different values for the P, I and D, and im not sure where to start. Sign up for emails. 6 Reviews (6) $375.00. One last question: Auber and Mr Shades are calling their sensors PT100 while mine is K type thermocouple. Stock situation: Silver case : Last one or two!!! It really pays off to assume nothing, and test everything. There is definitely a falloff from the temperature reported by the thermocouple at the boiler and what you will measure at the group head. I did that exercise before installing the PID, behavior should be identical as that time. Is there a way to calibrate the read out close to the water out temperature. The REX-C100 should work out of the box, set for heating mode, with alarms disabled, and units set to Celsius. Temperature unit. To set the target temperature, press the 'Set' button on the front of the panel. What you describe looks very much like the steam thermostat cycle. Maybe this could serve instead of trying to find an M4 thermocouple. Well I ordered the wrong thread. 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. You said here that the to get an M3 thread for the boiler. A copy of the digital manuals, which includes a detailed installation guide, an operation manual, and supplementary documents. 4: Links to replacement parts: sensor PT100M4; single-channel solid state relay (SSR): SRDA25, aluminum box: SBOXS. Monitor and display the boiler temperature precisely. Hey. It should be placed as close to the left-hand side of the Classic as possible. In mine, correct terminal was crosswise of yours. GRAN GAGGIA PRIMING. $375.00. Thanks! This PID-SSR combination does away with the 12v connection, and uses three wires for the mains power and SSR, with one wire shared between mains and the SSR output. Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! This process involves working with potentially lethal mains-level voltages. 102 is way too low, you wont get useful steaming at that low a temperature. 0. Hi Anton. Double check that this is the neutral! Started by Rocky47, June 28, 2019, 01:16:33 PM. Awesome PID installation guide! 4.8. I went with an insulated PT100. 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. Cross referencing with the with the manual confirmed that the stickers had been reversed. UNBLOCKING. Hi Jun. Would you be able to post starting values for the PID kit please? Fast, Free Shipping. How to install a PID on a Gaggia Classic Pro - DIY, cheap and good looking! As for steam, the guide I wrote leaves the steam function completely untouched. best part it is inexpensive and as easy as OPV mod, here are the links: It should work as a replacement for the C-100 and SSR, but because the SSR is built into the PID, so your wiring will be a bit different. It is a really tight fit to get the REX C-100 PID inside the machine. 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. 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. I have to mention that coffee taste is good, not harsh or bitter. 3-Connect the other cable to the terminal on the on off switch, which is on top of or below the Live cable. Realized with your last comment you dont have the offset in place, my bad. https://www.vertex-qis.co.uk/Manuals/PT100_con.pdf. Silver case Black case TopBox with logo TopBox with gauge hole. Posted by 2 years ago. The fun of the PID is not just the great stability, but the ability to fine tune the brew temperature to your taste! Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm. Some people have done this by replacing the water filler funnel and 3D printing a replacement cover. The thermostat is a replacement, the original one burned around three years ago. You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. Leave as much of the thermal grease in place as possible. Your email address will not be published. Unfortunately, I didnt measure any temperatures for the un-modified machine. Thanks for putting it together, this has helped me a lot in figuring out most of my doubts with a PID project for a Gaggia. 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? On top of the original price tag, international shipping, taxes, duties and currency exchanges can make obtaining these kits time consuming and even more expensive. Perhaps Ill use a spare Arduino or FPGA to PWM the boiler while brewing as someone else was saying. 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? Based on several comments, the wiring varies between units, even though they are the same model. Note: I fully tested the PID, SSR and thermocouple on the workbench before final installation. Thoughts & musings from a product developer and manager. I am guessing that its caused by the current draw of the boiler heater. So you could measure water temp at the group head at 180 deg F with the PID set to 204 deg F. There is some interesting information here: https://coffeeforums.co.uk/topic/53319-what-temp-offset-are-you-using-with-your-pid/. i set an upper an lower limit on alarms. If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. But I would definitely read the instructions that come with whatever you receive! 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. I then thought what if? and decided to change the mains wires to the opposite terminals. Hi Andrue. Which Auber PID for Gaggia Classic? Hi Miguel. You need a 85-250V DC model, as the power will be coming from the Classic, which is mains-level voltage. Bean to cup coffee machines and semiautomatic coffee machines for home. Once these bolts are removed, the boiler can be moved around without having to disconnect any hoses or wires. Does anyone else have this kit? Run two 12 volt wires from the + and terminals of the solid state relay and out the back of the Classic, again using the same slot. My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). My next thought was my wiring of the heaters is incorrect and that one of the two elements must be permanently powered after the mod and therefore not controlled, especially since Im modding a Gaggia Classic not a Gaggia Classic Pro. CONCLUSION! The Classics over-pressure valve (OPV) is set to 14 bars, which is a pressure better suited to the use of pressurized portafilters. Note that my mod is to a Gaggia Classic, not a Gaggia Classic Pro. The steam mode drops to 102 before the power cycle kicks back in, with the valve open or closed. Most likely they will have the same connector types as the REX-C100, but its always possible that you will need different connectors depending on what you end up ordering. 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: 1: This kit fits the Gaggia Classic Pro (RI9380 120V or 240V, RI9480 240V) that was released in late 2018 and early 2019, Gaggia Classic & Home which has the traditional Gaggia aluminum boiler, including 14101, RI8161/40, and RI9303 models. Ill dismantle on a cleaning weekend and test the thermocouple again. 5. When the temperature stabilizes to within 1 degree of the target temperature, the auto-tuning is complete.
