1. I have couple of concerns with this setup and would like to kindly ask for your opinion: 1. Remove the portafilter and water tank. About 60cm of SiHF 2x0,5mm2 cable connecting the PID do the SSR 2. 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. The PID itself draws very little current, so something like 18 gauge lamp cord would work. You should be able to find the switched mains with the help of a multimeter. Gravity seems to be working as expected in my case but you may decide to attach a magnet to the side of the box that touches the Gaggia for a more secure mount. I can actually taste the sweetness for the first time. This would explain the constant switching on and off. r . Im sorry about that, Eric. The image I used is wrong and confusing, and I have now updated it. 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. Its actually reading too high.. 98 deg against 92deg measured by both my oven thermometers. Pull off the steam knob and disconnect the steam wand. Hi all, I recently bought a Gaggia Milady secondhand. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. i heard from some that the PT100 with the M4 is more accurate. . D 9. Is it possible to do this with the GC factory temp sensor? 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. Ive tried connecting these in various combinations but the PV readout is 3 or 4. 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. Wanted to double check here for some observations a about three months after installing the PID. When I turn off, it goes back to zero. I dont want to void my warranty. I cant see why you couldnt. I have read reports of measurements of up to 8 degrees C lower at the portafilter. Have you written an article regarding installing a Gaggiuino mod? Can anyone advise on the PT100 sensor setup? These set the parameters and algorithms that monitor and control. Close the PID enclosure, and attach it to the side of the Classic. I have a question on the pid, it is normal for the brew light to blink (off and) while it stabilizes to the target temperature. Do I need to make any adjustments to your procedure to make the PID handle the steam only (not caring about the group head)? But Ive downloaded the wiring diagram for my machine. Works on both US 110V and EU 220V machines.Parts existing in the video:LED light kit: https://coffee-sensor.com/product/gaggia-classic-or-pro-water-tank-led-. When set up on my bench it tucks away nicely in behind out of sight and only needs to come out when in use. The grommet is used where the wires go through the chassis. 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. Is there a way to tap into +/- 12Volts inside the GCP? it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. For the Classic Pro, this requires either shortening the spring in the OPV valve through trial and error, or ordering a spring kit from Mr. 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. Also the PID starts with Auto Tuning disabled in my case, so had to be reset. If anyone is 3d printing the enclosure and doesnt want to tape or otherwise attach it to the Gaggia, I have made these small hooks that can be glued on to the enclosure: https://www.thingiverse.com/thing:4938828. (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)? Required fields are marked *. I was able to create one using Lego bricks sitting around in the basement. From what I have read, the PID with the additional steam mode option does not improve things much. The REX-C100 should work out of the box, set for heating mode, with alarms disabled, and units set to Celsius. under the name replacement PID kit parts with very low prices. Thread the thermocouple wire through to the back of the machine, and out the same slot as was used for the other wires. Double check that this is the neutral! Rotary encoder + built-in push button; MAX31865 (SPI) Steam button; Brew button; Output. You can buy them at Ace hardware for about twenty five cents each. The steam mode drops to 102 before the power cycle kicks back in, with the valve open or closed. And this is the thermometer out the back. For those interested I just bought a cheap ($13) K-type thermocouple and thermometer (TM-902C) https://www.ebay.com.au/itm/224710871179. I agree the ability to know exactly where the steam cycle is at is a nice convenience. shades uses 2 connecting one ssr thru the other for steam. https://www.amazon.com/gp/product/B00LODGP2E/ref=ppx_yo_dt_b_asin_image_o05_s00?ie=UTF8&psc=1, BOX gaggia_classic_pro_pid. If nothing happens, download Xcode and try again. It also means that you can only see the temperature and access the PID buttons from the top. I have noticed after PID installation that upper cup holder tray is getting quite hot during 8-10 min warm-up, which was not the case when I was using the original GCP setup. Hi Chris, Chris thank you so much. I tested the current with multimeter and it is showing DC 100V when I turn on the on-off switch. I just finished installing the PID hardware in my Classic Pro today. Have had the parts sitting around for months and no time to install! PID kit temperature control for Pavoni or Faemina lever coffee machine . The Rex c-100 reads in Celsius only, would I be able to substitute this kit with: I will purchase the PID kit with thermocouple and SSR from aliexpress and buy these rest small items from Mr. Hi Jeff. https://www.vertex-qis.co.uk/Manuals/PT100_con.pdf. It should be the power/mains line that comes out of the main power switch, but before the boiler. I decided to go the do-it-yourself route, ordering the parts separately, at a fraction of the cost of the kits. Connect one meter probe to ground (the GC chassis should always be grounded, otherwise connect to the green wire coming from the power socket at the back). Gaggia Classic & Classic Pro scales housing (BOM and models) Base Functionality Housings. Thanks in advance! Thus brewing circuit needs to be connected directly to the heating element, not over steaming circuit. Zip ties, heat shrink tubing, thermal paste, double sided tape, and a bolt and nut to attach the SSR are also required. 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. Gaggia Classic Mods PID kits, OPV kits, and other mod kits designed for various Gaggia espresso machines - drill down into kits relevant to your model of machine. Do you have any diagram of the wiringi cant understand how to switch on the steam circuit so the second SSR would not try to heat the boiler in parallel. I have few questions for you about this setup. Terrific write-up thank you for posting it! I found that moving the boiler up and to the side allowed me to get to the thermostat from the bottom really easily vs. the top. Hi Jun, and thanks for the update. Your wiring looks right. I have briefly thought about pre-infusion but the REX C-100 is not capable of this. The sensor has three wires: 1 x red and 2 x white. ESP32 IO. Because the PID runs on mains voltages, an enclosure is required. I drilled pilot holes for all the screws because my 3D printer has problems printing holes that small. 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. Ill try to get a new thermostat from a reputable place, see if that solves the problem, and if it remains then something else in the machine is wrong. I printed everything using Inland PLA+ filament. My plan is to install the Rex C100 first using your instructions. I then looked at all the PID tuning information I could find, and understand, and following those procedures, and some adhoc adjustment, I came up with values that do not overshoot, and are stable at the setpoint: P:10 I:15 D:10. 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. Thanks for the quick reply. Thread in the M4 thermocouple adapter in the place of the thermostat. 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. Nevertheless, I will take a look and see what values my controller is set to. Chris, do you recall what size flat head screw was used on the 3d printed box for the REX-100? You will probably want to drill pilot holes as well to prevent cracking the plastic. Hello, I am new to Gaggia world with my Classic Pro 2019 model and on the way of installing DIY PID for both brew and steam functions. Im so thankful for this. Hi Nish. If you are competent with basic workshop tools and can follow written instructions and photographs then you should be able to install the Gaggia Classic Pro PID Kit in around 2-3hrs and it requires only basic tools such as: A medium flat-bladed screwdriver A medium cross-head screwdriver Then the PID will only switch on when the boiler temperature drops below the target temperature. This gives the machine a whole new level of consistency, and gives you fine control over brew temperature. Display: Dual display for Fahrenheit(F) and Celsius(C) My steam bottoms out around 130 or so, and I dont start steaming until 135-145. I formatted the table, its very useful. Thanks for your time. 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. Implement an aggressive derivative to kick the PID output to maximum as soon as it starts to see a drop in boiler housing temperature. Test that everything is working before closing the machine back up. Yes it is normal for the brew light to blink like this after you install a PID. I used the same controller ( XMT 7100 ) which Mr Shades is selling. Screen Enclosure; Internal Component Housing; Additional Gaggiuino models can be found in the Gaggiuino Model Collection or on Discord in the #mod-3d-design-ideas channel. Spent some time playing with temps and pulling a lot of shots to dial it in and am very happy with the results. ESP32-WROOM32 - ESP32DEVKIT1; 40 A SSR . 1. Hi Chris, Free shipping. It can be installed on Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espresso machines. PID, Auto Shot Timer Add to Watch list. Do you observe the same temperature ranges? $399.00 + $19.99 . Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. In mine, correct terminal was crosswise of yours. (for a reasonable fee of course). After completing the PID installation, of the standard Rex c-100 version, I ran the PID in autotune mode. If in doubt, sit it out, and get some help. You would probably blow the fuse in this controller/SSR within seconds. However, at the cost of convenience, these kits can be relatively expensive. The cup warmer does seem a bit hotter than before (but have only used twice since installing, so Ill have to pay attention). I have a 2013 Gaggia Classic. If you used piggyback connectors, it should be a quick job to move the right one over to the correct switch terminal. I grabbed some screws from my parts bin, I took whatever I could find that was the same color as my filament, and that would fit the holes and hold reasonably well. Unfortunately, I didnt measure any temperatures for the un-modified machine. You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. . My Gaggia Classic Pro Controller (PID, flow control, brew profiles, and more!) Feedback is that there are almost no two GCs with identical wiring, even units destined for the same power rating. Thoughts & musings from a product developer and manager. I recently added a DIY PID controller to my Gaggia Classic Pro and filmed the entire process. 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. I have a 2012 and am wondering if you had success and if the wires are as described in the article. Tap the switched hot/load mains power: disconnect the lower left-hand (if facing the front of the machine) wire from the power switch. Hi Jeff. Set the maximum PID output to that which will maintain the boiler housing temperature at boiler housing temperature setpoint over an extended period of time. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. you could use this guide on another kit as all of the pieces here are required for just about any pid. Ill dismantle on a cleaning weekend and test the thermocouple again. The listing shows both M3 and M4 options, and I typed the first one when I wrote the article. Try powering the PID directly from mains power, with just the thermocouple connected (disconnect the SSR). A couple of zip ties come in handy here. You could definitely drill out the adapter a bit to get the thermocouple to fit. Always double-check your specific models wiring terminal layout and numbering scheme. One last question: Auber and Mr Shades are calling their sensors PT100 while mine is K type thermocouple. My only concern is the diagramm I downloaded from whole latte love shows different connections then what I have seen in my unit Is this typical? Please be sensible and install a grommet anyway! After autotuning, my values are: I have installed the supply cable for PID unit using piggyback spade connectors. You can search on Reddit, a few people have made these modifications. A tag already exists with the provided branch name. 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. My ECM Giotto "Phoenix" Restored by the Coffee Machinist in Melbourne, Australia. The pump is not wired in series with the Heating element so Im not sure what is causing this. So I would say yes, you should use a heat sink, but the Gaggia body conveniently provides you with that function. It will depend on the beans you use, and your palate. This is probably the most difficult part of the installation. Please make sure you've downloaded them prior to uploading the code to your Arduino of choice. Thanks again for the write up, Ill be playing around with temperature for the next week! GAGGIA Classic, parts, set, kit - Gasket Repair kit for Classic, Baby, Evolution. To be clear, a PID can increases the likelihood of a consistent starting temperature. By the way there are three options as 12V, 24V and 85-250V DC. Pressure control could be super nice to have. PID KIT for Gaggia Classic Pro & Classic & Home, Pre-Infusion - KIT-GGP (Red) PID KIT for Gaggia Classic Pro & Classic & Home, Pre-Infusion - KIT-GGP (Red) $319.00 RRP $362.00 SAVE $43.00 (12%) Location Availability Online: In Stock Sydney: In Stock Newcastle: No stock Hobart: No stock Add to Cart Wishlist Calculate Shipping Calculate Behind out of sight and only needs to come out when in use is set to Celsius pre-infusion but Gaggia!
