I am going into speculation mode here I wonder if your Gaggia came with the steam and brew thermostat positions reversed? Is this typical? Shall I change the P,I and D parameters manually and what is your suggestion to start with? One end is connected to the mains connector at the back (where it is showing N sign), the other end is connected to the back of the on off switch (as you showed on the picture above). How to install a pid on the gaggia classic pro. In it's current revision, the Arduino board is still powered via USB so there needs to be an opening to plug in the USB cable. Note that according to this video: https://www.youtube.com/watch?v=UETVv0qgz-w, you can switch the C-100 between Celsius and Fahrenheit. Did you try with the SSR unit 40 DA or 40AA? START NOW KIT-GG Installation Guide Version 1.3 Auber Instruments, 730 Culworth Manor, Alpharetta, GA 30022 e-mail: info@auberins.com Tel: 770-569-8420 www.auberins.com This is a PID controller kit installation guide distributed solely to our clients, who have purchased the KIT-GG kit. however the one SSR is nice and the modification gives upgraded steam with the solder mod. Thanks for your time. add to list. Always work with the Classic unplugged. You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. Chris, do you recall what size flat head screw was used on the 3d printed box for the REX-100?

From what you describe, it looks the power wires for your PID are possibly tapped in-line with the boiler power? The pump is not wired in series with the Heating element so Im not sure what is causing this. The little red collar shows the location. Tags Wheel For Containers and Boxes 3D model 3D printa. It should be placed as close to the left-hand side of the Classic as possible. This is VERY important! 103 or 105 is good. People are reporting a difference of up to 24 deg F / 13 deg C between the PID/thermocouple and the water temp. 1 RELAY alarm: Normal open, capacity 250V/3A AC or 30V/3A DC 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. However with the new steaming alarm system, I get a decrease around 10 degrees in steaming temperature as soon as AA SSR shuts down the boiler at the temperature I set, even it turns on right away (my setting is AL:156 AH:155 degrees Celcius). (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)? Maybe this will help? Ive been having trouble steaming milk lately, and wonder if there might be something wrong with the thermostat in my machine, wiring problems extending to this as well, or the steam valve might finally be needing a replacement. But, I still get loads of steam and spray before it settles down. 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. In this video I'll install a PID unit on my Gaggia Classic Pro. Thanks in advance for any reply! Hi Brian. One question, Ever thought about adding a pre infusion feature? The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. Maybe Im missing something? Same with the adapter screw. I have changed the default value of the SL parameter to work with the RTD sensor (K thermocouple was default). I guess I could revert the machine and see what I get. Open Source PID for Gaggia Classic and Classic Pro espresso machines. I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. It was impossible to see without getting down into the wire harness. It just overrides the PID and heats up the boiler to the factory preset steaming temperature.Links to parts [None are affiliate links]https://bit.ly/3gL9c95 - XMT 7100 PID unithttps://bit.ly/3xgAHhc - PT100 precision temperature sensorhttps://bit.ly/3wnZD6l - Fotek solid state relay 25Amphttps://amzn.to/3xamPFg - cable sleeve (different widths available)https://amzn.to/2RSAge0 - magnetic tape (example link, different widths available)https://www.thingiverse.com/thing:3671244 - 3D printed case file (print this locally)https://bit.ly/3pPphP0 - the unattractive aluminium enclosure if you wish to go that routeYou will also need:1. Based on several comments, the wiring varies between units, even though they are the same model. Either way, you are looking at a lot more complexity and cost. Even with a perfect offset, you would also need to also take into account the temperature offset between the boiler and the portafilter. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. You can only buy them as spare parts. Thanks. Thanks heaps for the detailed instructions. When I put everything back together, my machine started shorting out and tripping the circuit breaker on . Both shades and auber use the alarm 1 & 2 though with different PIDs for steam with upper limit & lower limit. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. 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-. gaggia classic pro pid installation guideAUBER PID for gaggia classic proThis is a walkthrough / guide on installing an Auber pid on the gaggia classic pro. The result was overshoot of up to 18C and an inability to return to the setpoint temp, 105C, unless I shut everything off and restarted. To set the target temperature, press the Set button on the front of the panel. I havent lowered brew pressure to 9 Bars yet so perhaps changing that would level out my pump pressures? 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. My PID is just held on by the clip on the side of the 3D printed box. If your connection is down to just a few strands, that will generate heat. Hi Chris, 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 Thanks a lot for the answer. I managed the brew side PID and digging in for the steaming side, using PID alarm function of my XMT 7100 unit. Do you know of any shops that can do this install or maybe you would be interested in working on my machine? Your Gaggia would be in steam mode by default, you would never have to switch on steam mode. Mains is house current. 40 A SSR; Display; Components. Nevertheless, I will take a look and see what values my controller is set to. Did you have any problems or stumbled upon anything unexpected? Not sure why that was the case. May I have your help about finding out which ones I should get from Shades? Publicado el sbado, 1 de abril de 2023 . Hi Paul. 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. This design is intended to be as simple as possible in terms of the installation, and requires minimal modification to the Gaggia machine. And anything is going to be a huge improvement over the thermostat that the PID replaces. Recently purchased and upgraded Gaggia Classic Pro from Whole Latte Love in late November, and built/installed the Gaggiuino mod myself in February. What you describe looks very much like the steam thermostat cycle. Thus brewing circuit needs to be connected directly to the heating element, not over steaming circuit. 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. I printed everything using Inland PLA+ filament. That being said, the original brew thermostat is supposed to be 107C, so could perhaps reach even higher temperatures? 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. Maybe this could serve instead of trying to find an M4 thermocouple. My problem is, unlike Rancilio Sylvia, heating element of Gaggia Classic Pro seems impossible to connect without cutting cables. Thanks in advance. Hi Brian. 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 attached the thermocouple using a spade connector to a spare pin on top of the boiler block. I am glad this article helped. Also really awesome write up. MY GC does the same thing, the pump tone changes when the boiler is heating. The code is reasonably well commented internally and variables are named such that it should be easy to find values you may need to change for your specific implementation, such as which pins have buttons assigned to them or the output pin for the SSR. Marca: Gaggia: Capacidad: 72 Onzas: Color: Acero inoxidable cepillado: Dimensiones del producto: Input. Most guides recommend connecting the SSR to the Gaggias (metal) body with some thermal paste, and this mount then serves as a heat sink.
