Please make sure you've downloaded them prior to uploading the code to your Arduino of choice. K type thermocouple, 0-500, 2m cable (6 feet). Hi Chris, r . I have read reports of measurements of up to 8 degrees C lower at the portafilter. Others have managed to also install the PID horizontally and cut out a hole in the side of the GC, but that still requires replacing the water filler funnel. By the way there are three options as 12V, 24V and 85-250V DC. Slip some heat shrink tubing over the thermocouple, and ideally dip the thermocouple tip in some thermal grease, then insert the thermocouple into the adapter. 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). My plan is to install the Rex C100 first using your instructions. It will also be completely reversible and much cheaper than ready made solutions!This clip can also be treated as a how-to instructional video for anyone wishing to go the DIY way. im trying to find out from shades why shades uses 2. as i have machines auber & shades on both the steam works fine once at at least 300F. Hi Jun, glad you found this helpful. 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. Do you think this makes a difference? Thermocouple: J,S,K,E,Wre3 ~ Wre25 I also cleaned the part of the group head that that gasket sits in. Connect the +/- leads from the PID to the SSR input terminals, paying attention to the polarity as these are DC. 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. The required parts are a PID controller, a solid state relay (SSR) preferably rated for 40 amps, a K-type thermocouple, a thermocouple adapter to connect the thermocouple to the Gaggia boiler, wire rated for mains voltages as well as some smaller gauge 12 volt wire, male and female quick disconnect connectors, spade connectors, and two piggyback spade connectors. My next thought was that the controller wasnt reading the correct temperature. Does this mean that I have made the connection properly? Perhaps Ill use a spare Arduino or FPGA to PWM the boiler while brewing as someone else was saying. 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. Hello Chris, I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. 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. Unfortunately, I didnt measure any temperatures for the un-modified machine. This process involves working with potentially lethal mains-level voltages. Realized with your last comment you dont have the offset in place, my bad. The PID values are not saved if you change them through the menu so if you find a tuning you like and want to change the defaults, you'll need to do that in the code and then re-upload it to the device. Have you got any ideas what might be going on? I would be glad if you have any recommendations. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. New - Gaggia Classic Pro/2019 PID kit - 1/32DIN single display $139.33 excluding VAT View Product Information Select Your Mounting option Silver case Black case TopBox with logo TopBox with gauge hole Stock situation: Silver case : Less than ten left Black case : Last one or two!!! Then the PID will only switch on when the boiler temperature drops below the target temperature. Individually PID control parameters I print with PLA filament, which has a much lower melting temperature than the plastic that Lego uses. About 60cm of FLRY 1.5mm2 cable to connect the SSR to the Gaggia4. Gaggia classic pro PID question. Feb 12, 2021. Thanks! I dont want to void my warranty. These connectors are hard to reach, and are on very tight. Hi all, I recently bought a Gaggia Milady secondhand. 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. Im on [emailprotected] . 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. There's a circuit diagram included in the repo. 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 Murat. The PID actually only attempts to achieve one temperature (brew temp), the second SSR bastardises a secondary output in order to achieve the second temperature (steam temp). Hi Jeff. 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? The Rex c-100 reads in Celsius only, would I be able to substitute this kit with: The LED on the SSR is functioning but no current can be seen. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. Please be sensible and install a grommet anyway! This wont be enough for the boiler heating element. Is this typical? Im sorry about that, Eric. Thank you very much if you find the time to answer me . Note that my mod is to a Gaggia Classic, not a Gaggia Classic Pro. This is the setup that I have assembled two days ago. To set the target temperature, press the 'Set' button on the front of the panel. 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. I would not make it without you. Your wiring looks right. This guide should generally also apply to the 2013 GC, but you must assume that any of the switch wiring that I describe will be different for your model year. Mains is house current. Gaggia Gaggia Classic Shower Screen (standard OEM) 54.5mm $6.40 Gaggia IMS Nanotech coated Gaggia Mesh Shower Screen 55mm - IMSDR324/NT $12.81 IMS IMS Baristapro precision filter basket (58mm) - Nanotec or Standard - 15g, 18g, 20g, 22g` $28.17 REPA Silicone Group Gasket 8.5mm (red or blue) $6.40 REPA Silicone Group Gasket 8mm (orange) $6.40 1 2 The factory settings have been working well for me, aside from a ~5 degree C overshoot when it first reaches the target temperature. 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. The SSR is only rated for 5 amps. Accuracy: 0.2% 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. Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) Optionally, you can add some sleeving to the wires running between the Gaggia and the PID. Hey Chris, No gross taste. Hi Chris. There is definitely a falloff from the temperature reported by the thermocouple at the boiler and what you will measure at the group head. Hi Nitzan. 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? Auto-tuning PID cooling/heating control There are other resources online as well. Gaggia Classic'teki stma sistemi basit mekanik termostatla altndan scaklk 85-105 derece arasnda gidip geliyor ve siz demlemenin hangi scaklkta balayp hangi scaklkta bittiini bilemiyorsunuz. Glad this writeup helped. Loosen the four bolts that hold down the boiler assembly. Based on several comments, the wiring varies between units, even though they are the same model. Make sure that all the new and repositioned wires are cleanly routed away from the boiler and pump and any uninsulated connectors. Thanks, David. Thanks. When I finished, the whole C100 display just got current only for a sec, then it went out. 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. Your email address will not be published. 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. Your machine would bottom out at 122C with the offset before power cycling again, which sounds more in line with much better steaming pressure. The same can be done with the REX C100 but you need one with all 8 screw terminals (the second SSR for steam uses the alarm function which needs terminals #6 and #7) and these two are missing on some REXs. Because there is very little information on how to install a PID on the latest generation of the New Classic (2018 and newer, also called the Gaggia Classic Pro in North America), here are instructions on to do this. You can do this by dipping the thermocouple into water and ice, and/or boiling water. 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. Do you think its going to blow my machine if I dont do correctly? PID example MAX31865 driver is finished. I would like to use it for steaming ONLY. I think Mr Shades has managed to do this using only cables because I dont think he instructs anything to void the warranty. Any ideas? An important part is that no internal cables/connectors were modified; all the connections were made by creating splitters using the purchased spade connectors. I can actually taste the sweetness for the first time. 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. Contrary to the Gaggia circuit diagram, Black is live, White is neutral, a minor issue. have you had any issues with the k type or have heard of this? 3. Yesterday I replaced the group head gasket. Tags Wheel For Containers and Boxes 3D model 3D printa. (for a reasonable fee of course). 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. I have installed the supply cable for PID unit using piggyback spade connectors. I have not changed any of the P, I or D settings on my controller. Main Output: SSR: Open circuit: 4V, Closed Circuit: 24V40mA DC 102 is way too low, you wont get useful steaming at that low a temperature. It seems the wiring varies even within model years, and between model regions. I printed everything using Inland PLA+ filament. About 60cm of 1mm2 (17AWG) cable to deliver power from the Gaggia to the PID 3. Ive attached an album with my wiring below; Ive literally had an engineer look at it and The Gaggia is 100% at its original state except for the power taps on the neutral at the plug, the live on the brew switch, and the thermocouple to SSR wiring: https://imgur.com/a/rc4xtfz. Heat the shrink tubing. Reddit and its partners use cookies and similar technologies to provide you with a better experience. But just like the kit I ordered, the threads on the thermocouple M8 according to the specifications are too big for the Gaggia. Pull the cover assembly off by pulling upwards, and disconnect the ground cables. I can only find vids and instruction for the pro (does anyone have links for the older version?) Mods for post 2018 - Gaggia Classic Pro / Gaggia Classic 2019 espresso machines View products Mods for pre 2018 - "Original" Gaggia Classic espresso machines View products sign up Thanks. Perfect, came back here to ask this question! My ECM Giotto "Phoenix" Restored by the Coffee Machinist in Melbourne, Australia.

Depending on the enclosure, you may need to insert the PID into the housing first. If you have never done this before, know that you are working with live household current, and this can kill you. Wire colors and positions seem to vary. 24,00 . I actually ended up getting the one you recommended. Connect the two leads you removed from the original thermal switch to the switched AC side of the SSR. Remove the thermostat.
