Chris, this is a far simpler way to add preinfusion. Thermocouple included: M6*1 thread , K type , 2m cable And once you start considering adding in a power supply, you might as well go for a PID. I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. $149.99 . When the steam switch is turned on, the on/off temperature of the heater is controlled to 1 degree (F or C) difference as compared with the original thermostat's >10C (or 20F) difference. So I say go for it, but as Chris said, if you really dont feel comfortable with it, pass on the PID or try to find someone who can install it for you. if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple. If you have a regular version that doesn't have the auto-turn-off feature, (RI9380, 120Vor 240V), you DO NOT need this piece of wire. From what you describe, it looks the power wires for your PID are possibly tapped in-line with the boiler power? I have not changed any of the P, I or D settings on my controller. Do not over-tighten the adapter, it only needs to be finger-tight. But follow chriss advice and be careful and you should be OK. And also use a rubber grommet to route your wires through the slots in the back of the chassis. Shades. Hi Jeff. Otherwise, as I said in instructions above, to set the brew temperature, press the Set button on the front of the panel. Hello, there is another model without SSR built in with name 7100 instead of 7200. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. Gaggia Accademia. Hi Justin. Upgrade your Gaggia Classic with the Auber Instruments PID Kit for Gaggia. Its stimulated a lot of interesting discussion! https://photos.app.goo.gl/Xp37S3o3y6bqqrEk8 I went with an insulated PT100. (Gaggia Classic) Close. Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. GAGGIA CLASSIC - MODDED. Is this a typo on your part or a mistake on their part? It did take a few rounds to get it right, but it was successfully installed and functioning for a few months. Then the PID will only switch on when the boiler temperature drops below the target temperature. The PID kit you described should work, but like the C-100 kit the I used, the included thermocouple wont fit in the Gaggia Classic. Basically, instead of running the pump for a few seconds and then shutting it off (which dumps your pressure courtesy of the solenoid valve) you open the steam valve about 1/4 to half way, hit the brew switch and then slowly close the steam valve (about 5 seconds or so). The thermostat is a replacement, the original one burned around three years ago. I actually installed mine and then saw your thread, which is awesome to see other people using the same PID. If your connection is down to just a few strands, that will generate heat. Some shops are quoting $80.00 for the PID enclosure + lid. Hi Eddie. i set an upper an lower limit on alarms. These set the parameters and algorithms that monitor and control. . Hi Andrue. Have you checked the temperature accuracy of your PID & Thermocouple? Please see our Help Center's. I also think that you may have less difficulty reaching the thermostat, the 2019+ models have a lot less room to spare inside. Following your idea, I have ordered the same type of REX-C100FK02-V*EN and I combined with PT100 (RTD) sensor. Its threaded on, and should not be very tight. I was like WTF. $285.00. This is because the switch is connecting the terminals vertically when it is turned on. Ive been reading up many different values for the P, I and D, and im not sure where to start. Poll Moved Topic. Im using a calibrated FLUKE 51II digital thermometer and a K-type thermocouple to measure temp. Ive tried connecting these in various combinations but the PV readout is 3 or 4. Unblocking Solenoid Valve-Classic and Baby. Stock situation: Silver case : Last one or two!!! 2: The add-on item option "extra wire defeating auto-off timer" is for the Gaggia Classic Pro European model (RI9480, 240V), which has the auto-turn-off timer feature. I am going into speculation mode here I wonder if your Gaggia came with the steam and brew thermostat positions reversed? Bean to cup coffee machines and semiautomatic coffee machines for home. Replacing that wire= everything works perfectly now! You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. But that also seems fiddly. Adding pre-infusion would require either a different and significantly more sophisticated PID, or integration with something like a microcontroller. Monitor and display the boiler temperature precisely. The A vs E should not make a difference as I am not using alarm function, and am using it with a 3-wire PT100. This was such a great guide. To be clear, a PID can increases the likelihood of a consistent starting temperature. Hi Kraken. Home; Search; Log in; Sign up; Updates: Click here to visit our store! Ive been hearing the solenoid valve click several times while on steam mode as well, and the group head releasing steam on occasions, which also make me worry in terms of the wiring, or the parts just need replacement. it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. But I would definitely read the instructions that come with whatever you receive! Hi David. My next thought was that the controller wasnt reading the correct temperature. It looks like your GC is in steam mode. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. I am not surprised that the steam kit made little difference. 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). New to the forums, but I've been experimenting with espresso at home over the last year when my brother gifted me a used Gaggia Classic with an Auber PID. Leave the Classic powered on for at least 15 minutes. 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. 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. 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. Espresso Machines; Parts & Accessories; K type thermocouple, 0-500, 2m cable (6 feet). I was initially concerned about my wiring (and my GFI) but its reassuring to hear you have the same side effects. 6 Reviews (6) $375.00. If you have never done this before, know that you are working with live household current, and this can kill you. 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. Youre probably fine with either one. The silver box is coated with clear anodized aluminum with a brush-finished stainless steel front panel. Hi Gene. 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? Hello, thanks for the nice and valuable text. However I dont know if my unit is properly calibrated and/or has a proper offset. 3. It will depend on the beans you use, and your palate. Sure enough, it powered up. Thus brewing circuit needs to be connected directly to the heating element, not over steaming circuit. The countdown extraction timer contains three segments: pre-infusion pulse (Tp), soak (Td), and brew (Tb). A copy of the digital manuals, which includes a detailed installation guide, an operation manual, and supplementary documents. Using pliers to pull the connectors can pinch them on even more tightly, making them extremely difficult to remove. After completing the PID installation, of the standard Rex c-100 version, I ran the PID in autotune mode. I actually ended up getting the one you recommended. I am glad you solved the problem, Murat. Contact. brew thermostate. Thank you. If you can share a picture of it, or a link, I can add it to the article. 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? excluding VAT. But it will require some dismantling of the work you have done. The operation is the same as the unmodified Gaggia machine. Likewise, you can use 22 awg for the connection between the PID and the SSR. This prevents the high-pressure water from contacting the dry coffee powder which can create afast flow channel, ruiningthe brewing process. The steam mode has its own thermostat, which is very similar to the brew thermostat that the PID replaced, except that its temperature range is more or less as you described. If you had to recommend a single display PID, which one would you steer me to? You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. The documentation showed the default settings as P:30 I:240 D:60, but after tuning they were P:37 I:50 D:12. Net Weight: about 150g I dont bother with offset, once I have a temperature dialed in, it doesnt matter whether its measured at the boiler or offset for the group head. Bliss. P, I, d, controlling period, digital filter coefficient, and more (for control theory experts only) This steam blipping is a fairly common practice that people use to avoid boiler heater cycling, its just another way to do temperature surfing. Have you noticed any problem using REX-C100FK02 and RTD PT100? The KIT-GG PID controller kit replaces the function of the mechanical coffee thermostat. It will improve the consistency of the brewing even if you didn't tamp the coffee perfectly. Hi Brandon. Plug in a mains-rated cable connected to a piggyback spade connector, and then plug the original switched mains cable into the piggyback. 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. Do I need to make any adjustments to your procedure to make the PID handle the steam only (not caring about the group head)? I am glad this article helped. It is suitable for Gaggia Classic or other machines with a silver finish. There are other resources online as well. It seems the wiring varies even within model years, and between model regions. 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. I know wiring might be different colours but is everything in the same place? My problem is, unlike Rancilio Sylvia, heating element of Gaggia Classic Pro seems impossible to connect without cutting cables. I cant see why you couldnt. 0. Supposed to be faster in detecting temperature changes and more accurate with the measurement. I also checked to ensure that the physical steam switch is functioning correctly and the circuit is broken when it is off. With a PID controller added to the heater control circuit, brew water temperature can be controlled to within 1 accuracy. 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. best part it is inexpensive and as easy as OPV mod, here are the links: Chris, do you recall what size flat head screw was used on the 3d printed box for the REX-100? Thanks. Hi Chris, I appreciate your tutorials on the PID install. My plan is to install the Rex C100 first using your instructions. The on/off temperature can be adjusted by the user. We ship every business day from our two warehouses located in Milton, Ontario and Calgary, Alberta. Useful link. I dont own a multimeter. Based on several comments, the wiring varies between units, even though they are the same model. Thoughts & musings from a product developer and manager. 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. Yes it is normal for the brew light to blink like this after you install a PID. Ive seen the steaming power on the classic remains solid from 125C and up, anything below that results in mediocre steaming power, which makes me wonder if I just have an aftermarket part that shouldnt be on this machine, or is just signs of imminent failure. Using two 5-8 cm pieces of properly-rated wire (15 amps for North America), make two connectors to connect the thermostat wires to the AC terminals of the solid state relay. I hesitate to identify wires by their color, as the wire colors in the Gaggia seem to vary from year to year and from region to region. 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. But just like the kit I ordered, the threads on the thermocouple M8 according to the specifications are too big for the Gaggia. Im sorry about that, Eric. I ran the Autotuning function couple of times and I am always getting the following values for P, I and D parameters: P=620 , I=32, D=8. It would be great to see how the machine is behaving without the PID, to get a baseline. PID TEMPERATURE CONTROLLER W/ 30 RAMP / SOAK, KILN $81.98. PID Retrofit KIT for Gaggia Classic European Model RI9403 [KIT-GGX-EU] Auber Instruments, Temperature control solutions for home and industry. Its no secret that the chassis of the Classic has extremely sharp edges. https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd. Then use the cursor keys to select the digits to increase and decrease. Tighten one end of your connector down to one of the solid state relays AC (~) terminals and plug the other end into one of the disconnected thermostat wires. Locked Topic Sticky Topic . Hi Chris, Hi Dennis. Does this pid control both the group head water and steam wand? Warranty: 6-month limited warranty with a 30-day money-back guarantee is offered.
