I found that carefully pushing the boiler up gives better access to the thermostat, either from above, or by reaching up from below. Thanks. But just like the kit I ordered, the threads on the thermocouple M8 according to the specifications are too big for the Gaggia. My problem is, unlike Rancilio Sylvia, heating element of Gaggia Classic Pro seems impossible to connect without cutting cables. I am guessing that its caused by the current draw of the boiler heater. Its actually reading too high.. 98 deg against 92deg measured by both my oven thermometers. 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. Black case : Currently out of stock! Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) 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. the PWM needs a new wire to the where the pump wire was disconnected. Hi Chris, I am only using the Rex temporarily while working on a project with a Raspberry Pi (and the cost of the Rex was only a couple dollars when ordering the SSR), otherwise I would reprint the entire enclosure with the hooks built in. Cross referencing with the with the manual confirmed that the stickers had been reversed. Please be sensible and install a grommet anyway! 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. They are easy to unlock to get to all of the other settings, there are plenty of instructions on how to do this out there, but I didnt really need to go there. But I would definitely read the instructions that come with whatever you receive! PID Control Kit for Rancilio Silvia Espresso Machine, White LED $164.99. The PID will show the temperature, and be somewhat confused by its inability to reach its setpoint, however the PID is bypassed in the same way when the GCP is in steam mode. 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 plan to do this shortly for my old gaggia classic. No gross taste. And once you start considering adding in a power supply, you might as well go for a PID. Is there an easy way to set a brewing and steam temp? I have not changed any of the P, I or D settings on my controller. 103 or 105 is good. 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. I had no problem with my mod other than the stickers on the back of the PID were reversed, so the terminal markings were not correct. Espresso Machines; Parts & Accessories; I have read reports of measurements of up to 8 degrees C lower at the portafilter. What is the intra-shot temperature fluctuation that you are seeing on your machine with your PID setup? Read More. 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 . -. Hello, there is another model without SSR built in with name 7100 instead of 7200. This is a PID controller for the Gaggia Classic by Auber Instruments.This PID controls water and steam temperature. 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. Box color. As for steam, the guide I wrote leaves the steam function completely untouched. GRAN GAGGIA PRIMING. The REX-C100 should work out of the box, set for heating mode, with alarms disabled, and units set to Celsius. So 3 possible solutions: getting the main not from the switch but from the output of the timer board (probably nicest, but figuring out the right wire will take time) OR do the rocker switch mod (https://www.shadesofcoffee.co.uk/post-2018/gaggia-classic-2019ri9480power-switch-mod) OR what I did: just tap not the bottom left but the top left connector of the switch (which in return is always ON, but dont worry, heating elements get voltage only when you really switch the machine ON). Either way, you are looking at a lot more complexity and cost. If the thermocouple wire is too long, coil it up inside the machine, well away from the boiler or any uninsulated connections, using zip ties to hold the coil in place. Hi Nish. You can search on Reddit, a few people have made these modifications. 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). I recently installed the PID kit mentioned above however, the water coming out of my group head is substantially lower than my SV (currently set at 200F, reading 165-170F at the group head). I hope you enjoy your upgraded GC as much as I do mine! Likewise, you can use 22 awg for the connection between the PID and the SSR. Thanks so much for the awesome guide! While the steam switch is engaged, the PID serves to provide a temperature reading of the boiler, which is great, because you can use that temperature reading to time when to start steaming for maximum steam performance. Variants Coffee Only + Installation - No Coffee Only + Installation - Yes Coffee, Steam & Pre-infusion + Installation - No Coffee, Steam & Pre-infusion + Installation - Yes Quantity Free Shipping Parts For the European version of Gaggia Classic 2015 (RI9403, 240V) please checkKIT-GGX-EU. Do you think this makes difference? The Auber kit looks easy since I dont have time to build my own. Fast, Free Shipping. Does the PID generate enough heat to melt the Lego bricks? 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/. Chris thank you so much. Thermocouple included: M6*1 thread , K type , 2m cable The YouTube video from wll about replacing the boiler made the whole thing very easy. Which Auber PID for Gaggia Classic? You should see no or very low voltage between neutral and ground, and you should see household voltage between the hot/load and ground. save. Is 103 degree Celsius the best target temperature fit the PID? Try powering the PID directly from mains power, with just the thermocouple connected (disconnect the SSR). Youre giving up one of the two temperature readouts, so youll probably only see the actual temperature, as opposed to the target temperature, and I guess you can switch between the two with a button press. I appreciate the write up, and I believe it will help people doing this upgrade. Submit. I started with 103, and bumped it up to 105. Here are a couple of examples: Hi Chris, Pull off the steam knob and disconnect the steam wand. So the above instructions might not apply to the UK, I have the GC2019 but the live connection was the top right on the power switch when switched on, bottom left caused the PID to flicker and not work as expected, I fixed my issue but now the PID readout is 103 Dec but the water is 80 degrees, didnt think it would be off by this much. By doing this, the TC bead is pressed against the boiler housing at the point closest to the boiler water, and is assisted by the thermal transfer compound. Did you make any changes to the setting of the PID? You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. The kit is compatible with both 110VAC and 240VAC power. Please contact us if any questions. 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). Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. 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. Hi Kez. If the wiring in your machine is different from our installation guide, please contact us. that will make it where only one SSR is needed. Have you got any ideas what might be going on? We bring fresh high-quality coffee to the masses. Started by Rocky47, June 28, 2019, 01:16:33 PM. Thank you. 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. Does this mean that I have made the connection properly? Hi Chris, I am gathering / ordering the parts specified and was surprised to find out the price for 3d printing price spiked. So there is more or less no concern about PID heat and the PID enclosure. I found this M8 female to M4 male reducer: https://www.ebay.com/itm/284317077676. Shall I connect it to terminal 5 or 2 of the on-off switch? Useful link. Hi, I just completed the DIY kit last night using your guide and it all went perfectly! Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. Its threaded on, and should not be very tight. Heres how to install a PID on the Gaggia Classic Pro. Hi Brandon. Watching the steam temp with the PID is interesting (I know it has no effect on it, but it is cool to see how it reacts now) and it is definitely best practice to steam while its on its way up in temp, once it hits the set point it comes down for a while (mine settled around 130 before it started back up). Regulate the standby coffee water temperatureto within 1 (F or C) accuracy. 3-Connect the other cable to the terminal on the on off switch, which is on top of or below the Live cable. As for you steam mode question, if you followed this guide for installing your PID, the PID will have no effect on the the steam temperatures or functions. Replacing that wire= everything works perfectly now! 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 only buy them as spare parts. Posted by 2 years ago. excluding VAT. Please see our Help Center's. Please see the compatible model list below (Note 1 on the bottom). Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. 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. Thread in the M4 thermocouple adapter in the place of the thermostat. I used P:2,4 I:40 D:10 and Souf:0.2 which gives a shot stability around 2 degrees for single, 4 degrees for double shots. Thanks again for all your support. Your wiring looks right. Your Gaggia would be in steam mode by default, you would never have to switch on steam mode. Power supply : 90-265V AC/DC Hi Chris, thanks for the reply. Not really preinfusion, just an excellent way to crack the puck before your shot starts. Because the PID runs on mains voltages, an enclosure is required. Some shops are quoting $80.00 for the PID enclosure + lid. 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. Auto-tuning PID cooling/heating control 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. I am flattered, but will have to pass. I have a similar model, C100-Fk02-V*AN. (for a reasonable fee of course). If you have a 12v pid could you do everything as you have done except the mains wiring and instead wire the pid directly to an old phone wall charger for power? Hey. To set the target temperature, press the Set button on the front of the panel. Many thanks for such a comprehensive write up of your project. Manual Machine Shop. Like NEW Gaggia Classic Espresso w/ Grinder and Base - - 6758821731. I have installed the supply cable for PID unit using piggyback spade connectors. Net Weight: about 150g Hi peeps, finally got all the bits n pieces to do the Pid, brew & steam mod on the gaggia, does anybody have any general instructions for putting this all together? Fast, Free Shipping. European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Make sure that all the new and repositioned wires are cleanly routed away from the boiler and pump and any uninsulated connectors. 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. Perfect, came back here to ask this question! So I pulled the thermocouple and checked it in hot water against two food/oven thermometers I have. Plug in a mains-rated wire connected to a piggyback spade connector, and then plug the original neutral cable into the piggyback. Hi Chris Auber Instruments. However, depending on the seller, some settings may need to be changed. Thanks for the catch, I will correct the article. $149.99 . The C-100 will fit in vertically, with the screen facing up. (The Gaggia machine is not included in this listing). You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current. hide. Which Auber PID for Gaggia Classic? Its no secret that the chassis of the Classic has extremely sharp edges. The kit looks a lot like the one I ordered. If you have never done this before, know that you are working with live household current, and this can kill you. We ship every business day from our two warehouses located in Milton, Ontario and Calgary, Alberta. For me I start steaming when the boiler temperature reads 130 degrees C. So for others who are contemplating going for the extra effort of installing the steam PID, know that the return on investment of doing this is questionable, if not net negative. I want to get a PID for my GC. I would re-crimp any connections that look suspicious. The pump is not wired in series with the Heating element so Im not sure what is causing this. The Classics over-pressure valve (OPV) is set to 14 bars, which is a pressure better suited to the use of pressurized portafilters. Depending on the enclosure, you may need to insert the PID into the housing first. It did take a few rounds to get it right, but it was successfully installed and functioning for a few months. Left or right side if facing the front of the machine? Maybe then try QB-T7100 afterwards and if it works I will buy the external case which is sold seperately (QB looks nicer with small size and external case). The operation is the same as the unmodified Gaggia machine. I bought the PiD from Amazon referenced in a comment above and its working fine. I am thinking to upgrade my classic pro more compact version with below controller. Its pretty straightforward. It is still showing the M4 screw as the Crossed out/wrong one, and can be a bit confusing. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. I would not try anything without checking first. Hi Dennis. $136.08. This would also allow you to switch to PID-controlled brew mode simply by lowering the PID temperature. You can verify the SSR by disconnecting its AC terminals and checking that it is indeed turning on and off. I had to manually enable autotuning on my REX-C100 and i dont know if other values are screwed up or if its something else, since it really does seem like the boiler is getting power in bypass of whatever the PID is doing. 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. 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. A couple of zip ties come in handy here. Hi Jimmy. Chris, i read some comments here about steam. 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 have a 2012 and am wondering if you had success and if the wires are as described in the article. For those interested I just bought a cheap ($13) K-type thermocouple and thermometer (TM-902C) https://www.ebay.com.au/itm/224710871179. 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. Have you gone through the (three) menus on the pid , using the instructions of your pid. The C-100 can accommodate only one sensor/SSR, so you would only set it for brew temperature. Mains is house current. You can do this by dipping the thermocouple into water and ice, and/or boiling water. My problem is that since installing the mod, my machine gets way too hot and boils. http://facebook.com/HKCoffeeHome EspressoGaggia Classic !Gaggia Classic can give a good espresso shot . This is sold on amazon It has been working flawless for the most part, but seen a few issues that havent seen before. Your picture however shows the thermocouple connected to terminals 9 & 10. https://www.vertex-qis.co.uk/Manuals/PT100_con.pdf. Thanks for your time. 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. However, when I flip the gaggia power switch to off, the PID LCD screen remains illuminated. Thoughts & musings from a product developer and manager. (Gaggia Classic) I swear this is the last question I will ask today lol. I would not make it without you. Supposed to be faster in detecting temperature changes and more accurate with the measurement. Possibly not the optimal position but was really easy to install and I knew Id only be getting a relative indicative temperature anyway. Trim, terminate and connect the wires you routed out the back of the Classic to the PID. Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm.
