Trim, terminate and connect the wires you routed out the back of the Classic to the PID. Monitor and display the boiler temperature precisely. This is probably the most difficult part of the installation. Regarding the M4 screw/ thermocouple, is it possible to amend the picture? I am guessing that its caused by the current draw of the boiler heater. Rancilio SilviaPID. Double check that this is the neutral! It doesnt matter which mains terminal is connected to hot and which one is connected to neutral. Leave the Classic powered on for at least 15 minutes. Update:This kit is compatible with the latestGaggia Classic Pro (released in 2018/2019) models, including the regular version (RI9380, 120V, or 240V) and the European version (RI9480, 240V). 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. That is confusing. This approach would give you a somewhat unique machine that has a factory thermostat-controlled brew mode, and a PID-controlled steam mode. Net Weight: about 150g There are four buttons on the front: SET, run-program, up-arrow, down-arrow. For the Gaggia Classic, taking into account the temperature drop between the boiler and the group head (5-8 degrees C), the PID target temperature should be set to about 103 degrees C or 220 degrees F at sea level. 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. Pull the cover assembly off by pulling upwards, and disconnect the ground cables. Hi Chris, thanks for the reply. Remove the thermostat. Looks like thats not an option. Terrific write-up thank you for posting it! 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. The kit includes all the parts and the materials to complete its function. did the REX-100 require most of the default setting to be changed or is it similar to changing like shades PID or Auber PID. Im so thankful for this. The same complexity applies to pressure control. I am not surprised that the steam kit made little difference. Gaggia Accademia. Maybe this could serve instead of trying to find an M4 thermocouple. Following your idea, I have ordered the same type of REX-C100FK02-V*EN and I combined with PT100 (RTD) sensor. Thanks Jimmy. Mains is house current. Neutral is the return path for the hot or load wire. Auber Instruments PID Kit for Gaggia Classic. I did that exercise before installing the PID, behavior should be identical as that time. Links. The kit is compatible with both 110VAC and 240VAC power. Shop. 4.8. Hello, I acquired and prepared all cables and SSR unit thanks to your well prepared title above. One thing I would really recommend when anyone installs a PID system into the Gaggia Classic is to install a rubber grommet where the cables exit the machine. Poll Moved Topic. I have read reports of measurements of up to 8 degrees C lower at the portafilter. Gaggia Classic Seamless PID Upgrade. 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. I will monitor it over the next few days, but if the coffee takes good, and the only thing I notice is the warmer cup tray, Ill be fine with that, better in fact! But that also seems fiddly. What is your coffee bean dark or light? PID KIT for Gaggia Classic Pro 2018+ & Classic & Home, Pre-infusion $209.99. however the one SSR is nice and the modification gives upgraded steam with the solder mod. Heres how to install a PID on the Gaggia Classic Pro. The YouTube video from wll about replacing the boiler made the whole thing very easy. It shows that neutral cables coming from thermostats are connecting each other under the steam switch but mine are connected under the main switch. The steam temperature controlallows the boiler temperature to be held at a tighter range during frothing. There is no 12v anywhere in the GCP, its all mains power inside. Espresso Machines; Parts & Accessories; 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. For the melted connector plastic, thats a sign of either a wire or a connector that is carrying too much current for its rating, or most likely, a connection between the wire and connector that is not as solid as it should be. However I dont know if my unit is properly calibrated and/or has a proper offset. By the way there are three options as 12V, 24V and 85-250V DC. Shall I connect it to terminal 5 or 2 of the on-off switch? You could definitely drill out the adapter a bit to get the thermocouple to fit. Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm. Be careful, the edges of the hole in the chassis are very sharp. Its no secret that the chassis of the Classic has extremely sharp edges. PID Control Kit for Rancilio Silvia Espresso Machine, White LED $164.99. Read More. Your Gaggia would be in steam mode by default, you would never have to switch on steam mode. Is 103 degree Celsius the best target temperature fit the PID? Somebody else (Andrue) had also pointed this error out. It looks like your GC is in steam mode. GAGGIA Classic 2021 550.00 , : PID KIT 129.17 , Top Box 35.00, OPV KIT . Hi Eddie. I dont want to void my warranty. 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 a similar model, C100-Fk02-V*AN. Or is the only power available from the mains? I actually ended up getting the one you recommended. I bought the PiD from Amazon referenced in a comment above and its working fine. 1. https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd. Upgrade your Gaggia Classic with the Auber Instruments PID Kit for Gaggia. Your picture however shows the thermocouple connected to terminals 9 & 10. I was able to create one using Lego bricks sitting around in the basement. The PID, RTD sensor and SSR (20 Amps) are installed on Gaggia Classic Pro 2018+. Thanks for the PID info. Fast, Free Shipping. 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. Thanks for the catch, I will correct the article. Its not elegant, but does the job to give you a pretty good relative temperature to aid your temp surfing. share. Please see the compatible model list below (Note 1 on the bottom). I went with an insulated PT100. For more than half a century, Gaggia has been supplying both coffee bars and homes with innovative, state-of-the-art coffee machines. Double sided tape will work. Hi Andrue. Thanks so much for the awesome guide! Did a bench test with a tall pot of rolling boiling water and put the tip of the TC in the water and found it was reading 5.5 degrees low. Auber Instruments PID Kit for Gaggia Classic. Do you know how to do this? Feel free to hang out, learn a bit, meditate, ride a bike, or perhaps it's just time to move on. Thanks, David. Unfortunately, I didnt measure any temperatures for the un-modified machine. The idea of the chassis becoming live doesnt bear thinking about. The preinfusion thing is a bit ridiculous, it just turns your pump on, off and on again. Also some pids come with a built in relay. Does anyone else have this kit? I would not try anything without checking first. 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. Thread the thermocouple wire through to the back of the machine, and out the same slot as was used for the other wires. Fast, Free Shipping. Unfortunately, no, you cant use the factory sensor. Contact. Hi, I just completed the DIY kit last night using your guide and it all went perfectly! Do not undertake this procedure if you are not comfortable or uncertain. The digital LED display module is available in red or white. I would like to use it for steaming ONLY. 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/. Is this just a matter of adjusting the offset of the PID? I can actually taste the sweetness for the first time. Is this a typo on your part or a mistake on their part? Nikola. Replacing that wire= everything works perfectly now! It did take a few rounds to get it right, but it was successfully installed and functioning for a few months. 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. Thread in the M4 thermocouple adapter in the place of the thermostat. 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. 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. If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. Any ideas? I havent lowered brew pressure to 9 Bars yet so perhaps changing that would level out my pump pressures? 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. 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. 1 RELAY alarm: Normal open, capacity 250V/3A AC or 30V/3A DC All of this really means that you should balance whatever temperature you end up reading against what youre tasting, because thats what matters in the end. Should I get the Auber Instruments PID kit w/ pre-infusion or w/ steam control? From what I have read, the PID with the additional steam mode option does not improve things much. Fortunately, no damage done, and you can easily revert your changes. Also noticed if you use the steam for the milk it takes a lot of time to go back down (10min) to the set temp(i do run water through the boiler to bring the temp down, but it floats at a higher temp for a bit), does the steam affect the PID calculation or dont I need to worry about it? Which one shall we buy? 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. Hey Chris, Auber Forum. PID TEMPERATURE CONTROLLER W/ 30 RAMP / SOAK, KILN $81.98. Just use a multimeter to find the switched mains, and you should be able to follow the thermostat wires. Thanks for the quick reply. To be clear, a PID can increases the likelihood of a consistent starting temperature. Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) Thanks. 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. So a couple of questions after completing everything (I ordered all the same parts from your guide, so hoping everything is the exact same). Previous topic - Next topic. 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. Hello Chris, Autotuning had resulted in shot instability up to 10 degrees during a shot probably because conditions during standby and during brewing are very different than each other. When the pump runs, it vibrates the chassis and it will be a matter of time before it cuts through the wiring insulation. 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. Even if that is the case, i dont have a clue as to why i would be in steam mode, since i didnt touch the steam mode button or its wires, i have already reverted my swap of the power switches wires (just from up to down on the same switch so that shouldnt have impacted anything) and ive validated that the rollback was correct with a multimeter. The boiler had been installed in such a way that it had pinched/nearly severed the upstream wire on the brew light. https://www.thingiverse.com/thing:4243840. 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. Hey Chris, But, I still get loads of steam and spray before it settles down. The lack of consistency pre-PID is frustrating, because you can get everything else right and still be at the mercy of the temperature determined by the thermostat cycle. Thanks. I have briefly thought about pre-infusion but the REX C-100 is not capable of this. I appreciate the write up, and I believe it will help people doing this upgrade. Looking forward getting your thoughts and ideas 100% Positive Feedback.
