Its getting very hot indeed so turned it off. Individually PID control parameters I recently acquired a Gaggia Classic with an Auber PID controller installed. You should see no or very low voltage between neutral and ground, and you should see household voltage between the hot/load and ground. Since installing the modification, I get a huge amount of steam and spray coming out of the portafilter when I first operate the pump so much so, that it sprays all over the worktop around the machine! The steam temperature controlallows the boiler temperature to be held at a tighter range during frothing. Do you think this makes a difference? Hello Chris, For the sake of piece of mind, I have ordered last night a K type thermocouple in order to replace the RTD P100 and close the open loop in my head about PID type and sensor. Double sided tape will work. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. However, depending on the seller, some settings may need to be changed. I would not make it without you. When I say old, it is still unused new in the box. To be clear, a PID can increases the likelihood of a consistent starting temperature. Its one more thing to plug in, but the upside is that it would be electrically isolated from the Gaggia. I should pointed out that the temperature ranges I was referring to were with the -8C offset on the PID. Select the preferred temperature unit so that all parameters are pre-set properly for you. 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 have any problems or stumbled upon anything unexpected? $375.00. 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. You need at least 20 amps.

That controller is an interesting find. Always double-check your specific models wiring terminal layout and numbering scheme. 7. 1. Hi Jeff. You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. as a cheap indicator to assist with surfing. Please see our Help Center's. different wiring though. I will purchase the PID kit with thermocouple and SSR from aliexpress and buy these rest small items from Mr. Also, the PID generates almost no heat, because the work is done by the SSR, and this is heat-sinked to the Gaggia. 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. Hi Jeff. I just finished installing the PID hardware in my Classic Pro today. Maybe Im missing something? Is there an easy way to set a brewing and steam temp? Hi Murat. This kit has a pre-infusion timer.

My experience, and that of others including a commenter on this article, is that I would not want to go lower than 103 on the Gaggia Classic. The black box has a durable powder coating. Do you think this makes difference? The preinfusion thing is a bit ridiculous, it just turns your pump on, off and on again. Please contact us if any questions. Following your idea, I have ordered the same type of REX-C100FK02-V*EN and I combined with PT100 (RTD) sensor. Monday - Friday: 10am - 4:30pm. (I am not testifying to the quality of the shots! I can do a more detailed writeup of what Ive done if anyone feels like helping me find out whats not working properly! The SSR is only rated for 5 amps. 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? Do not over-tighten the adapter, it only needs to be finger-tight. Pull off the steam knob and disconnect the steam wand. Thanks again for all your support. The PID will be more or less bypassed when the steam switch is on, it will just stop trying to heat because the boiler will be over the PIDs target temperature.

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. Try powering the PID directly from mains power, with just the thermocouple connected (disconnect the SSR). My Gaggia Classic uses 18 awg wire for every connection inside. Hi Justin. I agree, the PID is a gamechanger. I double checked all the wiring (inside and outside of the chassis) and eventually came to the conclusion that I had a faulty PID. Thanks! I hope you enjoy your upgraded GC as much as I do mine! Hello. Im sorry about that, Eric. Is it possible, despite setting the temperature to 102 degrees Celsius as SV, to actually run GCP much hotter due to incompatibility of the PID and RTD? Looking forward getting your thoughts and ideas 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. share. We ship every business day from our two warehouses located in Milton, Ontario and . Its stimulated a lot of interesting discussion! Whole Latte Love has a new video about preinfusion on the classic. Hi Chris, I completed the whole project both for brewing for PID and steaming via alarm. Maybe this could serve instead of trying to find an M4 thermocouple. Ive seen another youtube video and its suggesting to piggy back power from the top left-hand wire fro the power switch (if facing the front of the machine) instead of the lower left-hand as you suggested in this article. Hi, I just completed the DIY kit last night using your guide and it all went perfectly! Its no secret that the chassis of the Classic has extremely sharp edges. Please see the compatible model list below (Note 1 on the bottom). If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. This is a PID controller for the Gaggia Classic by Auber Instruments.This PID controls water and steam temperature. I am guessing that its caused by the current draw of the boiler heater. I hope thats ok. 2. Always work with the Classic unplugged. I am not sure exactly what you did when you moved the wires terminating on the bottom of the power switch. 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. it is basically removing the main pump wire and re routing back to the PWM out. Adding pre-infusion would require either a different and significantly more sophisticated PID, or integration with something like a microcontroller. Make sure that all the new and repositioned wires are cleanly routed away from the boiler and pump and any uninsulated connectors. A cheap multimeter is all you need. 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. The little red collar shows the location. Any ideas?

I would like to use it for steaming ONLY. I adjusted the calibration offset on the PID +5.5 degrees to read 212 degrees.Have you any suggestions of more accurately calibrating the PID and TC? Hi Jun, and thanks for the update. I installed an Auber PID on my Gaggia Classic earlier this year. 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. Since I cant control that, if you want to use it, you will have to parse the data: each line, after the headings, should start with the PID parameter (P, I, D) followed by the reaction of the controller. The Classics over-pressure valve (OPV) is set to 14 bars, which is a pressure better suited to the use of pressurized portafilters. Would you be able to post starting values for the PID kit please? The PID unit did not turn on using the same terminal of your machine. But that also seems fiddly. Keep the thermostat, in case you want to return the Classic back to factory condition. You can only buy them as spare parts. 6 Reviews (6) $326.00. Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything.

Might be easier for most folks to buy an M4 screw, type K, thermocouple direct vs trying to get the probe version then another adapter. The PID, RTD sensor and SSR (20 Amps) are installed on Gaggia Classic Pro 2018+. Previous topic - Next topic. Run this wire along the rest of the existing cables and out the back of the Classic, through one of the vent slots. Or is the only power available from the mains? If its closed it takes longer for temperatures to drop, but still goes to 102 before the it power cycles. If the wiring was done correctly, the PID should power up when the Classic is turned on. 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. There is no 12v anywhere in the GCP, its all mains power inside. Thanks for your reply: I think you are correct about the Gc being stuck in steam mode, but I never touched the steam switchs wires and reverting the top/bottom swap on the power switch didnt solve the issue. My P value is quite a lot different than yours. Most thermocouple calibration articles that I have read use ice water to calibrate to zero degrees C because the boiling point of water varies with altitude. Note: I fully tested the PID, SSR and thermocouple on the workbench before final installation. Im so thankful for this. Close the PID enclosure, and attach it to the side of the Classic. Have you noticed any problem using REX-C100FK02 and RTD PT100? I was able to create one using Lego bricks sitting around in the basement. Do you think its going to blow my machine if I dont do correctly? I wondered if you ended up testing both in the end. 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. I want to get a PID for my GC. This product was added to our catalog on Friday 12 August, 2011. I 37 Somebody else (Andrue) had also pointed this error out. This is an extra piece of wire for the European model of Gaggia Classic Pro (RI9480, 230V) with an energy-saving module, which turns off the machine after about 20 min if not used). Started by Rocky47, June 28, 2019, 01:16:33 PM. That being said, the original brew thermostat is supposed to be 107C, so could perhaps reach even higher temperatures? 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. If you have never done this before, know that you are working with live household current, and this can kill you. Chris has done a great job on this write up and its easy to follow. Mains is house current. If youre not comfortable installing this yourself, and taking on any followup maintenance, I think you would be much better off purchasing a machine that comes with a PID from the factory. 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. Shades uses an XMT7100 modified to run two SSRs: a DA for the brew temp and an AA for the steam temp. This steam blipping is a fairly common practice that people use to avoid boiler heater cycling, its just another way to do temperature surfing. You would probably blow the fuse in this controller/SSR within seconds. Their kit is convenient, and is the way to go if someone doesnt feel ready to take on a 100% DIY project. 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. If you used piggyback connectors, it should be a quick job to move the right one over to the correct switch terminal. After all this, I found that with the PID setpoint set at 94C, the brew temperature would rise to 94.5 and fall to 92.5 minimum. it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. The only suprise for me has been that installing steam kit did not help me much because brewing kit alone helped to have great steaming power by only watching temperature climb up to 150 degrees. 6 Reviews (6) $375.00. I have a 2012 and am wondering if you had success and if the wires are as described in the article. If you also need features such as steam temperature control, pre-infusion, and countdown timer, please checkKIT-GGPpre-infusion kit. sv4mzu 20, 2022 8:05 am.

You should be done! The biggest problem was the fact that the brew water control did not work: the SSR was never switched on by the thermocouple output. Our provided installation manual is based on the Gaggia Classic 2016 (model# RI9403/11). Hi Brian. Once these bolts are removed, the boiler can be moved around without having to disconnect any hoses or wires. 1. 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). The C-100 can accommodate only one sensor/SSR, so you would only set it for brew temperature. Espresso Machines; Parts & Accessories; Is this a typo on your part or a mistake on their part? 0. There are four buttons on the front: SET, run-program, up-arrow, down-arrow. The thermocouple that I ordered fit into the threaded adapter without any modifications. Then use the cursor keys to select the digits to increase and decrease. Hello again, I found out that connection I made was wrong. This gives the machine a whole new level of consistency, and gives you fine control over brew temperature. Please see the compatible model list below (Note 1 on the bottom). I started with 103, and bumped it up to 105. Id really love to do the install, however I have ZERO experience in electrical installation.
