Its pretty straightforward. Have you noticed any problem using REX-C100FK02 and RTD PT100? If your connection is down to just a few strands, that will generate heat. The 103 is not a true 103, that is what is getting measured in the boiler wall, and there is also a temperature drop off between the boiler and the portafilter, so your final espresso temperature will be lower. I guess I could revert the machine and see what I get. Be careful, the edges of the hole in the chassis are very sharp. If the wiring was done correctly, the PID should power up when the Classic is turned on. This is the setup that I have assembled two days ago. It can be installed on Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espressomachines. That is confusing. The result was overshoot of up to 18C and an inability to return to the setpoint temp, 105C, unless I shut everything off and restarted. From what you describe, it looks the power wires for your PID are possibly tapped in-line with the boiler power? There are other resources online as well. Two different colors of the controller box are offered, silver and black. Hi Evan. These connectors are hard to reach, and are on very tight. Hi Kraken. I have found this PID kit here on Ali express and I think its the same one you fitted can you please tell me if this one is good to go, they got a 3 piece option and a 4 piece option so dont know which, I think the 4 piece option is because it includes a heat sink that you dont mention, so I assume I wont be needing it, can you please advise. Chris has done a great job on this write up and its easy to follow. This gives the machine a whole new level of consistency, and gives you fine control over brew temperature. . Thanks in advance, this was a huge help! Home; Search; Log in; Sign up; Updates: Click here to visit our store! 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 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. Replacing that wire= everything works perfectly now! 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. But will there be an upper limit to prevent the boiler from going near 365F and blowing thermal. Somebody else (Andrue) had also pointed this error out. Silver case Black case TopBox with logo TopBox with gauge hole. CONCLUSION! Range: -1999 to 9999 (depends on the input signal) I opted to follow my connections according to your picture, rather than that text. it works better than poor mans preinfusion described by wholelatte love & Lance in the youtube. Display: Dual display for Fahrenheit(F) and Celsius(C) Keep the thermostat, in case you want to return the Classic back to factory condition. I was initially concerned about my wiring (and my GFI) but its reassuring to hear you have the same side effects. If you also need features such as steam temperature control, pre-infusion, and countdown timer, please checkKIT-GGPpre-infusion kit. best part it is inexpensive and as easy as OPV mod, here are the links: They have no effect on the temperature during a shot since the heating element cannot respond quickly and accurately enough to manage intrashot temperature control. Links. 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). Thats what Auber and Shades use, although they make their own. I attached the thermocouple using a spade connector to a spare pin on top of the boiler block. Loosen the four bolts that hold down the boiler assembly. It doesnt matter which thermostat wire is connected to which of the AC terminals on the solid state relay. Add to cart Buy Now. Power supply : 90-265V AC/DC If you want to defeat that auto-power-off feature, please add this piece of wire to your order. (Gaggia Classic) Close. This is because the switch is connecting the terminals vertically when it is turned on. Thanks heaps for the detailed instructions. Im running into problems and I dont know if my REX-C100s starting values are the problem or if its my deviation with the wiring: Regardless of the temperature that i set on my PID, toggling the Gaggia on causes it to climb to 150-160C and then slowly decline to 118-125C, at which time it will heat up again. Hi, thanks for the articely, it was great help to do the initial steps. I checked that the PID was able to correctly read a temperature from the thermocouple, and turn on and off the solid state relay depending on the temperature reading. Thanks! 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. Without offset the range is between 109-159, still too low. I had no issues with the K type thermocouple. Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut. Did you have any problems or stumbled upon anything unexpected? I found that moving the boiler up and to the side allowed me to get to the thermostat from the bottom really easily vs. the top. Maybe this will help? From what I have read, the PID with the additional steam mode option does not improve things much. I am now waiting for my PID unit and thermocouple with M4 head to arrive this week. This is a Used Black Appliances for Sale in Fairlawn OH posted on Oodle Classifieds. On thing I realised is that Mr Shades does not allow purchasing the parts seperately unless you already purchased the kit as a whole. The C-100 can accommodate only one sensor/SSR, so you would only set it for brew temperature. I bought the PiD from Amazon referenced in a comment above and its working fine. There are four buttons on the front: SET, run-program, up-arrow, down-arrow. Hi, I just completed the DIY kit last night using your guide and it all went perfectly! Approach 1: Follow my writeup, adapting it to your models peculiarities, and then set the PID temperature to your preferred steam temperature. For questions, please contact us. 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. This way you are not losing any pressure via the solenoid valve, you are just reducing the initial pressure to the puck by venting some of it through the steam wand. Possibly not the optimal position but was really easy to install and I knew Id only be getting a relative indicative temperature anyway. 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. I just installed the pid on my Gaggia classic Pro following your instruction guide. I used lamp cord for this. AUBER. But I wondered if anyone has had the same problem and already found the answer! 3. Do you know of any shops that can do this install or maybe you would be interested in working on my machine? I have an old Gaggia Carezza (uses the Gaggia / SaecoEF0030/A Boiler). Heres a picture of the screws I used, with screwdriver for scale: Great article and development, congrats! The machine and PID were working great, my brother gave me a quick rundown of the PID basics (how it displays the boiler temp, how it pre-infuses, and then times a 30 second shot pull). Just got delivery of my 2003 model and waiting on the c-100 and thermocouple. (I believe it is currently on 5) Or shall I just keep it as it is, showing DC 100V when I turn the switch on? So there is more or less no concern about PID heat and the PID enclosure. Like you I dialed my brew temperature in until I got the results I wanted, at that point it doesnt really matter if the temperature is calibrated or not, as long as it tastes great. Wear a glove when reaching in from below, otherwise bloodletting is likely. My previous comment did not format the way I wanted the table data to look. How do I ensure that Im tapping the neutral mains? 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. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. I think Mr Shades has managed to do this using only cables because I dont think he instructs anything to void the warranty. Once warmed up, the recovery time is quick and the swing is fairly minimal. Do you think its going to blow my machine if I dont do correctly? Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. It would be great to see how the machine is behaving without the PID, to get a baseline. Thanks a lot for the answer. UNBLOCKING. You need at least 20 amps. 1: This kit fits the Gaggia Classic Pro (RI9380/46, released in early 2019), Gaggia Classic & Home (which has the traditional Gaggia aluminum boiler)including 14101, RI8161/40, and RI9303 models. 1 RELAY alarm: Normal open, capacity 250V/3A AC or 30V/3A DC Universal Input: Thermo Resistor: PT100, Cu50 . 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. If you go for a PID, you need to use a thermocouple. I know what I will be trying tomorrow , Hi, No gross taste. And once you start considering adding in a power supply, you might as well go for a PID. Based on several comments, the wiring varies between units, even though they are the same model. Fortunately, no damage done, and you can easily revert your changes. Is P=620 maybe an overkill, as I havent seen such a big value at other places? Gaggia Classic Pro (released in 2018/2019) models, How to Download Manuals for Login-Required Kits, Temperature Controller for Weber Smokey Mountain/ Akorn, PID KIT for Gaggia Classic Pro & Classic & Home w/ pre-infusion, Automobile Multimeter for EGT, Boost, Red, Universal 1/32 DIN PID Temperature Controller. Either way, you are looking at a lot more complexity and cost. Users needto disable the parameter Tp, Td, and only useTb as a shot timer to pump a specific time. For the European version of Gaggia Classic 2015 (RI9403, 240V) please checkKIT-GGX-EU. Hope this helps. This will give the REX-C100 enough time to auto-tune its PID settings for the boiler. From the factory, the GC has two thermostats, one for brew, which the thermocouple + PID + SSR replaces, and one for steam, which stays untouched. I started with 103, and bumped it up to 105. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. 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). I have briefly thought about pre-infusion but the REX C-100 is not capable of this. This resulted in the PID not powering up even though the machine did. Power input. I am glad this article helped. PWM dimmer for preinfusion Final note: before going down the PID route, the easiest modification to make, and the best starting point for Gaggia Classic modifications, is lowering the brew pressure. Your email address will not be published. Looking forward getting your thoughts and ideas But, I still get loads of steam and spray before it settles down. The Auber kit looks easy since I dont have time to build my own. The installation is completely reversible if you ever want to sell the machine or send it to service. 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 . It is suitable for other colored espresso machines. I would like to use it for steaming ONLY. Feel free to hang out, learn a bit, meditate, ride a bike, or perhaps it's just time to move on. Its one more thing to plug in, but the upside is that it would be electrically isolated from the Gaggia. I found this M8 female to M4 male reducer: https://www.ebay.com/itm/284317077676. August 05, 2019, 11:46:38 PM . Chris, this is a far simpler way to add preinfusion. After the kit is installed, the standby brew watertemperaturecan be controlled to within 1 (F or C) accuracy. 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). To be clear, a PID can increases the likelihood of a consistent starting temperature. I just finished installing the PID hardware in my Classic Pro today. You should be able to find the switched mains with the help of a multimeter. 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. Thanks. What you do get from the PID as per this guide in steam mode is the ability to see exactly what the temperature of the boiler is, so you can time your steaming to start during a heating cycle, which essentially gives you unlimited steam. 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. See all. I want to get a PID for my GC. If so, any idea how it can be achieved? I actually ended up getting the one you recommended. sv4mzu 20, 2022 8:05 am. See our 325 reviews on. 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). Thats an awesome enclosure. 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? Heres how to install a PID on the Gaggia Classic Pro. I have few questions for you about this setup. The sensor has three wires: 1 x red and 2 x white. Using pliers to pull the connectors can pinch them on even more tightly, making them extremely difficult to remove. Box color. Adding pre-infusion would require either a different and significantly more sophisticated PID, or integration with something like a microcontroller. This prevents the high-pressure water from contacting the dry coffee powder which can create afast flow channel, ruiningthe brewing process. Log in or sign up to leave a comment. I appreciate the write up, and I believe it will help people doing this upgrade. I will purchase the PID kit with thermocouple and SSR from aliexpress and buy these rest small items from Mr. brew thermostate. Hi Gene. The little red collar shows the location. To set the target temperature, press the Set button on the front of the panel. (The Gaggia machine is not included in this listing). The default target temperature on the PID will almost certainly not be correct. You could simulate pre infusion by briefly running the pump. These set the parameters and algorithms that monitor and control. I have not changed any of the P, I or D settings on my controller. Thanks! I'd like to increase the brew temp a couple of degrees but have no idea how to do this. Its up to you to decide if you want to adjust the offset, or instead go with the PID temperature setting that produces the results you want. Auto-tuning PID cooling/heating control 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. The pump is not wired in series with the Heating element so Im not sure what is causing this. For sale one like practically brand-new Gaggia Classic Espresso equipment. This PID controller kit has all the features of our other listing titled "PID temperature control kit for PID Retrofit KIT for Gaggia Classic & Home, KIT-GG", with the addition of pre-infusion and steam temperature control. Hi Brian. You can mod the XMT7100 yourself but it requires soldering on the PCB, basically removing the onboard relay and then jumpering the empty terminals. This is probably the most difficult part of the installation. I also checked to ensure that the physical steam switch is functioning correctly and the circuit is broken when it is off. 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. For those interested I just bought a cheap ($13) K-type thermocouple and thermometer (TM-902C) https://www.ebay.com.au/itm/224710871179. It is still showing the M4 screw as the Crossed out/wrong one, and can be a bit confusing. ). $149.99 . Do you observe the same temperature ranges? Did you try it? Looks like thats not an option. 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. For more than half a century, Gaggia has been supplying both coffee bars and homes with innovative, state-of-the-art coffee machines. Nevertheless, it will take some time to get it and make a change of the temperature sensor. 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. Like NEW Gaggia Classic Espresso w/ Grinder and Base - - 6758821731. When the temperature stabilizes to within 1 degree of the target temperature, the auto-tuning is complete. Instruction Manual: The instruction manual & installation documents areonly available for download for customers who already purchased the kit. Thanks. The solution is PID control via means of an industrial temperature controller; this is a common modification amongst the Gaggia and Rancillio community. The PID itself draws very little current, so something like 18 gauge lamp cord would work.
