However, depending on the seller, some settings may need to be changed. If not, can you think of any potential mistakes I made along the way? Note: I fully tested the PID, SSR and thermocouple on the workbench before final installation. Apologies for the long questions, thanks in advance! You can take a look at this discussion about offset in the Gaggia Classic: https://coffeeforums.co.uk/topic/53319-what-temp-offset-are-you-using-with-your-pid/. 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). But this kit doesn't fit the European model RI9403, which has a stainless steel boiler with a different thermostat mounting. 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 have found the exact PID unit which Mr Shades is using and purchased it beside the Rex C100 kit you mentioned above: 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? Heat the shrink tubing. You are right, its an M4 thread, not M3. 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. This gives the machine a whole new level of consistency, and gives you fine control over brew temperature. The preinfusion thing is a bit ridiculous, it just turns your pump on, off and on again. Hi Chris Is there a way to calibrate the read out close to the water out temperature. To set the target temperature, press the 'Set' button on the front of the panel. On top of the original price tag, international shipping, taxes, duties and currency exchanges can make obtaining these kits time consuming and even more expensive. Disconnect the two connectors from the brew thermostat, which is located on the bottom left-hand side of the boiler as you face the machine. I guess I could revert the machine and see what I get. The taste of a real Italian espresso everyday! Hi Andrue. Hi David. You could approach this two ways. Note that my mod is to a Gaggia Classic, not a Gaggia Classic Pro. The kit includes all the parts and the materials to complete its function. Thoughts & musings from a product developer and manager. So I would say yes, you should use a heat sink, but the Gaggia body conveniently provides you with that function. If you really want to avoid the heating element switching while youre pulling a shot, you can blip the steam switch for a few seconds before brewing and that will bring the boiler temperature up a few degrees. Chris, i read some comments here about steam. Thank you Chris for the awesome write up. Its pretty straightforward. 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. KIT-GG Installation Guide Version 1.3 Auber Instruments, 730 Culworth Manor, Alpharetta, GA 30022 e-mail: [email protected] Tel: 770-569-8420 www.auberins.com . Is this just a matter of adjusting the offset of the PID? Its not hard if you know what you are doing and there is at least one youtube vid showing how its done. Warning! Please check KIT-GGX-EUinstead. If the wiring in your machine is different from our installation guide, please contact us. Because the wiring connections can vary between manufacturers, you should bench-test your setup before final assembly. For more than half a century, Gaggia has been supplying both coffee bars and homes with innovative, state-of-the-art coffee machines. Do you have any idea how to do? It doesnt matter which mains terminal is connected to hot and which one is connected to neutral. 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. Please see the compatible model list below (Note 1 on the bottom). The pump is not wired in series with the Heating element so Im not sure what is causing this. 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 have changed the default value of the SL parameter to work with the RTD sensor (K thermocouple was default). If you want to defeat that auto-power-off feature, please add this piece of wire to your order. All other variables aside, once you get a temperature that gives you the results you want, you will be able to get those results again, and again. Or do you think the same set will work with QB-T7100? Thanks in advance, this was a huge help! I think this is why using a separate SSR and controller is the only way to go. 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 deliberately avoided looking at the Mr Shades kits and instructions when I wrote this article, I dont want to steer people away from them. The pre-infusion timer can also be used as a countdown shot timer. I decided that for me, its not worth worrying about. But I would definitely read the instructions that come with whatever you receive! Was hoping to actually just install one of these: https://www.ebay.com.au/itm/264849127538 Thanks for the info, D. Your experience further goes to show that there is no standardized wire color coding in the GCP, even though black is usually hot and white is neutral. Universal Input: Thermo Resistor: PT100, Cu50 . The steam mode drops to 102 before the power cycle kicks back in, with the valve open or closed. In a nutshell, the Gaggia Classic thermostat is replaced by the combination of the the thermocouple, the PID, and the solid state relay. Hi Jeff. Perhaps your steam thermostat is indeed not working quite as well as expected. Regulate the standby coffee water temperatureto within 1 (F or C) accuracy. I grabbed some screws from my parts bin, I took whatever I could find that was the same color as my filament, and that would fit the holes and hold reasonably well. It would be great to see how the machine is behaving without the PID, to get a baseline. Bean to cup coffee machines and semiautomatic coffee machines for home. $375.00. If you have the regular version (RI9380 120V, or 240V), you DO NOT need this wire. Im all for freedom of expression and creativity, but not when it might electrocute someone. Be careful, the edges of the hole in the chassis are very sharp. Hi Murat. different wiring though. Im sorry about that, Eric. Most likely they will have the same connector types as the REX-C100, but its always possible that you will need different connectors depending on what you end up ordering. Thus brewing circuit needs to be connected directly to the heating element, not over steaming circuit. 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 installed the PID so that there are no permanent modifications to the machine, and the Gaggia can be returned to factory condition at any time. However, at the cost of convenience, these kits can be relatively expensive. Well I ordered the wrong thread. 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. Hi Dennis. The default target temperature on the PID will almost certainly not be correct. Useful Video. 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). Locked Topic Sticky Topic . I still have one question you may be able to answer. See here for details. Popular categories from this store. Does this happen even if you let the machine sit in steam mode and dont open the steam valve?. Auber Instruments PID Kit for Gaggia Classic. If you want to defeat this feature, please add this optionto your order. 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. Thanks. The only cable arrangement I had to change after installing the PID was switching those cables in the back, the one on the top I had to put in the bottom, and the one on the bottom in the top, otherwise the PID would stay on when the machine was off, and off when the machine was on. However, when I flip the gaggia power switch to off, the PID LCD screen remains illuminated. This is the setup that I have assembled two days ago. At the amperages required to control the boiler heating element, you need an SSR that has enough mass and exposed metal to be able to attach it to a heat sink. The silver box is coated with clear anodized aluminum with a brush-finished stainless steel front panel. Many thanks for such a comprehensive write up of your project. 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? Looks like thats not an option. Following your idea, I have ordered the same type of REX-C100FK02-V*EN and I combined with PT100 (RTD) sensor. Specifications : The Auber pretends to add a couple of things, but functionally, they're very much the same. 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. Started by Rocky47. This product was added to our catalog on Tuesday 26 June, 2007. (For orders placed recently in 2022) If you placed the order as a guest, you cantry the, (For orders placed a while ago) Please log in and download the manual from your order history page. These are located around the shower screen. Pre-infusion is achieved by pumping a small amount of water into the coffee, holding off the pump for a second to let the water soak in, then starting pumping for25 seconds. Because the PID runs on mains voltages, an enclosure is required. Or is the only power available from the mains? Hi Justin. Then use the left/right buttons to select the digits to increase and decrease, and the up/down buttons to change the digits. Fast, Free Shipping. I have to turn the set point on the PID down to about 85C to stop it boiling and getting steam and a great deal of sputter out of the portafilter. 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. 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. Hi Jun, and thanks for the update. 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. This resulted in the PID not powering up even though the machine did. Applications When set up on my bench it tucks away nicely in behind out of sight and only needs to come out when in use. Feel free to hang out, learn a bit, meditate, ride a bike, or perhaps it's just time to move on. PID Control Kit for Rancilio Silvia Espresso Machine, White LED $164.99. Please contact us if any questions. LED display color. I dont own a multimeter. Note that according to this video: https://www.youtube.com/watch?v=UETVv0qgz-w, you can switch the C-100 between Celsius and Fahrenheit. 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! http://facebook.com/HKCoffeeHome EspressoGaggia Classic !Gaggia Classic can give a good espresso shot . Somebody else (Andrue) had also pointed this error out. Have you noticed any problem using REX-C100FK02 and RTD PT100? It will void your warranty, the possibility for making errors or breaking things during installation is too high, and the amount of time it takes would make it cost prohibitive. What is your coffee bean dark or light? Instruction Manual: The instruction manual & installation documents areonly available for download for customers who already purchased the kit. Again, as above, run this cable out the back, and leave it unterminated and longer than needed. Theres also a M4 connected thermocouple wire on Amazon that arrived fast although it increased the whole cost compared to Bangood. 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. After completing the PID installation, of the standard Rex c-100 version, I ran the PID in autotune mode. Locked Topic . Thank you for your time. It should be placed as close to the left-hand side of the Classic as possible. Chris thank you so much. 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? Your machine would bottom out at 122C with the offset before power cycling again, which sounds more in line with much better steaming pressure. Visit store Contact. When I turn off, it goes back to zero. Two different colors of the controller box are offered, silver and black. This approach would make your machine a bit weird to someone who wasnt aware of what you did, as the brew function would be completely unusable without adjusting the temperature. With this tight temperature control, you do not have to surf the temperature for frothing because the heater will kick on much sooner than the original thermostat. I have re-read the specifications for this controller. New - Gaggia Classic Pro/2019 PID kit - 1/32DIN single display. Hi Gene. Some shops are quoting $80.00 for the PID enclosure + lid.
