Hi Jeff. 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. The rich body and complex flavor profile of a well-made shot brings the beans to life with a depth that other brewing methods fail to achieve. I went with an insulated PT100. Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. 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. Then use the cursor keys to select the digits to increase and decrease. Obviously the actual water temp will be different, but I can use this range to try and get a consistent temp when I pull a shot. What you describe looks very much like the steam thermostat cycle. Hi Gene. And once you start considering adding in a power supply, you might as well go for a PID. You can buy them at Ace hardware for about twenty five cents each. If you need to replace the PID controller, please contact us. https://www.auberins.com. 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. Maybe this could serve instead of trying to find an M4 thermocouple. The pump is not wired in series with the Heating element so Im not sure what is causing this. I am guessing that its caused by the current draw of the boiler heater. The fun of the PID is not just the great stability, but the ability to fine tune the brew temperature to your taste! Maybe this will help? Tap the neutral mains: disconnect the lower wire from the mains connector at the back of the Classic. Depending on the enclosure, you may need to insert the PID into the housing first. I think Mr Shades has managed to do this using only cables because I dont think he instructs anything to void the warranty. Auber Instruments PID Kit for Gaggia Classic. share. Most guides recommend connecting the SSR to the Gaggias (metal) body with some thermal paste, and this mount then serves as a heat sink. 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. Their kit is convenient, and is the way to go if someone doesnt feel ready to take on a 100% DIY project. (I am not testifying to the quality of the shots!

Looking forward getting your thoughts and ideas This steam blipping is a fairly common practice that people use to avoid boiler heater cycling, its just another way to do temperature surfing. Use the other probe to check the other two wires coming from the power socket. I had no issues with the K type thermocouple. If your connection is down to just a few strands, that will generate heat. Heres how to install a PID on the Gaggia Classic Pro. I used the same controller ( XMT 7100 ) which Mr Shades is selling. You could approach this two ways. We ship every business day from our two warehouses located in Milton, Ontario and . How to install a pid on the gaggia classic pro. The C100 is probably made by dozens of different manufacturers. This would also allow you to switch to PID-controlled brew mode simply by lowering the PID temperature. I am not surprised that the steam kit made little difference. Any ideas? $285.00. Hi Dennis. This process involves working with potentially lethal mains-level voltages. excluding VAT. I love the Lego enclosure idea. and I didnt work straight through, but I would say the PID took me about 2 hours, not counting the down time due to the crossed power wires. 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. The kit installation is fully reversible. 1. . I opted to follow my connections according to your picture, rather than that text.

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? After the kit is installed, the standby brew watertemperaturecan be controlled to within 1 (F or C) accuracy. P, I, d, controlling period, digital filter coefficient, and more (for control theory experts only) 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. Pull the steam wand up and out of the Classic, and set it aside. Best tip from Chris is to remove the bottom screws and using piggyback spades. Leave this cable longer than needed for now, it will be trimmed and terminated later. When I say old, it is still unused new in the box. Shall I connect it to terminal 5 or 2 of the on-off switch? Allow easy adjustment on the coffee water temperature. Your wiring looks right. It really pays off to assume nothing, and test everything.

You would probably blow the fuse in this controller/SSR within seconds. Thank you for making it. I actually installed mine and then saw your thread, which is awesome to see other people using the same PID. Previous topic - Next topic. Hi Chris, The PID unit did not turn on using the same terminal of your machine. 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. That being said, the original brew thermostat is supposed to be 107C, so could perhaps reach even higher temperatures? 3. One bit of note and a request. Where did you place the SSR? Regarding the M4 screw/ thermocouple, is it possible to amend the picture? 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). 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. With a PID controller added to the heater control circuit, brew water temperature can be controlled to within 1 accuracy. The PID itself draws very little current, so something like 18 gauge lamp cord would work. 4.8. Hi Justin. Hello Chris, Hope this helps. However with the new steaming alarm system, I get a decrease around 10 degrees in steaming temperature as soon as AA SSR shuts down the boiler at the temperature I set, even it turns on right away (my setting is AL:156 AH:155 degrees Celcius). Monitor and display the boiler temperature precisely. I was like WTF. Or do you think the same set will work with QB-T7100? Plug in a mains-rated cable connected to a piggyback spade connector, and then plug the original switched mains cable into the piggyback. It would also be a bit of a weird machine, but this approach wouldnt require any mods or re-setting of temperatures to use the machine to brew. Im tempted to return the GC because I never used it prior to the mod and it may have been a pre-existing issue. Because the PID runs on mains voltages, an enclosure is required. Hi Brian. The Gaggia Classic is a very capable espresso machine that gets even better with a couple of improvements. Hi Ray. Stay connected. Apart from that, when I turn on steam mode, the thermostat takes temperature in the machine around 151c-152c, it doesnt turn on again after it goes down to 102C, then turns on and repeats the cycle. Should this be cause for concern, maybe caused by an error in wiring the PID? The digital LED display module is available in red or white. Accuracy: 0.2% 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.
