Chris, i read some comments here about steam. The connector is on the back of the machine, where mains power is tapped with a piggyback connector and goes to the PID. When the steam switch is turned on, the on/off temperature of the heater is controlled to 1 degree (F or C) difference as compared with the original thermostat's >10C (or 20F) difference. 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. 2. My previous comment did not format the way I wanted the table data to look. Home; Search; Log in; Sign up; Updates: Click here to visit our store! Auber Instruments PID Kit for Gaggia Classic quantity. The operation is the same as the unmodified Gaggia machine. This morning I pulled my first shot with the PID. Ive noticed that the PIDs output1 LED isnt illuminated after it climbs above my set temperature (103) but the boiler is getting heated up regardless. 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/. LED display color. Nikola. Zip ties, heat shrink tubing, thermal paste, double sided tape, and a bolt and nut to attach the SSR are also required. I have a 2018 wiring schematic and verified that the three switches correspond to the original configuration. I have an old Gaggia Carezza (uses the Gaggia / SaecoEF0030/A Boiler). European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Brilliant article. When the pump runs, it vibrates the chassis and it will be a matter of time before it cuts through the wiring insulation. I did not use a grommet. You would probably blow the fuse in this controller/SSR within seconds. Hi Chris, I went with an insulated PT100. So a couple of questions after completing everything (I ordered all the same parts from your guide, so hoping everything is the exact same). If you had to recommend a single display PID, which one would you steer me to? One bit of note and a request. 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). Then use the left/right buttons to select the digits to increase and decrease, and the up/down buttons to change the digits. Net Weight: about 150g Its pretty straightforward. Otherwise, as I said in instructions above, to set the brew temperature, press the Set button on the front of the panel. I am now waiting for my PID unit and thermocouple with M4 head to arrive this week. Your Gaggia would be in steam mode by default, you would never have to switch on steam mode. After the kit is installed, the standby brew watertemperaturecan be controlled to within 1 (F or C) accuracy. Do you observe the same temperature ranges? 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. I have few questions for you about this setup. Or buy a machine with a built-in PID. Hi Chris, I also checked to ensure that the physical steam switch is functioning correctly and the circuit is broken when it is off. Have you written an article regarding installing a Gaggiuino mod? Thus, it will significantly improve the taste and consistency of your espresso. It can be installed on Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espressomachines. 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. Hi Brian. if i understood not adding a steam will give better steam? Do not undertake this procedure if you are not comfortable or uncertain. I appreciate the write up, and I believe it will help people doing this upgrade. Hi Chris, Ive followed these instructions exactly (thank you for your thoroughness) except for how the mains were tapped: I moved the two wires terminating on the bottom of the power switch to the top, and tapped them (as per another guide). D 9. 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. Maybe Im missing something? I was like WTF. Is there a way to tap into +/- 12Volts inside the GCP? 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. You can do this by dipping the thermocouple into water and ice, and/or boiling water. This video clearly shows how to program in an offset on the Rex C-100: https://youtu.be/9aW8MfiKIPg?t=291. Neutral is the return path for the hot or load wire. Approach 2: Divert from my writeup by installing the thermocouple so that it replaces the steam thermostat, and set the PID temperature to your preferred steam temperature. Each segmentcan be set by the user with 0.1 seconds resolution. My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). The most I can say is these work for me, and are probably not optimum. 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. Gaggia Classic Coffee Machine Modelo 3D TurboSquid 1036412. Perfect, came back here to ask this question! Hi Eddie. The best part is I am only in about $40 on my kit compared to around $150 for the pre made kits. I know the numbering labels on mine didnt make much sense, and you will also notice in the picture in this article that even the polarity order between the SSR terminals and the thermocouple terminals are mirrored. Nevertheless, I will take a look and see what values my controller is set to. 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. Hi Chris, I am gathering / ordering the parts specified and was surprised to find out the price for 3d printing price spiked. the PWM needs a new wire to the where the pump wire was disconnected. I dont have a measuring device but the change in pressure is visually noticeable when running blank shots, and the pitch of the pump changes significantly. 102 is even 3 degrees below my brew temperature. share. That is confusing. Please see the compatible model list below (Note 1 on the bottom). 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. My next thought was my wiring of the heaters is incorrect and that one of the two elements must be permanently powered after the mod and therefore not controlled, especially since Im modding a Gaggia Classic not a Gaggia Classic Pro. This prevents the high-pressure water from contacting the dry coffee powder which can create afast flow channel, ruiningthe brewing process. Never used a K type so I cant say for sure. But I would definitely read the instructions that come with whatever you receive! 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. I strongly suggest checking which switch terminal switches the mains.
