However, there are examples on the internet that implement steam control using PID as well, the main purpose to increase temperature a bit (within a safe range) to achieve higher steam pressure. Learn, shout, complements.Keep in touch with us on social media. $209.99. Thanks for your answer!Somebody told me that my pid is not ok for this project because it has "VOLTAGE" output as you can see the picture(http://www.kephost.com/image/F2Fj), not "RELAY" or "SSR" output. What is the full spec? There's no doubt going blind leaves me with shots that go from fantastic to 'meh'. You inspired me and I'm going to PID my Gaggia! The terminals you have used are 4,8 or 6,3 mm?

Please contact us for more information. The basic idea is to make SSR acting as former bi-metal thermostat (turn on and off the heating element), so both cables that were connected to thermostat (white on my picture) go directly to SSR terminals 1 and 2. Could you please tell me will this work for GranGaggia (RI8323/08)? I finished the wiring, but something is not OK.

It''s a good setup. Hello, terminals are 6.3mm, cables are normal, but thick enough. For example, the guy on this video https://www.youtube.com/watch?v=2NpcMycHDvk is modifying "relay" version to make it work with SSR (beasically he converts rex-c100fk02-M into rex-c100fk02-V, the one you already have). Powered by. This gives the machine a whole new level of consistency, and gives you fine control over … I'll probably end up with a Classic eventually - the Evolution is incredible, but it lacks the 3-way valve - so I'm usually left with a sloppy mess of water if I use fresh grounds. Or i can use any of those cables to attach my cables from ssr? Your mileage may vary. Another thing you need to reach, is to power up PID when coffee machine is ON. The reason PV (measured value) goes above SV (set value) it probably because control pulses are too long, so the latest pulse (that makes SSR "on") before it reached set temperature, make the boiler hotter than set temperature, then it stops pulsing (because set temperature is reached) and waiting till it goes down below set temperature, and then starts pulsing again. Thanks for your answer!First i would like to "mimic" your job. I never use the funnel, which is located underneath the flap on the top and feeds into the tank at the bottom; I always fill the machine from using the tank directly. 67 sold. The boiler one is down on the side, and I had removed the steam one by accident, which is the one on top with the red dot. Adding a DIY PID to the Gaggia Classic Pro. My way was much cheaper, is designed with features I wanted, but is definitely a lot more complex. Before starting autotuning, make sure that boiler is hot (reached the set temperature), and do not start shot pulling during autotuning, just wait till it completed and check that p i d values have been updated.Do not worry about flashing LED, it is barely an indicator that SSR is triggered (powered on by PID), it is not that smart to indicate about failures :)). I have ordered PID, SSR and temperature sensor but I need to buy necessary terminals (piggy back etc). Have to say it makes a huge difference for me. Edit: I am 100% self taught though, (though I have an engineering background, it's chemical). Temperature (in Fahrenheit) is shown on Y axis and time is on X axis. 1 Replies 2400 Views Sharron September 08, 2016, 02:45:15 PM Operation Manual for Auber PID controller. Thanks!

The remaining part of post describes my own experience of equipping Gaggia Classic coffee machine with PID controller. Hi FA, connection to PID (your pictures) seems OK to me. The kit from auber looks very easy, very plug and play. I was wondering if these kits alleviated some of the problems. If you find temperature resistant one that will be better of course, but the temperature of the boiler when it is hot is not sufficient to melt the "normal" cable housing in fact. If SSR did not work, the boiler would not getting hot. Many thanks for excellent photos and explanations - something I want to after I combined two machines into one to make a twin boiler machine. And yes have adjusted the pressure to 9 bar. Since I do not have an electrical engineering background, I have ordered from Auber the complete kit (which has arrived through FedEx this morning), now all I need to do is install. Is the idea just that the steam temperature control is good enough and you don't want to deal with having to readjust the PID for steam each time? Previous model RI9303 is also compatible. The ability to make good espresso is one of the most coveted skills in the coffee world. Can you please send us a link so we can find your rtd sensor?
