Tune P/I terms to maintain consistent boiler housing temperature once the initial drop has been halted/reversed. As an aside, a great way to tell when you've properly primed the boiler on the Classic is to, with a PF locked in, run the pump until the water stops for a second then kicks back in. Gaggia Classic is available in a stainless steel finish, No other Colours, No other finishes, Its a Classic Review of the Gaggia Classic 2019 by Rob Armes Classic Review by Coffeeblog.co.uk Listen to and watch what Todd Salzman from Wholelattelove says..

If you find the temperature is climbing or dropping during a shot or over the course of a few shots, I'd suggest decreasing/increasing the OPH variable by one percent at a time. If you'll be making milk-based drinks the PID is a total game changer when it comes to steam power. 2. It could be wired to use the Gaggia's stock brew switch to run the PID/timer, but I wanted to leave it as a manual brew switch for the others who want to use the machine they way they are used to using it. I don't have a PID installed. User account menu. Espresso PID Controller. /r/ Coffee is a place to discuss any and all things coffee. The slow responding and somewhat innacturate bimetal coffee thermostat is replaced with a K type thermocouple connected to an Arduino controller that controls a Solid State Relay (SSR) to control power to the small boiler inside the espresso machine.

Here below the easy instructions to follow: 1. Well it has arrived and it only took a week from the US. Mounting the thermocouple to provide minimal response lag is essential. Control the boiler housing to such a temperature that water flowing through and mixing in it at the usual flowrate (for a double espresso) is heated to the desired brew temperature. Gotcha. (Pseudo-HX Configuration) (Pseudo-HX Configuration) The how and why are a bit long, so for anyone just reading casually stick to the bold; the Gaggia Classic has very poor intra-shot temperature stability, but it can be brought to ~2C relatively cheaply. This takes the guesswork and water waste out of flushing. I drilled through the centre of an M4 brass standoff like this, then inserted the bead/braid through the hole so that the bead was poking out the threaded end by a few mm. Feel like price for features of the modded gaggia was a win.

Discover the magic of the internet at Imgur, a community powered entertainment destination. I wasn't perfectly scientific in my measurements/tuning and am aware of that, but I suspect this is the cheapest way of getting a quality, reasonably temperature-stable setup, as Classics can be had in good used condition for 150-250AUD and the full PID setup is another 50AUD. Gaggia Classic Pro after modifications. It will probably take you most of a day to install them. Because both the stock thermostat/TC mount and the boiler intake are at the bottom of the boiler, and the boiler discharge is at the top, the thermocouple is able to react and start heating the boiler before brew water temperature is negatively impacted. The other "gotcha" is that despite a background in controls and automation, the tuning was trial and error to a large extent, and it took me probably six hours and 1.5lb of beans before I was happy with it.

The Gaggia Classic, a solid single-boiler will stand the test of time with an enduring brushed Stainless Steel casing. This was measured with a bare TC bead sunk just far enough into the puck so as to avoid touching the shower-screen. They won't be perfect for everyone but they should be a good starting point.

I didn't realise how bad as I never measured it properly, but in the following link it is noted as showing a 7-10C drop over the course of a 60ml pour. Press the And IMO, pre-infusion, temp profiling and pressure/flow profiling tastes noticeably better and provides consistency. That said, I've done most of the hard work and the PID settings should be reasonably consistent between machines, assuming the thermocouple is installed "correctly". 1. Fitting the A separate page about my research interests.

The instructions come as a set of PDF's and seem to be very comprehensive. By doing this, the TC bead is pressed against the boiler housing at the point closest to the boiler water, and is assisted by the thermal transfer compound. Relatively easy instalation with the instruction they provide. Both are good mods, and well worth doing as long as you're comfortable digging around in the guts of the machine. After all this, I found that with the PID setpoint set at 94C, the brew temperature would rise to 94.5 and fall to 92.5 minimum. I figure Im gonna have this machine for at least a few years, so might as well get it out the way. I find that unless I purge, wait for the temperature to drop a bit and then start steaming when it's on the rise, it drops too low and doesn't recover enough temperature/steam power before the milk is up to temperature. 4. I installed the OPV mod and PID from mr. Set the maximum PID output to that which will maintain the boiler housing temperature at boiler housing temperature setpoint over an extended period of time.
