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. You should see a strange number when the PID first powers on, then after about 3-5 seconds it should switch to the temperature reading from the thermocouple. Then I realized that EU models come not with a bistable rocker switch but a momentary one (so electricity flows only when you actively pushing the button). 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? Allow easy adjustment on the coffee water temperature. The PID kit you described should work, but like the C-100 kit the I used, the included thermocouple wont fit in the Gaggia Classic. This is not a difficult mod. Two different colors of the controller box are offered, silver and black. 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. As for you steam mode question, if you followed this guide for installing your PID, the PID will have no effect on the the steam temperatures or functions. If the thermocouple wire is too long, coil it up inside the machine, well away from the boiler or any uninsulated connections, using zip ties to hold the coil in place. The kit includes all the parts and the materials to complete its function. Visit store Contact. Net Weight: about 150g 100% Positive Feedback. Thanks Jimmy. After autotuning, my values are: When the ">" key is pressed, the controller starts the brewing sequence automatically. The installation is completely reversible if you ever want to sell the machine or send it to service. The SSR is only rated for 5 amps. So this suggests that the machine is getting much hotter and I reduced the the set point to 95deg from your recommendation of 103degC. One last question: Auber and Mr Shades are calling their sensors PT100 while mine is K type thermocouple. And this is the thermometer out the back. Approach 1: Follow my writeup, adapting it to your models peculiarities, and then set the PID temperature to your preferred steam temperature. That would be easy enough to verify with a multimeter, to see which thermostat is active in steam mode and which one is active in brew mode. Let me know your thoughts !!! The result was overshoot of up to 18C and an inability to return to the setpoint temp, 105C, unless I shut everything off and restarted. Spent some time playing with temps and pulling a lot of shots to dial it in and am very happy with the results. If so, any idea how it can be achieved? Warning! The operation is the same as the unmodified Gaggia machine. Greatly improved the taste and the consistency of brewed espresso shot. 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. Not really preinfusion, just an excellent way to crack the puck before your shot starts. Have you noticed any problem using REX-C100FK02 and RTD PT100? 3 months later, Ive finally set up the PID and honestly, its a gamechanger! As the optimal brewing temperature is 90C to 96C depending on taste, this variance means the coffee can be over or under-extracted, or worse - variable. Please contact us if any questions. Hi Chris, I appreciate your tutorials on the PID install. Mains is house current. The factory settings have been working well for me, aside from a ~5 degree C overshoot when it first reaches the target temperature. It also means that you can only see the temperature and access the PID buttons from the top. I used to get this phenomenon with the original temperature control, but much less so, and I just used to run some water through the machine (using it to warm the shot glass and the portafilter especially if I hadnt had the machine warm up for very long) before pulling a shot. Measured everything with multimeter, then realized that C100 doesnt get main while machine is on based on the lights. Mounting Dimension: DIN: 1/16 (48mmX48mmX80mm) The C100 steps down mains voltage to 12v to power the SSR. European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Or do you think the same set will work with QB-T7100? I still have one question you may be able to answer. I think Mr Shades has managed to do this using only cables because I dont think he instructs anything to void the warranty. Its not hard if you know what you are doing and there is at least one youtube vid showing how its done.

Thanks Alex! With a SV of 103C (not offset), during initial overshoot the heater would sometimes be one when it was at 104-105C with the temperature rising as high as 108. Note that my mod is to a Gaggia Classic, not a Gaggia Classic Pro. This resulted in the PID not powering up even though the machine did. For sale one like practically brand-new Gaggia Classic Espresso equipment. A cheap multimeter is all you need. For the Classic Pro, this requires either shortening the spring in the OPV valve through trial and error, or ordering a spring kit from Mr. Tighten one end of your connector down to one of the solid state relays AC (~) terminals and plug the other end into one of the disconnected thermostat wires. Some people have done this by replacing the water filler funnel and 3D printing a replacement cover. Plug in a mains-rated wire connected to a piggyback spade connector, and then plug the original neutral cable into the piggyback. excluding VAT. The steam mode drops to 102 before the power cycle kicks back in, with the valve open or closed. Guys, there is mains voltage here. 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. Then use the cursor keys to select the digits to increase and decrease. 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. Always work with the Classic unplugged. If you want to defeat this feature, please add this optionto your order. Same with the adapter screw. 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. Thermocouple included: M6*1 thread , K type , 2m cable The connector is on the back of the machine, where mains power is tapped with a piggyback connector and goes to the PID. However, at the cost of convenience, these kits can be relatively expensive. 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. The Gaggia Classic is a very capable espresso machine that gets even better with a couple of improvements. Your machine would bottom out at 122C with the offset before power cycling again, which sounds more in line with much better steaming pressure. I stumbled onto this before I actually had my Gaggia in hand and went about ordering all the parts. I am now waiting for my PID unit and thermocouple with M4 head to arrive this week. Unfortunately, no, you cant use the factory sensor. Have had the parts sitting around for months and no time to install! $375.00. Pull the steam wand up and out of the Classic, and set it aside. I got the white plastic in one of the stock connectors a bit burned, the plastic looks brown in some areas and a bit melted. Whole Latte Love has a new video about preinfusion on the classic.

I also checked to ensure that the physical steam switch is functioning correctly and the circuit is broken when it is off. It really pays off to assume nothing, and test everything. Or buy a machine with a built-in PID. Hello, Sure enough, it powered up. CONCLUSION! Hi Murat. Thanks. Im thinking Id like to start with just a temperature indicator, to assist with the surfing. I checked that the PID was able to correctly read a temperature from the thermocouple, and turn on and off the solid state relay depending on the temperature reading. I tested the current with multimeter and it is showing DC 100V when I turn on the on-off switch. Remove the cover assembly and filler funnel by unscrewing the two small screws at the rear of the top.

I have to mention that coffee taste is good, not harsh or bitter. I havent lowered brew pressure to 9 Bars yet so perhaps changing that would level out my pump pressures? Previous topic - Next topic. I bought the same parts as you have reccomended in the article but have run into the issue that the thermocouple is too large to fit into the adapter (theyre approx the same OD). Hello, I acquired and prepared all cables and SSR unit thanks to your well prepared title above. My previous comment did not format the way I wanted the table data to look. There are several PID kits that are available for the Gaggia, the most popular ones are by Mr. Some shops are quoting $80.00 for the PID enclosure + lid. For the sake of piece of mind, I have ordered last night a K type thermocouple in order to replace the RTD P100 and close the open loop in my head about PID type and sensor. Thanks.

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. Hi Miguel. I actually installed mine and then saw your thread, which is awesome to see other people using the same PID. I then thought what if? and decided to change the mains wires to the opposite terminals. Chris, this is a far simpler way to add preinfusion. I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. I dont bother with offset, once I have a temperature dialed in, it doesnt matter whether its measured at the boiler or offset for the group head. Any ideas? My P value is quite a lot different than yours. If you have questions regarding ourcoffee kits, please check ourHelp Centerfirst. Hi Gene. Auto-tuning PID cooling/heating control They have no effect on the temperature during a shot since the heating element cannot respond quickly and accurately enough to manage intrashot temperature control. 0. I also think that you may have less difficulty reaching the thermostat, the 2019+ models have a lot less room to spare inside. I cant see why you couldnt.
