If you really want to avoid the heating element switching while youre pulling a shot, you can blip the steam switch for a few seconds before brewing and that will bring the boiler temperature up a few degrees. 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. If you have never done this before, know that you are working with live household current, and this can kill you.

You effectively would have two steam modes, one PID-controlled that replaces the brew mode, and one classic thermostat-controlled steam mode. Hi Paul. From what I have read, the PID with the additional steam mode option does not improve things much. New to the forums, but I've been experimenting with espresso at home over the last year when my brother gifted me a used Gaggia Classic with an Auber PID. Thanks.

It has a blue led not red like pictured.The kit works for 115 VAC and 240VAC. The steam mode has its own thermostat, which is very similar to the brew thermostat that the PID replaced, except that its temperature range is more or less as you described. I have only been drinking milk drinks and americanos because the shots I was pulling were always overly bitter, sour, or both, regardless of grind and quantity. 3-Connect the other cable to the terminal on the on off switch, which is on top of or below the Live cable. The SSR is only rated for 5 amps. 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. I cant see how this wouldnt be a thermostat problem, unless you somehow wired the steam thermostat into the PID, but you would have gone way beyond this walkthrough to do that. The PID I ordered came as a package with a solid state relay and a thermocouple, but that thermocouple had too big a diameter to with the Gaggia. But will there be an upper limit to prevent the boiler from going near 365F and blowing thermal. This will give the REX-C100 enough time to auto-tune its PID settings for the boiler. This is sold on amazon Shop for it now! If you are in the U.S. then mains voltage is 120V, which will not kill you (unless you have a pacemaker or are standing in a bathtub) but can give you a decent shock. Nikola. Also noticed if you use the steam for the milk it takes a lot of time to go back down (10min) to the set temp(i do run water through the boiler to bring the temp down, but it floats at a higher temp for a bit), does the steam affect the PID calculation or dont I need to worry about it? Run-program does a 1s pre-infuse followed by about 1s pause, then 30s pump on. If you really want these features, its probably time to think about upgrading your machine. Run this wire along the rest of the existing cables and out the back of the Classic, through one of the vent slots. 0. My question is where did you place the SSR, is it near the water spout, right side or in the back if you are facing the front of the machine? The only suprise for me has been that installing steam kit did not help me much because brewing kit alone helped to have great steaming power by only watching temperature climb up to 150 degrees. Most likely they will have the same connector types as the REX-C100, but its always possible that you will need different connectors depending on what you end up ordering. Mr Shades is selling many small items (piggyback, spade, thermal paste, power cable, rubber grommet etc.) It is a really tight fit to get the REX C-100 PID inside the machine. Thanks in advance!

Did you try with the SSR unit 40 DA or 40AA? The PID gives you consistency. It really pays off to assume nothing, and test everything. Not sure why that was the case. If the PID stays on when wired directly to mains power, you will need to figure out which power wire to tap into. I have not changed any of the P, I or D settings on my controller. One end of the wire should be a male disconnect connector, and the other end should be a spade connector. In the text it says M4, but on the picture, it highlights to use the M3. Steam will still be controlled by the steam thermostat. https://www.aliexpress.com/item/32975122837.html?spm=a2g0s.8937460.0.0.11b02e0edh0ELd.

Watching the steam temp with the PID is interesting (I know it has no effect on it, but it is cool to see how it reacts now) and it is definitely best practice to steam while its on its way up in temp, once it hits the set point it comes down for a while (mine settled around 130 before it started back up). My install went as smooth as I hoped all my wire colours and locations were identical to yours (Phewf). Perhaps you are refering to the video by Damian Witonski. If youre not comfortable installing this yourself, and taking on any followup maintenance, I think you would be much better off purchasing a machine that comes with a PID from the factory.

Hard to say how long it took because I was doing other things as well (dimmer switch, boiler pressure gauge, boiler rebuild, etc.) Hi Joe. 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. Perfect, came back here to ask this question! This kit has a pre-infusion timer. The silver box is coated with clear anodized aluminum with a brush-finished stainless steel front panel.

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. The label on REX-C100 says that it is produced by RKC, Japan but you never know for sure :-). I would not make it without you. 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. on orders over $49. 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. Thanks a lot for the answer. I installed an Auber PID on my Gaggia Classic earlier this year. Remove the cover assembly and filler funnel by unscrewing the two small screws at the rear of the top. 3.

QB-T7100 48*24mm Programmable Digital PID Temperature Controller AC/DC 85-250V This would also allow you to switch to PID-controlled brew mode simply by lowering the PID temperature. If not, can you think of any potential mistakes I made along the way? Hey. European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible.
