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. When the pump runs, it vibrates the chassis and it will be a matter of time before it cuts through the wiring insulation. Once you are able use the PID temperature readout to determine exactly what the steam cycle is, you know when to start steaming for more or less endless steam. Which Auber PID for Gaggia Classic? It shows that neutral cables coming from thermostats are connecting each other under the steam switch but mine are connected under the main switch. In mine, correct terminal was crosswise of yours. Hi Chris, thanks for the reply. One question, Ever thought about adding a pre infusion feature? I am not surprised, Mr Shades runs an honest business, and those parts are being offered at low prices. What you describe looks very much like the steam thermostat cycle. It doesnt matter which mains terminal is connected to hot and which one is connected to neutral. The best way to find is: 1-Connect one cable to the mains connector at the back where it is showing N sign meaning Neutral. Final note: before going down the PID route, the easiest modification to make, and the best starting point for Gaggia Classic modifications, is lowering the brew pressure. Might be easier for most folks to buy an M4 screw, type K, thermocouple direct vs trying to get the probe version then another adapter. If you want to defeat that auto-power-off feature, please add this piece of wire to your order. Hi, I just completed the DIY kit last night using your guide and it all went perfectly! Submit a Request Call Us at (888)-389-4123. This kit doesn't control the steam temperature nor has the pre-infusion function. Inside the GC, all bets are off as to wire colors, aside from green for ground, and even then, I wouldnt assume anything. 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. $285.00. Do not undertake this procedure if you are not comfortable or uncertain. You can use the sensor reading on the PID display to know when to start steaming. As for your PID always remaining on, it looks like you wired it to the unswitched mains, instead of the switched power. It will depend on the beans you use, and your palate. however the one SSR is nice and the modification gives upgraded steam with the solder mod. We ship every business day from our two warehouses located in Milton, Ontario and Calgary, Alberta. The best part is I am only in about $40 on my kit compared to around $150 for the pre made kits. Its stimulated a lot of interesting discussion! European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Hi Peter. Hi Chris, Please be sensible and install a grommet anyway! If you want to defeat this feature, please add this optionto your order. Shop for it now! I guess I could revert the machine and see what I get. Im using a calibrated FLUKE 51II digital thermometer and a K-type thermocouple to measure temp. Mains is house current. 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. Auto-tuning PID cooling/heating control (Markings can be found on front side of the plug) 2-Check the color of the cable which shows L sign on the plug- meaning Live. Home; Search; Log in; Sign up; Updates: Click here to visit our store! However I now need to connect steaming and brewing circuits in parallel rather than serial because steaming circuit will not be closed unless I turn on steaming switch and supply power to steaming SSR. Check for wire that might have been too aggressively stripped, where some of the conductor might have also been cut away. For the Gaggia Classic, taking into account the temperature drop between the boiler and the group head (5-8 degrees C), the PID target temperature should be set to about 103 degrees C or 220 degrees F at sea level. My only concern is that Mr Shades has two types of SSR units 40AA and 40DA. 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. Fortunately, no damage done, and you can easily revert your changes. Sure enough, it powered up. if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple. The cup warmer does seem a bit hotter than before (but have only used twice since installing, so Ill have to pay attention). My plan is to install the Rex C100 first using your instructions. Does the wiring youve supplied automatically shut the PID unit off when you engage the steam switch? save. I have installed the supply cable for PID unit using piggyback spade connectors.

If its closed it takes longer for temperatures to drop, but still goes to 102 before the it power cycles. This would explain the constant switching on and off. 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). I start to run the steam at about 130 in the heating cycle on my setup. I agree, the PID is a gamechanger. I installed the PID so that there are no permanent modifications to the machine, and the Gaggia can be returned to factory condition at any time. Monitor and display the boiler temperature precisely. Thank you Chris for the awesome write up. Thermocouple: J,S,K,E,Wre3 ~ Wre25 3-Connect the other cable to the terminal on the on off switch, which is on top of or below the Live cable. Thread the thermocouple wire through to the back of the machine, and out the same slot as was used for the other wires. Nikola. it is basically removing the main pump wire and re routing back to the PWM out. Please check KIT-GGX-EUinstead. 3. Attach the solid state relay to the inside back wall of the Classic, using a small bolt and nut.
