There are four buttons on the front: SET, run-program, up-arrow, down-arrow. So far the temp range Ive seen when the heater cycles on/off (after ~30 mins of warming up) is ~90C to ~97C. Leave this cable longer than needed for now, it will be trimmed and terminated later. As for steam, the guide I wrote leaves the steam function completely untouched. Posted by 4 years ago. Pull the cover assembly off by pulling upwards, and disconnect the ground cables. You can use the sensor reading on the PID display to know when to start steaming. I have changed the default value of the SL parameter to work with the RTD sensor (K thermocouple was default). I started with 103, and bumped it up to 105. Two different colors of the controller box are offered, silver and black. Hi Miguel. Using pliers to pull the connectors can pinch them on even more tightly, making them extremely difficult to remove. I hesitate to identify wires by their color, as the wire colors in the Gaggia seem to vary from year to year and from region to region. Despite the K02 indicating K-type, it was advertised as supporting multiple types including PT100. I adjusted the calibration offset on the PID +5.5 degrees to read 212 degrees.Have you any suggestions of more accurately calibrating the PID and TC? Adding pre-infusion would require either a different and significantly more sophisticated PID, or integration with something like a microcontroller. great article !!!! 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. $149.99 . One bit of note and a request. robert kujawa 348 subscribers Subscribe 85K views 1 year ago In this video I'll install a PID unit on my Gaggia.

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. Have you noticed any problem using REX-C100FK02 and RTD PT100? Regarding the M4 screw/ thermocouple, is it possible to amend the picture? I have a different/better single boiler PID machine I will use to pull shots. hide. 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. This is really a DIY project. on orders over $49. Im sorry about that, Eric. You can get away with lighter gauge wire for the mains connection to the PID, as the PID draws very little current.

In the text it says M4, but on the picture, it highlights to use the M3. Each segmentcan be set by the user with 0.1 seconds resolution. I did that exercise before installing the PID, behavior should be identical as that time. The kit installation is fully reversible. Well I ordered the wrong thread. Is this typical? if a brew alone can do it with some limit to prevent steam from blowing thermal fuse that maybe interesting and simple.

It also means that you can only see the temperature and access the PID buttons from the top. Warning! Their kit is convenient, and is the way to go if someone doesnt feel ready to take on a 100% DIY project. I strongly suggest checking which switch terminal switches the mains. 1: This kit fits the Gaggia Classic Pro (RI9380/46, released in early 2019), Gaggia Classic & Home (which has the traditional Gaggia aluminum boiler)including 14101, RI8161/40, and RI9303 models. 2: The add-on item option "extra wire defeating auto-off timer" is for the Gaggia Classic Pro European model (RI9480, 240V), which has the auto-turn-off timer feature. I'd like to increase the brew temp a couple of degrees but have no idea how to do this. 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.
