PID controller install took 4 nights, mostly my own fault
Finally got my Rancilio Silvia stable at 200F after fighting the wiring for what felt like forever. Turned out I had the thermocouple reads reversed on the XMT7100, so it was heating full blast thinking it was cold. Took me 3 evenings just to notice the display numbers going down as the boiler got hotter. Anyone else struggled with the probe placement on these cheap controllers?
