However its a 20K pot in series with a 270K resistor. So at best the pot can tweak but cannot change from 100vdc fsd to 250vdc fsd. I added a 470K resistor to do that. However the price is the multiplication factor of 2.7. I had thought of reprogramming the uncontroller which is an STM8. But on second thought the path is a potential can of worms which could brick it and distract me from the hot water project. So deffered for a future date. Azhaque Edited 2025-01-28 01:13 by azhaque
