hello, im trying to use a marzocco e.1.005 temp probe on a 2 boiler system. the display reads 32f and does not change with water temp. ive uploaded new versions to 1.1 to both master and slave boards. also verified change in resistance at the green connector temp2 rtd- rtd+ . Not sure where to trouble shoot further. what pins on the esp32 correspond with rtd+/- temp2, maybe there is a bad trace on the board

jumpers are placed correctly according to the document
