wrong temperatur

hi, I completely recreated my configuration.h file. (marlin 02000903) now a temperature of 75 degrees is displayed on both sensors. when I load the old firmware, it's 22 degrees again, which is normal. my other printer shows it too. I forgot something somewhere or set it wrong. I don't know where now.
I have already executed and saved the m149 c command. no change. where else can you influence the temperature?
I have set the same temp_sensor in both versions.
#define TEMP_SENSOR_0 1
#define TEMP_SENSOR_1 0
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_3 0
#define TEMP_SENSOR_4 0
#define TEMP_SENSOR_5 0
#define TEMP_SENSOR_6 0
#define TEMP_SENSOR_7 0
#define TEMP_SENSOR_BED 1
