Code:
#ifdef UseOutsideTemperatureSensor
#define OutsideTemperaturePin 15 // Inside temperature sensor, on analog 1
#endif
#ifdef UseInsideTemperatureSensor
#define InsideTemperaturePin 16 // Inside temperature sensor, on analog 2
#endif
On board it is analog pins 1 & 2, but in Arduino software it is 15 & 16, same pins, but different numbers. I do not know why.
