It always used to be the case that you got a reading of -273C if the thermistors are not connected; but maybe that has changed in RRP's 0.78 firmware. I'm fairly sure my 0.78a-dc42 still shows -273, however my fork does the temperature readings differently.

Interesting, my second hot nozzle thermistor reading with the second nozzle disconnected is reading -273.1C, as I expected. Perhaps your SAM3X has a small ADC offset.
