How protect analog input connected to thermistor through long wires
Do this on the inputs. The variable resistor is the remote thermistor.

How concerned are you, about voltage drop across the 10,000 ohm resistors?

Notice we use the 1uF to heavily filter the trash injected.

The assumption is that the injected electric-fields and magnetic-fields have ZERO average current, and thus heavy filtering ---- by a capacitor or in software ---- is all you need to do. 

Thus I'm having the 1uF capacitor (3 of them) replace the TVS.
