What is the difference between a SC41 and a SC42 sensor?

The difference is the temperature sensor. The SC41 has a Ni100 temperature element and the SC42 has a PT1000 temperature element. PT1000 is a better temperature element, but some old electronics will not accept a PT1000 temperature element, so the SC41 is still available.
