Below is a listing from the Marlin base that we are using for the Unified 2 Firmware. Any of the thermistor numbers below can be  entered into the "KNOWN_XXXXXXX_THERMISTOR_VALUE" in our firmware if you are using one that is not standard to your machine. You will also need to uncomment the "KNOWN_XXXXXXX_THERMISTOR" option to enable use of the specified thermistor number.

Special wiring and/or pin changes may be required for some thermistors depending on what board and/or thermistor you are using. Refer to the thermistor seller/manufacturer documentation on what value to use and how to connect it to your 3D printer.
