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 the 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.

/**
* --NORMAL IS 4.7kΩ PULLUP!-- 1kΩ pullup can be used on hotend sensor, using correct resistor and table
*
* Temperature sensors available:
*
* SPI RTD/Thermocouple Boards - IMPORTANT: Read the NOTE below!
* -------
* -5 : MAX31865 with Pt100/Pt1000, 2, 3, or 4-wire (only for sensors 0-1)
* NOTE: You must uncomment/set the MAX31865_*_OHMS_n defines below.
* -3 : MAX31855 with Thermocouple, -200°C to +700°C (only for sensors 0-1)
* -2 : MAX6675 with Thermocouple, 0°C to +700°C (only for sensors 0-1)
*
* NOTE: Ensure TEMP_n_CS_PIN is set in your pins file for each TEMP_SENSOR_n using an SPI Thermocouple. By default,
* Hardware SPI on the default serial bus is used. If you have also set TEMP_n_SCK_PIN and TEMP_n_MISO_PIN,
* Software SPI will be used on those ports instead. You can force Hardware SPI on the default bus in the
* Configuration_adv.h file. At this time, separate Hardware SPI buses for sensors are not supported.

*
* Analog Thermistors - 1kΩ pullup - Atypical, and requires changing out the 4.7kΩ pullup for 1kΩ.
* ------- (but gives greater accuracy and more stable PID)

* NOTE: (1) Must use an ADC input with no pullup. (2) Some INA826 amplifiers are unreliable at 3.3V so consider using sensor 147, 110, or 21.
* 21 : Pt100 with circuit in the Ultimainboard V2.x with 3.3v ADC reference voltage (STM32, LPC176x....) and 5V INA826 amplifier board supply.
* NOTE: ADC pins are not 5V tolerant. Not recommended because it's possible to damage the CPU by going over 500°C.
* 201 : Pt100 with circuit in Overlord, similar to Ultimainboard V2.x
*
* Custom/Dummy/Other Thermal Sensors
