K8203 extruder thermistor

Have upgraded to K8203 direct drive, assembled the extruder and installed the thermistor supplied.

Marlin v2.2 firmware has been uploaded to the printer but the temperature reading shows 200 deg C on my Repetier trace at start up.

Could Vellman confirm the specification of the thermistor supplied with the kit so that I can be sure the definition in Marlin Configuration.h file matches appropriately?

The current definition is:-
#define TEMP_SENSOR_0 5

(5 is 100K thermistor - ATC Semitec 104GT-2 (Used in ParCan) (4.7k pullup))

Now as this gives 200 deg C reading at start up surely it cannot be the one supplied!

Or is there some other problem?

Please help.
