ITC100 Thermistor

I am trying to use the ITC-100 with a Semitec 104NT thermistor. I can’t get the system out of “orAL” alarm mode. I’ve connected the sensor between pins 3 and 4.
I’ve tried changing the Sn parameter to 20 or 21. The display shows a PV value that is either 154 or 635 respectively.
I’ve also tried connecting or disconnecting pins 4 and 5. It changes the PV values but the unit is still in “orAL”.
Please advise.
Thank you,

Please note the sensor types supported by the ITC-100 are: K, S, Wre, T, E, J, B, N, CU50, PT100
Otherwise, it will display “orAL”.
