ThermistorType (07.046) defines the operation of the temperature feedback interface for DI/O 05 when Digitalinput5mode (08.035) is 1, 2 or 3.
If ThermistorType (07.046) = 0, the thermistor DIN44081 is designed to react like a temperature switch and therefore ThermistorTemperature (07.050) always reads 0.0°C.
If ThermistorType (07.046) = 1 to 3 is selected, the digital input operation of the terminal is disabled.
If ThermistorType (07.046) = 4, any thermistor can be used but ThermistorTemperature (07.050) always reads 0.0°C.
Parameter 07.047 Thermistor Feedback

ThermistorFeedback (07.047) shows the measured resistance. If Digitalinput5mode (08.035) is 2 then {Th} trip is initiated if the feedback value is higher than ThermistorTripThreshold
(07.048). The trip cannot be reset unless the feedback is below ThermistorResetThreshold (07.049). The default values for ThermistorTripThreshold (07.048) and ThermistorResetThreshold
(07.049) are the levels specified in the DIN 44082 standard.
