Material property Heat transfer

I hv ques regarding Material properties for heat transfer in CFX. It ask for Reference pressure and Temperature to calculate Enthalpy. But there is also option of Reference Specific Enthalpy and Reference Entropy. By default it is checked with value zero. Cant really find abt their use in help content. Does anybody know when and what values to set for Reference specific enthalpy.

These are used to reduce round off errors. Round off error is not often a problem in heat modelling so it is not used by default, but it can be so the option is there if you want to use it.
