C14: Type of refrigerant
C14 defines the type of refrigerant. If your system includes pressure probes, the knowledge of the type of refrigerant allows you to convert
pressure into temperature.

Note: if the type of refrigerant is not specified, all the parameters concerning the measured variable will appear in bar. If the type of
refrigerant is specified, the pressure reading will be automatically converted into temperature and displayed on the basis of the unit of
measure as defined by C18.
C15: Minimum value of current or voltage inputs
C15 is the value measured when the input is given the min. possible signal, that is 0 V when using 0
