Enthalpy calculator

The function block calculates the following based on inputs temperature and
relative humidity:
Function range A (inputs Temp A and RelHu A):
 Enthalpy A
 Absolute humidity A
 Dew point temperature
 Wet bulb temperature
Function range B (inputs Temp B and Rel Hu B):
 Enthalpy B
 Absolute humidity B
 Enthalpy difference (Enthalpy A Minus Enthalpy B)
The results of the calculations are provided as DC 0...10 V signals or as internal,
analog signal.
