[TRNSYS-users] Weather time step

[freppelw at noirot.fr]

Thank you David for your reply.
I also realized that if I choose a time step less than 1 hour, the dew 
point temperature is approximated between entire hours. I cannot find 
the calculation rule in the documentation.
Do you have any idea where I can find it?

Best regards

Wirich
