[TRNSYS-users] Python

Dear Tim



The connection with python works now, thanks!

But another question came up:



I am testing an algorithm which takes the weather forecast of the following
48 hours in to account. What do you think is the best way to give the
controller the required forecast?



I thought of a time delay using type 150 to shift the whole simulation 48h
backwards and then the undelayed weather output of type 15 would represent
the forecast.



But type 150 allows only a shift of 25 time steps and maybe there is a more
elegant solution than adding type 150 in series or to change the default
range of the type’s time steps (which I am not familiar with).



Thanks for your help.



Best regards,



Frederick
