Dear Knut,

Thank you again for the answer. I will investigate this. I will try to average it in 15 min to see what happens. 

Best Regards

Eleni

Eleni,

I am not sure, but I think it is possible that your problems are caused by
having 5 min intervals in your data. Since 5 min = 0.083333 ... hours has
an infinite number of decimals, after a while there might be a small time
shift between simulation time and time in your weather data file. This
could also be the reason for the warning from the printer. If it is
possible for you, I would suggest that you change your weather data
interval and also your simulation time step length to a number with a
finite number of decimals, for example 15 min = 0.25 hours. If you choose
to have a simulation time step length smaller than the intervall in your
weather data, TRNSYS will interpolate linearly between data lines (except
for radiation, which is treated in a different manner, see manual).

Best regards,
Knut Erik
