dear diego; i am javier mota from 3i-ingenieria, madrid. I am sorry, first iteration looks ok.but i show you something that take my attention. maybe because i don´t know the way type 109 works, so first sorry by my ignorance.
I show you the results.first, tmy2: 8280 Albacete/Los Llanos 1 N 38 57 W 1 51 704 At local stanadr time =1 T=4.6 in tmy2at tme =1 in output trnsys T=4.6 with time step=1 and trnsys T=4.6 with time step=0.25.
so time output TRNSYS=1 match meteonorm at hour 1. at time =2, for example: T=4.7 in tmy2 local stan. time=2 T=4.65 with time step=1 in output trnsys; time output=2 T=4.70 with time step=0.25 in output trnsys;time output=2 so at time=2, for example, numbers doesn´t match excatlybut i suppose and that must be ok this last 3 numbers 4.7,4.65,4.7 may be the same.
so, sorry, and thanks.

I had tried to reproduce this problem but Type109 gives me the right results for this initial value; I check the values of temperature. Could you please send me the project file and weather data that you are using? I may be able to help you.Best regards, Diego javier mota wrote:Hallo. I am javier mota from 3i-ingenieria,madrid.I make a program that reads tmy2. data file is TMY2, 8760 lines, one line one hour.I run simulation with time step 0.25i have seen that first iteration does not refer to file that reads type 109 in tmy2 format, all outputs are zero. But line 4th in the output file,(1 hour passed time) should match 1st line in weather data file, and so sholud be refered to the hour in local standar time? Due to interpolation in this element i am not sure that I could check results looking tmy2 and outputs; outputs does not match exactly tmy2 data expexted.May anybody confirm me this point?
