[TRNSYS-users] Partial (one month) weather data, 10min interval

[David BRADLEY]

Michal,
   This sounds like a bug that we have found and fixed in Trnsys17. We 
are in the final testing stages of the fix; could you please send me the 
project and the data file so that I can have a look?

   A couple of hints (although I do not think that these will solve the 
problem...):
- make sure that you set the "start day" parameter of Type16 correctly 
(it should be 152 for June 1).
- make sure that you set the simulation start time to 3624.
- your first method of specifying the timestep is the correct one. Set 
the simulation time step to a STRING variable called TIMESTEP and define 
the equation that you wrote below:

EQUATIONS 1
TIMESTEP = 1/6

Best,
  David
