RE: Type56, small timestep

[Michaël Kummert <kummert@xxxxxxxxxxxxx>]

Timo,

The TRNSYS time step can be less than or equal to the Type 56 wall time
base. In your case, you can for example use a 3-min (0.05h) time step for
the Trnsys simulation and a 1 hour time base for the wall transfer
functions.

Please note that the starting time of the simulation MUST be a multiple of
the Type 56 Time base. You cannot start the simulation at 0.05h, for
example.

If you use hourly weather data file, the right start time for a yearly
simulation is ALWAYS 1 for any time step (whether or not you use Type 56).

Regards,

Michaël Kummert
