How to simulate with warm storage tank or start on another day then January 1st? Thema ist als GELÖST markiert

[cj0]

Using a modified (heater removed) System Diagram XL solar house passive, SFD (single family dwelling) simulation always start at January 1st with a storage tank temperature of 9.1ºC at the bottom and 11.2ºC at the top layer.

I'd wish to start the simulation at a different date, or to set the January 1st tank temperatures to December 31st values (28.6ºC and 41.0ºC).

How to achieve this?

See menu "System Diagram", item "Preliminary simulation".
Over there the number of days can be set.
