[TRNSYS-users] Solar Thermal Collector outlet temperature

[Arnaud Candaele]

Hi,

Thank you for that answer !
Indeed I wasn't changing the area. But then, how is actually used the entry
"Number in series", if it's not used to automatically compute the total
area ? Is it just there as a reminder ?

Thanks a lot,
Arnaud.
