[TRNSYS-users] Heat extarcted from a borhole

[David BRADLEY]

Ahlem,

  If you find the SCHEDULES in TRNBuild to be restrictive you can 
designate those values to be INPUTS (instead of SCHEDULES) and then pass 
them in from other components in your simulation. You can then define 
your schedules however you want (with Type14, with the components in the 
TESS Applications library, reading from an external file (using Type9), 
using an equation, etc.).

kind regards,

  David
