[TRNSYS-users] equation

[Isabelle BRUYERE]

Michaël,

Thanks already.

But when a constant is defined in the control card, can I use it in an 
equation which is defined in an equation bloc on the assembly panel? Or do 
I have to write that equation in the control card too ? (hope it is clear ...)

Best regards,

Isabelle
