[TRNSYS-users] Adiabatic boundary wall in TYPE56

[David Bradley]

Dear Xavier,
   With a BOUNDARY wall, you have the option of defining the temperature on 
the other side of the wall as "userdefined" (either an input, a constant 
value, or a schedule) or as "identical." To define an adiabatic wall, 
simply set the boundary temperature to "identical"
Kind regards,
   David
