[TRNSYS-users] value of times steps

[David BRADLEY]

Prof Bina,

   Values of outputs at previous time steps can be obtained from Type150 
in the standard library or from Type661 in the TESS Controllers library. 
I am not aware of any components that read ahead in the weather data so 
obtaining Tsky (or anything else) at time t+1 would require writing a 
new component.

kind regards,

  David
