Manuel, <br>
The only way is to change the source code and move the parameter to
an input, then recompiling the Type. The TRNSYS engine reads parameters
from the input file at the beginning of the simulation and stores them
internally. They are never reread so while you can make a parameter
value that is the result of a time dependent equation, only the initial
result of that equation at the very start of the simulation will be
used for the parameter value.<br>

<p class="MsoNormal"><span lang="EN-US">I see in the TRNSys docs that
variables
used in place of numerical values for parameter can’t be time-dependent

add an equation that chooses the right output depending on the time but
it’s
not possible because it will make too lots of trnsys modules.<o:p></o:p></span></p>
