<p>Actually there is a way - but it's kind of sneaky! Set the control cards you wish to change to STRINGS and give them equation names: STARTTIME, STOPTIME, TIMESTEP, ATOL, DTOL etc,</p>
<p>Then drag out one of the equation components and define these equation names / values for one of your cases. Make sure to change the name of the equation component to something descriptive: MAY_JUNE_0PT25HOURS for example When you are finished, test it to make sure it runs and then right click on the equation component in the assembly window and choose SAVE. Pick a location in the Studio/Proformas directory that you'll remember and save it there. Repeat this process for each of the simulation cards that you wish to create. Then choose the Direct Access --> Refresh Tree option to re-load the libraries. Now you've got a library of control cards that you can drag out and use each time you'd like a change.</p>

<p>Vincent,</p>
<p> There is not a way to save more than one set but it is an interesting idea! </p>

<div dir="ltr">Hi all,
<div> </div>
<div>I am relatively new to TRNSYS and maybe this is an obvious question, but I couldn't find the answer in the documentation.</div>
<div> </div>
<div>Is it possible to save different pre-sets of Control Cards? I will have to do a lot of simulations with different durations and time steps, but I wish not to manually change all the input of the control cards every time I do a simulation with, for example, a different .BUI file. </div>
<div> </div>
<div>For example; I would like to have simulations for four seasonal representative weeks of the year (21-st-28th of March, Jun, Sep, Dec) with a time step of 0,5 hour, and also half a year with a time step of one hour. I want to save the control cards, so I don't have to change the simulation start and step hours, the time step and the tolerances all the time.</div>
<div> </div>
<div>I hope my question is clear and that you can help me. Thanks in advance,</div>
<div> </div>
<div>Regards,</div>
