> Dear TRNSYS users,
>
> is it possible to start a TRNSED application from a batch file without
> having to select a file and klicking something somewhere?
> So far, I succeeded in starting the exe with a batch file like this:
>
> @echo off
> start "" "MyTrnsedApp.exe"
> exit
>
> But I still have to klick ok in the popup window, choose the .trd file and
> then start the simulation manually.
>
> Any ideas? I am free to migrate to other ways than batch files...

>>
>> Variable=LT(T_Moving_Average,16)
>>
>> Then feed the result of the Variable equation (a one or a zero) to a
>> run-time calculator and the output from the run-time calculator to another
>> equation:
>>
>> OK_24=GT(Runtime,72)

>> Then use this equation as the control for your chilled ceiling.
