You can do this but in a slightly more indirect way. Say that you
have a 3 node tank and that the temperature of the 3 nodes are given by
outputs 21, 22, and 23 of UNIT 35. You will need to write an equation such
as:<br>
<br>
EQUATIONS 1<br>
tempToWatch = isRun1*[35,21] + isRun2*[35,22] + isRun3*[35,23]<br>
<br>
isRun1, isRun2 and isRun3 are all new variables that will be defined both
in the input file and in the parametric table. You can write:<br>
<br>
CONSTANTS 3<br>
isRun1 = 1<br>
isRun2 = 0<br>
isRun3 = 0<br>
<br>
for each run that you make, all three of the constants must be set and
only one of them should be set to a value of 1; all others should be zero.<br>
<br>
Lastly, you will need to go through the deck and replace the text [35,21]
with the variable tempToWatch.<br>
Kind regards,<br>

I'm trying to simulate a DHW system, and I would like to make a parametric
run using TRNedit. <br>
In this parametric study, I would like to change the node of my storage
tank which is use to regulate my DHW system.</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
In TRNedit, the TRNSYS outputs are referenced like this: [Unit#, Output#]</font><font size=3>
</font><font size=2 face="sans-serif"><br>
Is it possible to replace the Unit# or the Output# by a constant or an
equation? </font><font size=3><br>
</font><font size=2 face="sans-serif"><br>
Example:</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
TANK: </font><font size=2 face="Courier New">UNIT 35 TYPE 534</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
[35,21] is the temperature of the 1st node of my tank</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
I want to replace [35,21] by [35,x], x will vary every new simulation following
my parametric table.</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
I do not undertand very well the properties of the object: [Unit#,
Output#]</font><font size=3> <br>
</font><font size=2 face="sans-serif"><br>
If it's not possible is there another solution to this problem?</font><font size=3>
<br>
