dear trnsys users,
I have to add the following algorithm into the equation:
if Ta < 15 ta= 15 and if Ta> 23 Ta=23
How can I do this?
Thanks
Roberto

Unfortunately, there is no if in the equation...

TRNSYS-users@cae.wisc.eduhttps://www-old.cae.wisc.edu/mailman/listinfo/trnsys-usersmaybe I'm wrong, but I don't think you can program that into an equation.
If I were you I'd program it in a type. It is really easy, you need onw input and one output, and you could even program the type with two parameters max and min and these numbers (15 and 23) would be parameters and you could easily change them anytime you want.
Regards.
Jaime

First you need to add an equation from assembly folder
Second, add input as tainput
Third, add output as taoutput
Forth, insert this _expression_ on the taoutput " lt(tainput,15)*15+gt(tainput,23)*23 " for sure without " "
Just this

TRNSYS-users@cae.wisc.eduhttps://www-old.cae.wisc.edu/mailman/listinfo/trnsys-usersHello, Roberto.
You can define an output (say Ta1) in the equation proforma where
Ta1=Max(Min(Ta,23),15)

You can also use 'min' and 'max', for your example:
max(min(Ta, 15),23)

max(min(Ta, 15),23)

---------------------------------------------------------------
That's a good one, but it would be the opposite
min(max(Ta, 15),23)
anyway, this is definitely the best solution, you don't have to program anything.
