Hi Shaun,
Thanks for the reply. I know that by autosizing these will go away, but
this is regarding the baseline model and I have to enter specified
kW/GPM values. Actually these warnings started appearing after I entered
these manually.
We have lots of pumps in our model, so we now have a lot of warnings. I
guess that would be a problem for the LEED review.
Omer.
