Hi Omar,
To my knowledge Hirsch & co have never properly explained these error
messages to this group. I regularly find the program won't accept the
design pump values.
Basically the program doesn't like your combination GPM, head, and kW
entries. Usually, if you let the software autosize the GPM or head (or
both), the error messages will disappear.

Dear All,
How significant are the following warnings and why are they caused? In our
baseline model we suddenly started having probably around 100-200 of these.
CURINV: Result out of limits for CURVE:
-0.035642 0.078769 1.353483 0.015932 -0.369414 0.000000 0.000000
0.000000
X, Y, and Z: 1.300000 0.000000 1.352446 MMDDHH: 8 26 9
CURINV: No real root for CURVE:
1 1.353483 0.015932 -0.369414 0.000000 0.000000 0.000000
These are related to our chilled water pumps.
Thanks for any help,
