Hi All,

I am modeling a building with water source heat pumps. I have a WLHP loop with a boiler and a fluid cooler attached to it. When I run the simulation, I get a message in the simulation file:

CURINV: No real root for CURVE:

1 0.449745 0.027043 -0.000444 -0.028325 0.000285 0.001570

This error seems to be referring to the fluid cooler curve: FluidCooler-FluidCap-fApp&WB . I am letting eQuest auto-size everything. Any ideas on how to solve this?

Thanks,
