[Equest-users] capacity smaller than secondary demand

Hi, thanks,
This is what is confusing me. The PS-D Circulation Loop Loads report says the net loop load is 251 kBtu/h. The heat pump and boiler loads in the PS-C report agree with this. Nothing in the SIM file, except for this warning message, points to a problem.
For LEED, messages such as this have to be explained. It just raises the question of how many of the other warning messages are real.

The Secondary number comes from the Loop design Load。you can see the PS-C report.

Hi everyone,
I’m working on a loop-to-loop heat pump model. My hot water loop has a coil load of 231.8 kBtu/h, from the SS-D and PS-D reports. To this loop, I have 710 kBtu/h of heat pumps and an 846 kBtu/h boiler attached, which reasonably matches the primary number.
But, for some reason, the message below is telling me my secondary load is 10x the size that it actually is!
**WARNING**********************************************************************
Loop: Hot Water Loop heating capacity is smaller
than the secondary demand. Primary= -1537010.
Secondary= -2291187.
Does anyone happen to know where this secondary number actually comes from?
Thanks,
Shaun
