I'm working on a simulation with FCU and some SZRH units. In the output I'm getting a warning that I've not encountered before:

**CAUTION**********************************************************************

System: EL3 Sys8 (PSZ) (G.N1) could not successfully

allocate all energy to the 5-minute bins during

heating because of an equipment overload. The peak

load used in ECONOMICS will not include the fraction

due to the overload, but the PLANT reports will.

Mon/Day/Hour: 1 3 7 Energy: 1.4 Unallocated: 0.082

Could someone explain what this means? SYS8 is a chilled water SZRH.
