If the simulation stops after you see Warmup {1} on the DOS screen, then you can tell the program to report during warmup so you can see what's happening.

I have already tried to change the CHW Loop Setpoint Manager but the severe error is always the same, i mean the outlet temperature is every time different but is always too low.

It seems like your set point temperature for the plant loop is very low, check the temperature schedule in the SetpointManager:Scheduled
