EnergyPlus-PythonPlugin: zone surface temperature out of bounds
I am using Python plugin to overwrite some variables from EnergyPlus (v9.4), such as: zoneSAT, zoneSAF, AHU-SAT, AHU-SAF, OAT. I tried to send back the original values, instead of modified variable values. I also tried to give back the modified variable values.
But both simulations crashed with errors: zone surface temperature out of bounds.
The eplusout.err file also shows warnings related with: PsyWFnTdpPb, PsyPsatFnTemp.
What are the possible solutions?
The errors:
** Severe ** Temperature (high) out of bounds [500.38] for zone="ROOM B2", for surface="WS_1F_WALL"
** ~~~ ** Environment=RUN PERIOD 2, at Simulation time=04/24 16:37 - 16:38
** Fatal ** Program terminates due to preceding condition.
...Summary of Errors that led to program termination:
..... Reference severe error count=68353084
..... Last severe error=Temperature (high) out of bounds [500.38] for zone="ROOM B2", for surface="WS_1F_WALL"
