Question-and-Answer Resource for the Building Energy Modeling Community
 | 1 | initial version |
I downloaded the Chicago version of this file and ran in V8.0. The only change being the first calling point:
EnergyManagementSystem:ProgramCallingManager,
DataCenter_Main_Manager, !- Name
BeginTimestepBeforePredictor, !- EnergyPlus Model Calling Point
DataCenter_Main; !- Program Name 1
Same result as you describe. Then transitioned that file to V8.1 and the file with a different fatal error, assumingly because I changed the calling point.
** Fatal ** CheckForRunawayPlantTemps: Simulation terminated because of run away plant temperatures, too hot
So something along the way possibly got fixed. Checking Addressed_Issues-V8-1-0.html shows this:
Folder: EnergyPlus
CR Number: 9,367
Type: Defect
Addressed In: 13.11.20 V8.1.0.009 - rerelease
Synopsis for Users: EMS actuator Zone Temperature Control not found when using V8.1. This actuator was broken when moving initializations to correct other issues.
Further Details for Users: The user could use a program calling point other than BeginTimestepBeforePredictor, however, if this calling point is required, no workaround is available.
Although a different symptom that you decribe I suggest transitioning the file to the latest version of E+ to avoid bugs corrected along the way. Provide an update if you run into the same problem with the latest version of E+.
