[EnergyPlus_Support] Heatpump W-2-W Model & Node fatal Error!





Dear all,
 
I have the following problem when running the simulation. See below .err file!  I hope you can help me with this.
 
System information to model
 
1 X Air Loop
- Central AirHandlingUnit
 
2 X Plant Loops:
- Heating --> Heatpump:WaterToWater:EquationFit:Heating
- Cooling --> Heatpump:WaterToWater:EquationFit:Cooling
 
2 X Condenser Loops:
- GroundHeatExchanger:Pond connected to the SourceSide of heating plant loop
- GroundHeatExchanger:Pond connected to the SourceSide of cooling plant loop
 
Problem
I have checked the nodes, connectors, splitters en mixer arrangement and plant and condenser plant loop object. However, the simulation still ends up with node error comments!  
 
Question
Possibliy Í'm forgetting something.
Is there a limit on the length of the node names within EnergyPlus? Or, do the node names require to have sort of known structure? 
Or, you may think the problem is something else?
 
I hope you can help me further with this. Thanks in advance.
 
 
Best regards,
Ehsan
