I believe that when the simulation starts, and created the IDF expanded, there is a conflict between these branchs. I do not know how to solve this. Only used the HVAC templates. Maybe you can not use this due to the conflict. Has anyone seen this problem? Thank you Jim. Téc.

Sorry, i forget this.
The fatal error is:
** Severe ** GetFirstBranchInletNodeName: BranchList="BOILER_PUMP HW DEMAND SIDE BRANCHES", Branch="BOILER_PUMP HW DEMAND INLET BRANCH" not a valid Branch Name ** Severe ** GetPlant/CondenserLoopData: PlantLoop="BOILER_PUMP HOT WATER LOOP", Invalid condition. ** ~~~ ** The inlet node of the first branch in the Demand Side Branch List Name=BOILER_PUMP HW DEMAND SIDE BRANCHES ** ~~~ ** is not the same as the Demand Side Inlet Node Name=BOILER_PUMP HW DEMAND INLET ** Severe ** GetFirstBranchInletNodeName: BranchList="BOILER_PUMP HW DEMAND SIDE BRANCHES", Branch="BOILER_PUMP HW DEMAND INLET BRANCH" not a valid Branch Name ** ~~~ ** Branch List Inlet Node Name=Invalid Node Name ** ~~~ ** Branches in a BRANCH LIST must be listed in flow order: inlet branch, then parallel branches, then outlet branch. ** Fatal ** GetPlant/CondenserLoopData: Errors found in processing input.

I don't know why. Thanks for your helpness.
