Open Studio 1.5 Radiant Panel Surface Group Error
I am getting the following error while trying to model a low temp radiant system:
Program Version,EnergyPlus-Windows-64 8.1.0.009, YMD=2014.11.14 10:36,IDD_Version 8.1.0.009
** Severe ** IP: IDF line~572 Object=ZONEHVAC:LOWTEMPERATURERADIANT:SURFACEGROUP, name=LOW TEMP RADIANT VAR FLOWCEILINGS, Required Field=[Surface 1 Name] was blank.
** Severe ** IP: IDF line~572 Object=ZONEHVAC:LOWTEMPERATURERADIANT:SURFACEGROUP, name=LOW TEMP RADIANT VAR FLOWCEILINGS, Required Field=[Flow Fraction for Surface 1] was blank.
** Warning ** IP: Note -- Some missing fields have been filled with defaults. See the audit output file for details.
The idf looks like this:
ZoneHVAC:LowTemperatureRadiant:SurfaceGroup,
Low Temp Radiant Var FlowCeilings; !- Name
and nothing else follows after this, so the surface names and flow fractions are missing (below is cut and pasted from EP input output ref):
ZoneHVAC:LowTemperatureRadiant:SurfaceGroup,
Zone 1 Radiant Surfaces, !- name of surface list
Zn001:Flr001, !- Surface name 1
0.75, !- Flow fraction for surface 1
Zn001:Roof001, !- Surface name 2
0.25; !- Flow fraction for surface 2
