Re: [EnergyPlus_Support] Re: Compact PTHP expanding issues
We are trying to track down your problem. If you add CycFanCycComp to
both the DX cooling coil and DX heating coil in the expanded file, the
file will run but has many other errors. You should be able to fix these
yourself.
Add the CycFanCycComp input (in the expanded file) just before each line
shown for each DX coil object.
Coil:DX:CoolingBypassFactorEmpirical:
CycFanCycComp,
0, !- Nominal Time for Condensate Removal to Begin
Coil:DX:HeatingEmpirical
CycFanCycComp,
-8, !- Minimum Outdoor Dry-bulb Temperature for Compressor
Operation {C}
