[EnergyPlus_Support] Bug/Problem report, ContFanCycComp will cause error.

["waspoorboy" <mingsbox@xxxxxxxxxxxxxx>]

I don't know if I should call it a bug.
Just want to share my discovery.
------------
Description: If FURNACE:BLOWTHRU:HEATCOOL use CycFanCycCoil,
but COIL:DX:CoolingBypassFactorEmpirical use ContFanCycComp,
there will be a lot of warnings like the below:
The reason I report this is because the error message didn't
tell me I should use CycFanCycComp.
I tried to correct the Air volume flow rate but doesn't help,
and before I went to check the weather file to see if
Temperature/Enthalpy wrong, I read Message#1228 and figure this out.
The error message looks also similar to Message#1376,1384,1385
which Linda and others suspect the problem might come from
weather file.
To reproduce this error, simply open FurnacewithDXSystem.idf
and change CycFanCycComp to ContFanCycComp in 
COIL:DX:CoolingBypassFactorEmpirical 
When corrected back, the whole bunch of warnings are gone.
Hope this discovery will help some users in the future.
