Re: [EnergyPlus_Support] COMIS venting modulation

["Michael J. Witte" <mjwitte@xxxxxxxx>]

This is a bug in version 1.2.0.029.  There are three COMIS report variables 
that are incorrectly summing instead of averaging.  In the rdd file, these are 
listed as:  

Zone,Sum,Opening Factor Multiplier for COMIS Venting Modulation[]
Zone,Sum,Inside Temp Setpoint for COMIS Venting[C]
Zone,Sum,Venting Availability[]

To see the expected values for these variables, you must report them at the 
"timestep" reporting frequency.  

This has been fixed for the next release (CR#6362).
