[EnergyPlus_Support] Controlled temperature

["aboyemeplus" <Merid.Aboye@xxxxxxxxxxxxxx>]

Linda,

I do realize that "Zone Mean Radiant temperature" is not the 
heating/cooling setpoint temperature. I was trying to confirm 
whether or not the program compares the User Input setpoint 
temperature to the Zone Average Air temperature. The output 
spreadsheet files do not report "Zone/Sys Air Temperature" despite 
the fact that this variable is selected in the "Report Variables" 
table. Your answer below does confirm that "Zone/Sys Air 
Temperature" is the contrlloded variable, but I still would like to 
be able to report it. The Error file indicates that this 
variable "is requested but not generated", without further input as 
to why it is not being generated. Any hints on how I can generate 
zone average Air temperature data is greatly appreciated.

Zone Mean Radiant Temperature is not the heating/cooling setpoint
temperature.  The controlling temperature is for air temperatures at 
this time.

Report "Zone Mean Air Temperature" or "Zone/Sys Air
Temperature"  (they are equivalent and usually the same) to get 
those.
