[Bldg-sim] Hot Deck Schedule

[eric wang]

Hi eQuest Folks,
 
I model a PIU sysem with VAV box. I added a gas furnace for morning warm-up and tried to use hot deck schedule to control the temperature of heating supply air such as 80F. From 1-7 am, hot deck T is 80. For the rest of the day, it is zero because I want to turn off gas furnace.  In the INP file, the parameters are as follow. 
 
SET-DEFAULT FOR SYSTEM          
   TYPE = PIU
   HEAT-SET-SCH     = "Gas Furnace"
   HEAT-CONTROL     = SCHEDULED
 
However, after checking the hourly report, i found the heating coil (gas furnace) is always on even the hot deck temperature in the Gas Furnace schedule has been set to zero. Does anyone have any ideas about what the problem is? Your feedback and sugggestions are highly appreciated.
 
Thanks
 
Shaojie
