Re: [EnergyPlus_Support] About temperature setting

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

Many of the examples use the DUAL SETPOINT WITH DEADBAND control type with 
setback/setup during unoccupied hours.  With this type of control, the space 
temperature is allowed to float until conditions reach the setback/setup 
temperature, then there will be loads to maintain that tempeature.  If you want 
to completely shut off the HVAC system during unoccupied hours, then use the 
system availability manager to do so.  If you want to run the fans, but not 
actively control the space temperature, then you can schedule off individual 
components (such as the cooling or heating coils) or you can set the thermostat 
control type to zero during those hours.
