Nodes of different colours represent the following:
Solid arrows point from a parent (sub)module to the submodule which is descended from it. Dashed arrows point from a module being used to the module or program unit using it. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

| integer, | intent(out) | :: | AvailStatus |
Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed arrows point from an interface to procedures which implement that interface. This could include the module procedures in a generic interface or the implementation in a submodule of an interface in a parent module. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

! SUBROUTINE INFORMATION:
! AUTHOR Peter Graham Ellis
! DATE WRITTEN February 2004

! PURPOSE OF THIS SUBROUTINE:
! Set AvailStatus indicator for a plant loop, primary air loop or ZoneHVAC component.
! METHODOLOGY EMPLOYED:
!
! USE STATEMENTS:
USE DataLoopNode, ONLY: Node
USE DataPlant, ONLY: PlantAvailMgr
IMPLICIT NONE ! Enforce explicit typing of all variables in this routine
! SUBROUTINE ARGUMENT DEFINITIONS:
INTEGER, INTENT (IN) :: SysAvailNum ! Number of the current scheduled system availability manager
INTEGER, INTENT (IN) :: PreviousStatus ! System status for the previous timestep
INTEGER, INTENT (OUT) :: AvailStatus ! System status indicator
! SUBROUTINE LOCAL VARIABLE DECLARATIONS:
REAL(r64) :: DeltaTemp
! FLOW:
DeltaTemp = Node(DiffTSysAvailMgrData(SysAvailNum)%HotNode)%Temp - Node(DiffTSysAvailMgrData(SysAvailNum)%ColdNode)%Temp

ELSE IF (DeltaTemp <= DiffTSysAvailMgrData(SysAvailNum)%TempDiffOff) THEN
AvailStatus = ForceOff
ELSE
IF (PreviousStatus == NoAction) THEN
AvailStatus = ForceOff
ELSE
AvailStatus = PreviousStatus ! No change, but not "NoAction"; it should always be on or off.
