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.

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.
REAL(r64) FUNCTION SupSATResidual(TempSupHeater,Par)
! FUNCTION INFORMATION:
! AUTHOR Richard Raustad
! DATE WRITTEN July 2005
! MODIFIED
! RE-ENGINEERED
! PURPOSE OF THIS FUNCTION:
! Calculates residual function (outlet temp - maximum supplemental heater SAT)
! Outlet temperature depends on the supplemental heater load which is being varied to zero the residual.
! METHODOLOGY EMPLOYED:
! Calls SimulateHeatingCoilComponents to get outlet temperature minus the maximum supplemental heater SAT
! at the given supplemental heater load and calculates the residual as defined above
! REFERENCES:
! USE STATEMENTS:
USE HeatingCoils, ONLY: SimulateHeatingCoilComponents
IMPLICIT NONE ! Enforce explicit typing of all variables in this routine
! SUBROUTINE ARGUMENT DEFINITIONS:
REAL(r64), INTENT(INOUT) :: TempSupHeater ! supplemental heater load at maximum SAT
REAL(r64), INTENT(IN), DIMENSION(:), OPTIONAL :: Par ! par(1) = PTUnitNum
! par(2) = FirstHVACIteration

! FUNCTION LOCAL VARIABLE DECLARATIONS:
INTEGER :: PTUnitNum ! PTHP index
LOGICAL :: FirstHVACIteration ! FirstHVACIteration flag
PTUnitNum = INT(Par(1))
! FirstHVACIteration is a logical, Par is real, so make 1.0=TRUE and 0.0=FALSE
IF(Par(2) .EQ. 1.0d0)THEN
FirstHVACIteration = .TRUE.
ELSE
FirstHVACIteration = .FALSE.
