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.

! AUTHOR Chandan Sharma, FSEC
! DATE WRITTEN May 2010

! RE-ENGINEERED na
! PURPOSE OF THIS SUBROUTINE:
! To calculate the basin heater power for multi mode DX cooling coil
! METHODOLOGY EMPLOYED:
! The methodology employed is as follows:
! 1) If the number of capacity stages is equal to 1 and the CondenserType for stage 1
! is EvapCooled, then the basin heater power is calculated for (1-runtimefractionstage1) of DX coil
! 2) If the number of capacity stages is greater than 1, then
! a) If the CondenserType for stage 1 is EvapCooled, then the basin heater power is calculated for
! (1-runtimefractionofstage1) of DX coil
! b) Elseif the CondenserType for stage 2 is EvapCooled, then the basin heater power is calculated for
! (1-runtimefractionofstage2) of DX coil
