ATTRIBUTES
	Pallete = true;
	Icon 	= "icon/heat_flow"; 
	Brief 	= "Model of a very simple valve for setting the energy flow with a controller.";
	Info 	=
"== ASSUMPTIONS ==
* nothing happens in this valve

== SET ==
* MinHeatFlow: the Minimum Heat Flow Allowable in the valve;
* MaxHeatFlow: the Maximum Heat Flow Allowable in the valve;

== SPECIFY ==
* the HeatFlowFraction (the model requires an inlet signal, also you can use a controller for setting the HeatFlowFraction)
";

PARAMETERS

	MinHeatFlow 	as power	(Brief="Minimum of Heat Flow",Default=-1000);
	MaxHeatFlow 	as power	(Brief="Maximum of Heat Flow",Default=1000);
	
VARIABLES

out HeatFlow 			as power	(Brief="Heat Flow", PosX=0, PosY=0.60,Protected=true);
in	HeatFlowFraction 	as fraction (Brief="Flow Signal", PosX=0.50, PosY=0,Protected=true);
	
EQUATIONS
"Heat Flow"
	HeatFlow = MinHeatFlow + HeatFlowFraction*(MaxHeatFlow-MinHeatFlow);
