Controller that takes as an input the room air temperature TRoo
and
the supply water temperature TSup
,
and outputs the commanded mixing valve position yVal
.
Based on the room air temperature TRoo
, and the user adjustable parameters
for the minimum supply water temperature TSupMin
,
the maximum supply water temperature TSupMax
and the room air temperature TRooMin
at which the supply water temperature is at TSupMax
,
the controller computes a set point for the supply water temperature.
This set point is then used with the measured supply water temperature TSup
as an input to a PI-controller that computes the commanded valve position yVal
.
