Program description

Instance	Type	Task
X1	FB_BACnetAVSetpoint	Input of the value for interpolation point X1
X2	FB_BACnetAVSetpoint	Input of the value for interpolation point X2
X3	FB_BACnetAVSetpoint	Input of the value for interpolation points X3
X4	FB_BACnetAVSetpoint	Input of the value for interpolation point X4
Y1	FB_BACnetAVSetpoint	Input of the value for interpolation point Y1
Y2_3	FB_BACnetAVSetpoint	Input of the value for interpolation points Y2/Y3
Y4	FB_BACnetAVSetpoint	Input of the value for interpolation point Y4
Scale	FB_BA_Chrct04	The function block calculates the set value characteristic curve for the current room temperature, depending on the outside temperature.
Sp	FB_BACnetAVDisplay	Output of the calculated, simple room temperature set value. It is output at the outputs rSpHtg, rSpCol and rSpErc.
