.BuildingSystems.Controls.SetPoints.Table

Information

This block can be used to schedule a set-point by using piecewise linear functions. For example, the instances

BuildingSystems.Controls.SetPoints.Table tabLinExt(constantExtrapolation=false,
                                             table=[20, 0.0;
                                                    22, 0.5;
                                                    25, 0.5;
                                                    26, 1.0]);
BuildingSystems.Controls.SetPoints.Table tabConExt(constantExtrapolation=true,
                                             table=[20, 0.0;
                                                    22, 0.5;
                                                    25, 0.5;
                                                    26, 1.0]);

will cause the following output:

For the default setting constantExtrapolation=true, the block outputs y=y1+offset for u ≤ u1, and y=yMax+offset for u ≥ uMax. Otherwise, the table is linearly extrapolated with a constant derivative.

Note that the first column must be strictly increasing.
