blockAutomaticThermalControl
Extends from BuildingControlLib.BuildingControl.VDI3813.Interfaces.Partial.PartialFunction (Superclass for all function blocks to provide graphics and enforce implementation of functionality).
Information
Overview
Block that implements function of "Automatic thermal control" from VDI 3813 [1, section 6.5.17, p. 59 - 61].
Functional Description
"By means of Automatic thermal control (RA-FL section 6, column 16; informative function block Figure 38), the sunshade is used in unoccupied rooms to support heating or cooling by deliberately admitting or preventing solar heat inputs. This helps avoiding overheating in summer and reducing the heating load in winter. To this end, the application function processes the input information about the occupancy state of the room (Occupancy evaluation), the outdoor brightness (Brightness measurement), the room temperature (Temperature measurement) and the setpoints (Setpoint calculation) and, on this basis, generates positioning commands for the sunshade."[1, section 6.5.17, p. 59 - 61]
