blockAdjustTemperatureSetpoint

Enables the user to adjust the setpoint for room temperature

Extends from Interfaces.Partial.PartialFunction (Superclass for all function blocks to provide graphics and enforce implementation of functionality).

Information

Overview

Block that implements function "Adjust temperature setpoint" from VDI 3813 [1, section 6.4.5, p. 28 - 29].

Functional Description

"The operator function Adjust temperature setpoint (RA-FL section 5, column 4; informative function block Figure 19) converts a manual actuation to output information which is then available as input information to the application functions. The adjustment range is to be limited by means of parameters. The setpoint can be given in terms of either absolute temperatures or a relative offset from the default setpoint of the control system." [1, section 6.4.5, p. 28 - 29]

In the textual and informative description of the function the input is named T_SYNC.[1, section 6.4.5, p. 28 - 29] This value is never generated as an output by any other function. Furthermore the other operator and display functions have status inputs that have the ending _STA. Following this convention the input acronym has been changed from T_SYNC to T_STA.
