The configuration diagram shows all function blocks active in the plant type. In this
example, these are the following types of function blocks:
• Boiler control including maintained boiler return temperature controlled via mixing valve
• Miscellaneous
• DHW heating
• Heating circuit 1
• Heating circuit 2
For additional examples, refer to subsection
16.1.4 “Examples”.
The configuration diagram shows the inputs and outputs preconfigured in the basic
module.
This means that for an input variable (e.g. the boiler temperature), an input terminal
(e.g. X1) has already been preconfigured per default.
For plant type H4-5, the following inputs and outputs are preconfigured in the boiler
temperature controller, that is, in function block “Boiler“:
Input variable Terminal Designation in diagram
Boiler temperature X1 N.X1
Boiler return temperature X3 N.X3
Output variable Terminals Designation in diagram
