The applications are presented in the form of basic diagrams, heat source versions and
extra functions. Heat source versions can be selected by setting the respective
parameters. If extra functions are required, the multifunctional inputs and outputs must

Basic diagrams

The plant diagrams presented below can be preset by entering a number (Presetting
(5700)). The plant diagram is the result of preselection and connected sensors.
Note!
The sensors contained in the respective plant diagram must be connected, thus
ensuring that automatic sensor identification does not select some other plant
diagram. Plant components shown in the form of broken lines are optional.
With certain applications, extension modules (max. 3) must be added to obtain the
required diagram.
