10.2 Configuration
10.2.1 General
With plant types x–1, x–3, x–5, x–7, DHW heating is activated per default. The DHW
plant type preselected per default depends on the type of plant:
Plant type
Default DHW plant type
H0-x, H2-x, H3-x, H4-x
DHW 2
H1-x
DHW 4
H5-x
DHW 3
H6-x
DHW 6
DHW heating with storage tank is always preconfigured to the RMZ783B DHW module.
For configuration of plant types, refer to section 3.2 “Basic configuration”.
DHW heating can be configured to any of the modules. If the preselected RMZ783B is
replaced by some other module, all settings using type reference RMZ783… via “Extra
configuration” must be reconfigured.
As a basic rule, function blocks can always be activated via “Extra configuration”,
independent of the type of plant. A function block is activated by assigning a pump or
mixing valve output to a terminal.
