When using Position 1 in this example, extension module RMZ782B is selected.
Then, at position 2, module type RMZ787 is selected.
Positions 3 and 4 remain blank. They use setting “---“ and are confirmed with the OK
knob, which means that they are left blank.
During the configuration, the ESC button can be pressed to return to the previous
setting.
Once the configuration is started, it cannot be stopped! Configuration
must
be com-
pleted until the following message appears:
Caution!
New configuration
ESC
OK
Here, the configuration can be aborted.
Functions can be assigned to additional inputs and outputs via “Extra configuration”. If
the maximum number of extension modules do not suffice, parts of the plant must be
wired and configured to a second RMH760B.
If the extension modules actually used and their positions do not accord with the values
entered, a fault status message
Fault extension module
will be delivered.
In the case of an incorrectly configured extension module, some other fault status
message may also be displayed because that consequential fault has the higher priority
than fault status message 7101. It is therefore of advantage to have all pending faults
displayed.

In the event of fault, the LEDs on the extension modules flash. If everything works
correctly, the LEDs are lit.
3.3
Extra configuration
3.3.1 General
By configuring additional inputs and outputs, adaptations to the hydraulic circuit can be
made, and extra functions and function blocks can be activated.
Depending on the selection of plant type, a number of function blocks have already
been activated (e.g. boiler, main controller, DHW, heating circuit, etc.).
Also refer to subsection 3.2.4 "Use of the configuration diagrams".
When configuring an output, the relevant function block will automatically be activated.
The plant’s hydraulic circuit is determined by the basic configuration and the extra
configuration of plant components, such as pumps and mixing valves, etc. In most
cases, the configured outputs are decisive for the plant’s hydraulics.
Additional inputs and outputs can activate various functions. A description of these
functions is given with the relevant function block.
