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.

Fault extension module
Urgent message; must be acknowledged
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.

The inputs of the basic module will be termed RMH760.Xn, those of the extension
modules RMZ… . If 2 identical extension modules are available, they will be termed
RMZ782(1) and RMZ782(2).
After the assignment, following appears: Flue gas temperature sensor N.X4 (N = short
designation of basic module RMH760B).
By assigning input terminal RMH760.X4, the flue gas temperature sensor will be
activated.
For other settings, refer to chapter 6 "Boiler temperature control".
Assignments made or preconfigured can be removed again by using setting "---"
(none).
