• “N.“ in the tables denotes “controller“
• If required, additional inputs and outputs (e.g. flue gas temperature sensor, operating
mode relay, circulating pump) can be assigned to the free inputs and outputs via “Ex-
tra configuration”
• The inputs and outputs can be checked with the help of menu Extra configuration > … >
Inputs (or Outputs)
• It is possible to reconfigure or remove preconfigured inputs and outputs
Example: When removing the second burner stage (“---“ in place of N.Q4, for exam-
ple), the 2-stage burner becomes a 1-stage burner.
The configuration diagram shows the types of extension modules required.
Also shown are the inputs and outputs preconfigured in the extension modules. For
plant type H4-5, extension modules RMZ782B(1), RMZ782B(2) and RMZ783B are
used as standard. This can be viewed on the Basic configuration menu, operating lines
Position 1, Position 2 and Position 3.
The type of extension modules used can be changed, but in that case, all inputs and
outputs of the changed module must be reconfigured.

A maximum of 4 extension modules can be connected to the RMH760B.
Prior to attaching an extension module, the plant must be disconnected from power.
The order in which the extension modules are fitted is not mandatory but must corre-
spond to the setting made on the controller.
