When selecting the plant type, an extension module will automatically be preconfigured,
if required. This can be changed in the basic configuration.
The assignment of functions to the basic module and the extension modules is not
prescribed. Relay outputs for 3-position applications are preconfigured to the controller
or the extension module type RMZ782B or RMZ783B.
The following types of extension modules can be connected to each RMH760B:
• Heating circuit module RMZ782B with 3 inputs and one modulating output plus 3
relay outputs (one relay with changeover contact). It is also possible to activate 2
relay outputs for the control of 3-position actuators with an RC unit
• DHW module RMZ783B with 4 inputs, one modulating output and 5 relay outputs (2
relays with changeover contact). It is also possible to activate 2 relay outputs for the
control of 3-position actuators with an RC unit
• Universal module RMZ787 with 4 inputs and 4 relay outputs (one relay with change-
over contact)
• Universal module RMZ789 with 6 inputs, 2 modulating outputs and 4 relay outputs (2
relays each for the control of 3-position actuators with RC units can be activated)
The extensions can be activated by configuring them at a free position of the controller.
The controller can accept a maximum of 4 extension modules. Of module types
RMZ783B (DHW) and RMZ787 (universal), a maximum of one module can be used, of
heating circuit module type RMZ782B and universal module type RMZ789, a maximum
of 2 of each.
3.2.6 Basic configuration
Configuration of the controller is always started by defining the plant type. Based on the
selected plant type, the required types of extension modules are to be selected and will
be displayed on the following lines:
Main menu > Commissioning > Basic configuration
Operating line
Plant type
Position 1
Position 2
Position 3
Position 4
--- = no module configured
On operating line "Plant type", the plant type is to be entered or will be displayed.
Operating lines Position 1...Position 4 display the type of extension module required. On
these operating lines, the presettings can be changed or complemented. When chang-
ing a predefined extension module, all settings relating to these extension modules and
made via "Extra configuration" must be adapted.
