05.02.2007
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.

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:
