Technical design
The controller is supplied with 28 basic types of heating plant preprogrammed. They
have been selected to cover the majority of standard applications. Some of them re-
quire extension modules.
When commissioning a plant, the relevant basic plant type must be entered. All associ-
ated functions, terminal assignments, settings and displays will automatically be acti-
vated, and parameters not required will be deactivated.
Precontrol can only be provided by the controller. There are 2 choices:
With mixing valve:
With system pump:

Measuring input B7 for the return temperature can be configured for either minimum or
maximum limitation.
The control of 1 or 2 heating circuits can be provided either by the controller or the
RMZ782 heating circuit module. The available choices are the same with both types of
unit, provided the required connection terminals for the desired auxiliary function are
present.
Please also note the following:
•
If the controller and heating circuit module do not have a sufficient number of config-
urable connection terminals, an additional extension module can be used
•
If the controller is used as a primary controller, the RMZ782 heating circuit module
must be used for the control of the heating circuit
•
A second heating circuit must be controlled with the RMZ782 heating circuit module
•
Measuring input B7 for the return temperature can be configured for either minimum
or maximum limitation
