4.2 Basic configuration
The "Basic configuration" menu is used to make the following settings:
 Select the basic type or of preprogrammed application
 Assign extension modules to the controller position
First, each device is assigned the basic type or a preprogrammed application.
When selecting the plant type, functions are enabled or disabled as required.

4.2.1 Basic types
We distinguish between the following basic types:
 Basic type A (use as a ventilation controller)
Key feature: Controller 1 is a room temperature controller, supply air
temperature controller, or room/supply air temperature cascade controller
 Basic type P (use as a demand-dependent supply air temperature controller)
Key feature: Controller 1 is a demand-dependent supply air temperature
controller
 Basic type C (use as a demand-dependent chilled water controller)
Key feature: Controller 1 is a demand-dependent chilled water flow temperature
controller
 Basic type U (use as a universal controller)
Key feature: Controller 1 is a universal controller
4.2.2 Assign extension modules
The function of the RMU7..B controller can be extended by attaching a maximum
of 4 extension modules.
The following can be connected to each RMU7..B:
1x RMZ785: Extension of inputs
 8 universal inputs
2x RMZ787: Extension of the inputs and outputs
 4 universal inputs, 4 relay outputs
2x RMZ788: Extension of the inputs and outputs
 4 universal inputs, 2 modulating outputs, 2 relay outputs
The extensions can be activated by simply attaching the modules to the controller.
In addition, the position of the extension module must be set on the controller.

 Disconnect the system from power prior to attaching an extension module
 A standard application in the controller can also contain connections to the
extension modules. The relevant functions are only active if the respective
extension module is connected and activated
