7.4.1.1.1.1.1.1 Dependent Parameter
Additional-stage heating
This parameter is visible if, in the Device function parameter, the Controller option is selected and
the Basic-stage heating parameter is not deactivated.
Options:
The type of application for the additional-stage heating is selected with this parameter. The con-
troller is pre-configured based on this selection and can be used for the selected application.
• Deactivated: The additional-stage heating is deactivated by selecting this option. All dependent
parameters and parameter windows are also deactivated.
• Convector (e.g. radiator): This option should be selected if a convector, e.g. a radiator, is used
as the additional-stage heating.
The Additional-stage heating control value type parameter is pre-parameterized to PI continu-
ous (0...100%) with the corresponding P and I proportions.
• Area heating (e.g. floor): This option should be selected if an area, e.g. floor heating, is used as
the additional-stage heating.
The Additional-stage heating control value type parameter is pre-parameterized to PI continu-
ous (0...100%) with the corresponding P and I proportions.
• Electric heater (in room): This option should be selected if an electric heater in the room is used
as the additional-stage heating and for this heater the fan does not need to run as well in opera-
tion.
The Additional-stage heating control value type parameter is pre-parameterized to 2-point 1 bit
(On/Off).
• Free configuration: With this option it is possible to select freely the type of additional-stage
heating and also the type of control. This option can be selected if the type of application is not
entirely clear or if specific adjustments are necessary.
The Basic-stage/Additional-stage heating control value type parameter is pre-configured to PI
continuous (0...100%), however it is possible to select freely between all control types.
• Fan coil unit: electric heater (in fan coil unit): This option should be selected if an electric heater
in the fan coil unit is used as the additional-stage heating and the fan must therefore also run in
operation.
The Additional-stage heating control value type parameter is pre-parameterized to 2-point 1 bit
(On/Off).
• Fan coil unit: Water heating coil: This option should be selected if the water heating coil in the
fan coil unit is used as the additional-stage heating.
The Additional-stage heating control value type parameter is pre-parameterized to PI continu-
ous (0...100%) for Fan Coil with the corresponding P and I proportions.
Dependent parameters:
• Actuate additional-stage heating via
On the selection of the Fan coil unit: electric heater or Fan coil unit: Water heating coil options,
the fan follows the valve control value for this stage if the automatic mode is active.
On the selection of the Free configuration option, this can also be set via a parameter.
