7.4.1.2.1.1.2.1 Dependent Parameter
Additional-stage cooling
This parameter is visible if, in the Device function parameter, the Controller option is selected and
the Basic-stage cooling parameter is not deactivated.
Options:
The type of application for the additional-stage cooling 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 cooling is deactivated by selecting this option. All dependent
parameters and parameter windows are also deactivated.
• Area cooling (e.g. cooling ceiling): This option should be selected if an area, e.g. cooling ceiling,
is used as the additional-stage cooling.
The Additional-stage cooling control value type parameter is pre-parameterized to PI continu-
ous (0...100%) with the corresponding P and I proportions.
• Free configuration: With this option it is possible to select freely the type of additional-stage
cooling 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 Additional-stage cooling 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: Water cooling coil: This option should be selected if the water heating coil in the
fan coil unit is used as the additional-stage cooling.
The Additional-stage cooling control value typeparameter is pre-parameterized to PI continuous
(0...100%) for Fan Coil with the corresponding P and I proportions.
Dependent parameters:
• Actuate additional-stage cooling via
On the selection of the Fan coil unit: Water cooling 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.
