7.4.1.1.1.1.2 Dependent Parameter
Basic-stage cooling
The following description applies in the case that the Controller option in the Device function pa-
rameter.
Options:
The type of application for the basic-stage cooling is selected with this parameter. The controller is
pre-configured based on this selection and can be used for the selected application.
• Deactivated: The basic-stage cooling is deactivated by selecting this option. All dependent pa-
rameters 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 basic-stage cooling.
The Basic-stage cooling control value type parameter is pre-parameterized to PI continuous
(0...100%) with the corresponding P and I proportions.
• Free configuration: With this option it is possible to select freely the type of basic-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 Basic-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 basic-stage cooling.
The Basic-stage cooling control value type parameter is pre-parameterized to PI continuous
(0...100%) for Fan Coil with the corresponding P and I proportions.
Dependent parameters:
• Additional-stage cooling
• Type of heating/cooling system
• Heating/Cooling changeover
• Use 6-way valve (only FCC/S 1.2.x.1 / 1.3.x.1)
• Actuate basic-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.
