Dependent Parameter
Basic-stage heating
The following description applies in the case that the
Controller
option has been selected in the
Device function
parameter.
Options:
Deactivated
Convector (e.g. radiator)
Area heating (e.g. floor)
Electric heater (in room)
Free configuration
Fan coil unit: electric heater (in fan coil unit)
Fan coil unit: Water heating coil
The type of application for the heating stage is selected with this parameter. The controller is pre-
configured based on this selection and can be used for the selected application.
•
Deactivated
: The heating stage is deactivated by selecting this option. All dependent parame-
ters 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 heating stage.
The
Basic heating stage control value type
parameter is pre-parameterized to
PI continuous
(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 heating stage.
The
Basic heating stage control value type
parameter is pre-parameterized to
PI continuous
(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 heating stage and for this heater the fan does not need to run as well in operation.
The
Basic heating stage 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 heating stage 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 heating stage 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 heating stage and the fan must therefore also run in operation.
The
Basic heating stage 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 heating stage.
The
Basic-stage heating 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 heating
•
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 heating via
Note
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.
