Dependent Parameter
Actuate basic-stage heating via
This parameter is not visible if the
Basic-stage heating
parameter is deactivated.
Options:
Internal output A (valve)
Internal output B (valve) (Not for FCC/S 1.4.1.1)
Internal relay output (Not for FCC/S 1.4.1.1)
Group object
The way the control value for the basic-stage heating is to be output is set using this parameter.
Note
Depending on the selection in the
Basic-stage heating
parameter, it may not be possible to select
all options.
Example:
If, in the
Basic-stage heating
parameter, the
Fan coil unit: electric heater (in fan coil unit)
option is
selected, it is not possible to select one of the valve outputs A or B as the output, because an
electric heater cannot be controlled via a valve output. Conversely, the relay output cannot be se-
lected if a water heating type is selected.
•
Internal output A (valve)
;
Internal output B (valve)
;
Internal relay output
: If one of the internal
outputs is selected, the control value is output directly on this physical output where it is con-
verted into the corresponding output signal.
The outputs A and B are used to actuate valve drives, while the relay output is used to actuate
an electric heater.
In parallel to the actuation via the corresponding internal output, the control value is also output
via the related
Status Control value Basic-stage heating
group object.
•
Group object
: If
Group object
has been selected as the option, there is no actuation via any of
the internal outputs, instead the control value is only output on the bus.
The control value is output via the related
Status Control value Basic-stage heating
group ob-
ject.
Note
Depending on the option selected in the
Basic-stage heating
parameter, this parameter may have
a different standard value.
The settings for the exact control parameters are made in the
Temperature controller – Basic-
stage heating
parameter window.
The settings for the actuation of the control values via the valve outputs are made in the related
valve parameter window.
Only FCC/S 1.2.x.1 & 1.3.x.1: If the
Use 6-way valve
parameter has been parameterized with
Yes
, then this parameter is pre-set to
Internal output A (valve)
and cannot be changed.
