7.4.1.1.1.1.5 Dependent Parameter
Actuate basic-stage heating via
This parameter is not visible if the Basic-stage heating parameter is deactivated.
Options:
The way the control value for the basic-stage heating is to be output is set using this parameter.
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.
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.
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)
