Parameters
7.8.2.1.4 —
Dependent parameter
Monitor receipt of group object "Control value"
This parameter is only visible if the Device function parameter has been parameterized with the
Controller option, that is the device is operated with a controller.
Options:
With the monitoring of the Control value group object, the device can monitor the regular reception of the
control value in the actuator mode. If the control value is not received, a pre-defined control value can be
set that is used in the currently active type of operation (heating or cooling). With this monitoring it is
possible to use a pre-defined control value on the failure of the device that sets the control value,
until a new value is received.
•
Deactivated: The cyclic monitoring of the Control value group object is deactivated.
•
Activated: The cyclic monitoring is activated, the following dependent parameters are also displayed.
7.8.2.1.4.1 —
Dependent parameter
Time interval for cyclical monitoring
Options:
The monitoring time within which the group object must be received is specified using this parameter.
Otherwise the Error: control value receipt alarm object is changed to alarm and the value set in the
Control value after exceeding monitoring time parameter applies.
7.8.2.1.4.2 —
Dependent parameter
Control value after exceeding monitoring time
Options:
The control value set here is valid as soon as a control value has not been received by the device within
the monitoring time parameterized. The value set here remains active until a control value has been
received again.
