Parameters
7.8.2.1.6 —
Dependent parameter
Monitor receipt of group object "Dew point alarm"
This parameter is only visible if the Channel function parameter has been parameterized with the
Controller channel option.
This parameter is only visible if the Via group object option has been selected for the Dew point alarm
input parameter in the Application parameters parameter window.
Options:
The monitoring of the Dew point alarm group object is activated using this parameter. The regular
reception of the dew point alarm can be monitored using this parameter.
•
Deactivated: The monitoring of the Dew point alarm group object is deactivated.
•
Activated: The monitoring of the group object is active. The dependent parameter Time interval for
cyclical monitoring and the Error: dew point alarm receipt group object are enabled.
7.8.2.1.6.1 —
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: dew point alarm receipt alarm object is changed to alarm and the controller reacts as
if the dew point alarm were active. This means that the controller changes to the Building Protection
operating mode, which results in the closing of the cooling output. As long as the fill level alarm is active,
this mode for cooling cannot be left again. This state remains active until a new value is received in the
group object monitored that clears the alarm.
If the device is changed to the heating mode (on a device that is used for heating and cooling),
the device continues to function as before, without the alarm having any effect, because the alarm only
relates to cooling.
For more information on the dew point, see Application parameters parameter window.
