Setting the "Largest command value" function
General valve outputs -> Largest command value
Transmit
The largest command value determined by the heating actuator is actively transmit-
ted to the bus. This parameter decides when a telegram is transmitted via the
"Largest command value" object.
This parameter is visible only if the "Largest command value" function is enabled.
On change: A telegram is only transmitted when the largest command value
changes.
Cyclical: The actuator only transmits the "Largest command value - Status" telegram
cyclically. The cycle time is defined globally for all feedback on the parameter page
"General".
On change and cyclical: The actuator transmits the "Largest command value -
Status" telegram when the object value changes and also cyclically.
Transmit on change by
Here, the change interval of the largest command value for automatic transmission
is defined. The actuator only transmits a new telegram value when the largest com-
mand value has changed by the interval preset here since the last transmission op-
eration.
This parameter is visible only if the "Largest command value" function is enabled.
Detect external largest command value
via object
The actuator is able to evaluate an external largest command value (e.g. from an-
other heating actuator). The local heating actuator monitors the external telegram
with its own active constant command values and outputs the largest of all command
values via the object "Largest control value - Status".
This parameter will enable the object "Largest command value - External" in the
"yes" setting. It is only available when the "Largest command value" function is en-
abled.
