Reduce bus load
Values representing radiator valve actuator positions
The position of the radiator valve is mapped to the bus.
The Heating surface output communication object must NOT be used for applications
for thermal valve actuators to control KNX/EIB valve actuators. With these applications,
the communications objects have theoretical valve positions only.
In S-mode, the following communication object is used for this purpose:
Heating surface output (output communication object)
R W C T U
1 0 1 1 0 5.001
Since EIB/KNX bus actuators are available from a variety of manufacturers, the name
of the S-mode output communication object varies accordingly.
If KNX / EIB bus actuators (S-mode) are integrated in DESIGO, the flags must be
checked: delete read access at actuator!
In LTE mode, the radiator position is transmitted as follows:
Heating surface output (output)
In LTE-mode, where directly connected actuators are used rather than bus valve
actuators, the bus load can be reduced by disabling LTE communication for these
outputs (see also page 118).
