8.2.2 Values representing chilled ceiling valve actuator
positions
The position of the chilled ceiling valve is mapped to the bus.
The Cooling 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.
Valve positions are available in the following S-mode communication objects:
Cooling surface output (output communication object)
Flags Type
R W C T U
1 0 1 1 0 5.001
DPT_Scaling
If KNX / EIB bus actuators (S-mode) are integrated in DESIGO, the flags must be
checked: delete read access at actuator!
As there are different manufacturers for EIB/KNX bus actuators, the name of the S-
mode communication object varies.
The valve position in LTE mode is transferred as follows:
