Room temperature controller | Controller status
gram will be transmitted via the object "Heating status object". The signal telegram is
only reset when the command value is "0" ("0" telegram is transmitted). The same
applies to the object "Cooling status object".
The signal objects can be enabled by the "Heating status object" or "Cooling status
object" parameters in the parameter branch "Room temperature controller x -> RTCx
- General -> Status". The control algorithm controls the signal objects. Please note
that the command values are recalculated every 30 s, thus updating the signal ob-
jects.
Controller status
The room temperature controller can transmit its current status to the KNX. A choice
of data formats is available for this. The parameter "Status" in the parameter node
"RTCx - General -> Enabled functions" enables the parameter page "Status". The dif-
ferent status objects can be activated there individually.
– The KNX-compliant controller status feedback is harmonised on a manufac-
turer-independent basis.
– The objects "Controller status RHCC - KNX compliant", "Controller status RTC
- KNX compliant" and "Controller status RTSM - KNX compliant" display ele-
mentary basic functions of the controller.
– These objects are supplemented by the two 1-byte objects "Operating mode
status" and "Forced operating mode status" (DPT 20.102), which report back
the operating mode actually set at the controller. The last two objects men-
tioned above are generally used to enable controller extensions to display the
controller operating mode correctly in the KNX compliant status display.
Therefore, these objects should be connected with controller extensions if the
KNX-compliant status feedback is not configured.
