Art. No. SC 1000 KNX
i During room temperature control, the controller always uses the adjusted temperature
value to calculate the command values. The adjusted temperature value is transmitted to
the bus via the "Actual temperature" object (see "Transmission of the actual temperature").
The current room temperature can also be displayed optionally in the status line on the
display pages of the main menu level (see page 119-120).
When determining the measured value using combined sensors, the two adjusted values
are used to calculate the actual value.
Transmission of the actual temperature
The determined actual temperature can be actively transmitted to the bus via the
2-byte "Actual temperature" object. The parameter "Transmission when room temperature
change by..." in the parameter node "Temperature measurement" defines the temperature value
by which the actual value must change so that the actual temperature value is transmitted
automatically via the object. Possible temperature value changes lie within a range of
0.1 K and 25.5 K. The setting to "0" at this point will deactivate the automatic transmission of the
actual-temperature.
In addition, the actual value can be transmitted periodically. The "Cyclical transmission of the
room temperature" parameter determines the cycle time (1 to 255 minutes). The value "0" will
deactivate the periodical transmission of the actual temperature value.
Setting the "Read" flag on the "actual temperature" object makes it possible to read out the
current actual value at any time over the bus. It has to be pointed out that with deactivated
periodical transmission and deactivated automatic transmission, no more actual-temperature
telegrams will be transmitted".
Following the return of bus voltage, new programming via the ETS, the object value will be
updated according to the actual temperature value and transmitted on the bus. During room
temperature control, the controller always uses the adjusted temperature value to calculate the
command values. The adjusted temperature value is transmitted to the bus via the "Actual
temperature" object.
