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").
When determining the measured value using combined sensors, the two adjusted values
are used to calculate the actual value.
i
The object value of the communication object No. 80 (s.measured value for temperature) is
the determined and corrected temperature value of the integrated sensor (self-heating).
The parameter "Calibration of internal temperature sensors" is added to the object value as
offset.
i
The object value of the communication object No. 23 (actual temperature) is the read out
value of the communication object No. 80 (S.measured value for temperature), to which the
parameterised calibration value was already applied. The application of a parameterised
evaluation and weighting might possibly still take place. This temperature value serves as
the actual temperature for the room temperature controller function
i
The object value of the communication object No. 59 (actual temperature non-calibrated) is
the read out value of the communication object No. 80 (S.measured value for temperature)
without temperature calibration. This value is the actual room temperature measured by the
internal temperature sensor.
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 "Sensor -> 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. 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.
If, when using a separate KNX sensor, no temperature value telegram of the separate sensor
was received, only the value formed by the internal sensor is transmitted. If the separate sensor
is used exclusively, the value "0" is in the object after a reset. For this reason, the separate KNX
temperature sensor should always transmit the current value after a reset.
