The setting "
Send measured value on change
" can be used to set the change on which the sensor
sends its current temperature value. If set to "do not send", the sensor does not send a value,
regardless of the size of the change.
The setting "
Send measured value cyclically
" can be used to set the intervals at which the sensor
sends its current temperature value. The cyclical transmission function can be activated or
deactivated independently of the setting "Send measured value on change". Measured values are
also sent if the sensor has not detected a change. If both parameters are deactivated, a value is never
sent.
In addition, a correction value can be parameterised for the internal sensor under the setting
"
Calibration value for internal sensor
". This correction value serves to increase/decrease the actual
measured value. The adjustment range is from -50 to 50 x0,1K, i.e. the measured value can be
lowered by -5 Kelvin and raised to a maximum of 5 Kelvin. For example, if a value of 20 is set, the
measured temperature value is raised by 2 Kelvin. This setting makes sense if the sensor is installed
in an unfavourable location, such as above a radiator or in a draught area. The temperature sensor
sends the corrected temperature value when this function is activated.
Important: After initial installation/programming the measured value is stable after approx. 30
minutes.
An external sensor can be activated or deactivated via the weighting "
Sensor internal/external
". If
the weighting is set to 100% internal, no external sensor is activated and no communication objects
appear for the external sensor. With any other weighting, an external sensor is activated and the
associated communication objects are also displayed. The "External temperature sensor" object
receives the temperature currently measured by the sensor. The "mixed" temperature is shown in
the display, and this measured temperature value is transmitted via object 80.
Example
:
Weighting: 50% internal / 50% external, internal sensor 25°C, external temperature 15°C
=> transmitted temperature 20°C.
If the "
Messages
" function is activated, two messages can be parameterised. One is the message
function for the lower response value, the "lower message value ", and the other is the upper
response value, the "upper message value".
The two message functions each have a separate communication object.
Principle
:
If the maximum value is exceeded, a "1" is transmitted. If the value falls below it, a "0" is transmitted.
If the value falls below the minimum value, a "1" is transmitted. If it is exceeded, a "0" is transmitted.
