W
Write
Object can receive information
T
Transmit
Object can send information
U
Update
Object can request a value from another bus participant. The answer is interpreted as write command and updates the value of the communication object. This is typically
used to request external sensor data after a bus voltage recovery.

Active
Error humidity sensor
notify
don’t notify
If there are no new values provided from the sensor for more than 10 minutes, the sensor failure
will be reported.
No sensor errors will be reported.
Send relative humidity
when changing
Disabled
If change above 1% –
25%
No function.
The new value is sent if the difference between old and new value is above the defined sending
threshold.
Send relative humidity
Disabled
No function.
cyclically
Every minute – once a
day
Cyclic sending of the recent value.
Value
offset
-5% to +5% ppm
The value is adjusted by this offset. A correction might be necessary in different causes. (e.g.
sensor is placed at an unfavorable position, next to a window).
External value
Inactive
No function.
Active
Percentage:
With xx% proportion
Only use external value
The internal and an external value are taken pro rata to calculate an overall value. This value is
relevant for the control and the sending procedure is as defined above.
It only uses the value from the external sensor. The internal (integrated) sensor will not be used.

A switching telegram is sent. There is one object available for every stage.
A priority telegram is sent. There is one object available for every stage.
A percentage value is sent. All steps are sending via one object.
A byte value is sent.All steps are sending via one object.
A scene value is sent. All steps are sending via one object.

Enabled
No function.
When exceeding or falling below a threshold, a defined object is sent.

Disabled
If change above 1% … 25%
No function.
If there is a change, the recent control value is sent.
Send control value
cyclically
Disabled

once a day
No function.
Cyclic sending of the recent control value.
Hysteresis
(symmetrical)
(single-stage, two-
stage, three-stage)
1% to 10%
The hysteresis can prevent a frequent switching for fast and small changing values.
