This option is only available if the following settings have been selected on the
Operation parameter page:
Parameter page
Operation
Here the set value is changed directly by sending the required shift to object 0.
To do this, the difference (where applicable as a negative value) is sent to object 0 in
EIS5 format.
The shift always relates to the
setting wheel) and not to the current set value.
Example Basic set value 21°C:
If the value 2.00 is set to obj. 0, the new set value is calculated as follows:
21°C + 2.00K = 23.00°C.
To then bring the set value to 22°C, the difference is sent again to the parameterised
basic set value (here; 21°C), in this case 1.00K (21°C + 1.00K = 22°C)
5.3.3 S et the presence object with set value shift
4 0 B
The RTF/A 1.1 allows you to set the presence object solely by increasing the set
value on the setting wheel. This means that the device changes to comfort mode and
the room temperature is brought to a comfortable level.
This function can be activated using the For set value increase on the setting wheel
→ Set presence object parameter on the Operation parameter page
No reset is carried out due to the set temperature reducing.
Exit comfort mode.
