KNX Default address for this device is 1.1.1, it can later be modify using ETS software from KNX Association.

7.2.4.2 Available data

The maximum numbers of units that can be controlled using HC-A16KNX are 16. Each unit has 15 communication objects.
These objects are explained as follows:
Address Name
0 Unit-N On/Off
1 Unit-N Mode
2 Unit-N Fan
3 Unit-N Louver Scale
4 Unit-N Louver Auto
5 Unit-N Set Temperature 2 bytes

14 Unit-N Prohibit
N O T E
Address from 9 to 13 will work together. They are used to set the function mode. Only one of them could be activated at the same time.
When one of these bits will be set as 1, the rest will be changed at 0.

Length
1 bit per Shows if HC-A16KNX used the communication with the H-LINK
unit PCB for unit N where N is the address to read.
With value is 1 means that is not possible to communicate with
1 bit
the H-LINK PCB. On 0, communication is working properly.
