When it comes to the 0-10V FCU application , The FCU controller is not available in the current KNX product range , but by using the latest TC903 or TC907 the integration is possible with the help of SpaceLYnk/Wiser for KNX through Modbus . Attached is the modbus profile for TC90x .
Additional to that , if the system needs to be controlled from the KNX Multi touch Pro , some small scripting is also required to match the Fan speed , Auto and OFF, Attached is the Project Backup

Thank you, Hashim for the integration guidance. We are going to add a profile to next firmware release together with other in queue.

does the system alredy have the AC fan speed interlocked internally?
looking at the json file it has 3 different modbus registers for the ac fan speed status, each with on/off value..
is it possible for them all to be "on" ?? or does the product update the other registers automatically to off ?
"name": "Fan speed Status - High", "bus_datatype": "bool", "type": "coil", "address": 4, "writable": 0 , "value_custom": {"0": "Off", "1": "On" }},
{ "name": "Fan speed Status - Medium", "bus_datatype": "bool", "type": "coil", "address": 5, "writable": 0, "value_custom": {"0": "Off", "1": "On" } },
{ "name": "Fan speed Status - Low", "bus_datatype": "bool", "type": "coil", "address": 6, "writable": 0, "value_custom": {"0": "Off", "1": "On" } }
asking for my own info when I need to create jsons for other products..
also noted you typo, I think this should read as 'units'........ not "uints" throughout the json
"uints": "°C" },
some newer people might get confused seeing it as unsigned integer instead of a spelling error.

Hi @Coppo
The lines you mentioned are the one which are reading coils , this is like a status feedback object in KNX . The register which is used to change the fan speed are as follows . There is an interlock between the 3 output in TC907
{ "name": "Fan Mode", "bus_datatype": "uint16", "type": "register", "address": 5, "writable": true, "value_custom": {"0": "High", "1": "Medium", "2": "Low", "3": "Auto" } },
Thank you for pointing out the typo in the file ,updated above is the new .json. The typo "uints": "°C" as well as "uints": "V" are updated . There were no error in the test and works well with the same but, the correct one is as you have mentioned .

Hi Hashin,
thnak you for confirming my question that the TC907 has intenral interlocking on those registers, much thanks.
just thought it looked odd as i would normally expect to see it exactly like you posted
{"0": "High", "1": "Medium", "2": "Low", "3": "Auto" } },
all good. much thanks. I will add it to my json library.
we re-use these modules in AU for the Clipsal 5500NAC / SE LSS5500NAC automation controller gateways.
