I have a villa project with Daikin Concealed Ceiling Units.https://www.daikinmea.com/en_us/product-group/DMEA-concealed-ceiling/dmea-FDMRN-AV1K.html
I was checking different gateways(Control4 and KNX) to control this units.but still I can't find any solution.we are using KNX thermostatic keypads integrated C4 controller in this project.
Intesis and Airzone interface gateways are not compatible.
The connection port of the indoor unit is S21. these units belongs to Daikin Middle East & Africa.
If anyone has a solution please let me know guys.☺️
