The user setpoint which provided through KNX bus is automatically changes without any external input.

Additionally, is there any configuration settings to be done on the Fujitsu indoor unit PCB to accept setpoint only from KNX bus.

Fujitsu Indoor : ARGG24CLTA-U

  Hi!

  in the ticket this was the result:

  We noticed that the problem occurs when the AC Setpoint is calculated lower than the minimum Set point accepted by the Fujitsu. This is due to the Ambient temperature sensors reading difference. (The AC and KNX sensor.) 
   

  in normal conditions, the difference will not be that high.
