Frequent defrost Daikin FTXL35

[dkt850]

Anyone know the precise condition for defrost in the Daikin FTXL35 heatpump?
They seem to run defrost every 30 min without any reason, even no ice and low load.

I've found this information earlier. It would be of great help to know for what outdoor temp and for what exchanger temp the condition is set.
