Frequent defrost Daikin FTXL35
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.

Conditions for Starting DefrostThe starting conditions must be made with the outdoor air temperature and heat exchangertemperature. Under the conditions that the system is in heating operation, 6 minutes after thecompressor is started and more than 44 minutes of accumulated time pass since the start of theoperation or ending the defrosting.Conditions for Canceling DefrostThe judgment must be made with heat exchanger temperature. 4c-12c

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.
