Thank you for this manual. Of course I received my own manual but I have glasses and manual text is small so I never read them In computer is something else and if I remember well I found it also myself but you have to know what to look in manual which never been my case.
Thank you for pointing me out at this option now let me see if I understood correctly.
So setting flow temperature lets say between 30 to 45 will fix my problem? For example if temperature in boiler will be > 45 burner will stop and will start when temperature will be < 30

Roughly this is the right direction, but not exactly the optimal resolution of your problem.
The parameter on page 59: "Set flow temperature for external demand" is meant for the case you have no boiler internal temperate regulation. This parameter contains one temperature value only, the system adds an hysteresis by its own.

Look on page 99: There are several Heating mode described, some need additional equipment. I use "Weather-compensated operation" which requires an extra temperature sensor mounted outside the house. The flow temperature setpoint is calculated by use of the selected "Heating curve" to automatically select lower flow temperature when temperature is high outside and raises flow temperature setpoint in cold nights.
