Hi,
I filled my system as best as I could but it seems every 10 or more days the fill sensor goes down to 60% from 70% which is the max possible value.
There are no leaks anywhere so I guess this is air bubbles. How could I empty the air from the system? Anyone tried it?
Also what on earth is the deaeration mode or whatever is called. No idea what it does.
Hopefully someone could explain this to me
