Installed Mitsubishi 3G28 with 2x FJ10VE and 1 x FJ13VE in the bedrooms and MUY-GE24/MSY-GE24 in the living room last week.
Soft humming noise from the 3G28 compressor when running at full power, after rooms reached set temp., the noise is barely noticeable. Everything is cool, the indoor units are quiet and can cool the rooms fast, before 30 Deg C, after 10 mins, temp. dropped by 2 deg c. Default current limit is set at 8.5A can be changed by pushing 5th switch position on SW2 to off.

I'm not an expert here, but 10 mins drop 2 degrees is not very good, IMO. Can any experts here share some thoughts?

Are all units running at the same time?
