i have a fujitsu reverse cycle AOT/CDS 36/45unit. When the temp exceeds 30 ish degrees, where the time is for the unit. It flashes EE.EE. When it gets to about 5pm, the clock goes back to normal and the unit works. If i turn the unit on in the morning and let it run all day, even if its 40 degrees. It will run all day without stopping. So i gather it is some sort of heat censor problem. I was told to put a sheet of wood over unit as in to stop the sun from reaching the unit, but it made no difference
