86/126
For example, for speed 3:
if
I27
=100%, speed 3 is activated when the valve reaches fully open and is deactivated when the valve closes by 20%
of
I27
, which is 80% of fully open in this case.
Icon turns off if the cooling valve closes again, at which point the fan stops if
I28
=0 or 3. The fan maintains speed 1
if
I28
=1 or 2. The fan maintains speed selected manually if
I28
=4 or 5.
