Dimensionless
- Represents mass flow of air in the appliance.
- Can also represent gas flow in the appliance if the Lambda
S16
value is held constant.
- When linking this value to fan speed, consideration must be
given to relative changes in air density.

Bit 0: True = if new curve point is added, it will replace
another existing point. 0 = a new point will be added to the
curve.
Bit 1: True/False = the fuel/air curve commissioning mode
is active/inactive.
Bit 2: True = a fuel/air curve maximum point already exists.
Bit 3: True = point commissioning is currently active.
Bit 4: True = a fuel/air curve minimum point already exists.
U16
Bit 5: True = an initial fuel/air curve already exists.
Bit 6: True = a fuel/air curve point is being sampled.
Bit 7: True = the fuel/air curve is locked.
Bit 8: True = the loaded fuel/air curve data is OK and can
be stored. Updated when the fuel/air curve is unlocked for
editing.
Bit 9: True = a new fuel/air curve point has been saved.
X-coordinate of CORRECTION fuel/air curve, S1 sensor
value.
