Interaction Between the Temperature Curve and the Mini-
mum Speed Curve
•
The minimum speed curve can be activated only if the temperature
curve is already activated
•
All points of the minimum speed curve other than the first one are
automatically given day numbers identical to those specified for the
temperature curve. Only the first point of the minimum speed curve
has an adjustable day number. This day number must be greater or
equal to the day number specified for the first point of the temperature
curve and less than the day number specified for the second point of
the temperature curve (see example 1).
