If you activated the temperature curve yesterday, the current day
number of the temperature curve is d6. Therefore, if you activate the
minimum speed curve today, it will effectively be in operation in 4
days, when the current day number of the temperature curve reaches
d10. In the meantime, the fans will run at the specified single
minimum speed (see example 2).
•
If you activated the temperature curve six days ago, the current day
number of the temperature curve is d11. Therefore, if you activate
the minimum speed curve today, it will effectively be in operation the
moment you activate it. In this case, the current minimum speed will
be a value between 10% and 20%.
•
When the minimum speed curve is activated, it will effectively be
operating (i.e. the controller will begin to adjust the minimum speed
according to the specified points of the curve) only when the current
day number of the temperature curve reaches the first day number of
the minimum speed curve.
