•
When the minimum speed curve is activated, it will effectively be
operating (i.e. the controller will begin to adjust the minimum speed accord-
ing 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.

•
If you activated the temperature curve yesterday, the current day
number of the temperature curve is d6. Therefore, if you activate the mini-
mum 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%.
