* The maximum rpm that the controller is to use as a set point.
** The maximum rpm that the fan is actual able to run.
The maximum actual rpm can be lower than the maximum rpm set point. This is because the fan is not able to
reach the maximum rpm set point, due to the unit's resistance. The tolerance varies according to the design of
each specific unit. The relation between the maximum rpm set point and the maximum actual rpm is given in this
table. This table applies also to the service and "Schornsteinfeger" function of the boiler.
