5.4.20.1 Second speed function setting
Settings for second speed can be changed.
CAUTION
There is an endurance limit of setting changes (no more than 24 times per day for about ten years).
If this limit is exceeded, it not only may become impossible to change the setting but can also cause
pump failure. Do not make setting changes in excess of this endurance limit.
