Use to check the noise of motor and
controller ’s interference to the
surroundings. A high carrier makes a
low motor noise, but leads to a big
temperature rise and interference.
Should not be altered if unnecessary.

In order to balance and prolong the
pump service life to set the parameter,
unit: hour. When the parameter is set
to 0.0, it means no alteration.
