12.9 Speed control
(continued)
During this time the pump starts up at its full speed (100%) to ensure reliable
starting. Only after this purging time does the pump run with speed control and
switches to the max. or min. speed, depending on the variant set.
Setting range: from 5 to 600 seconds/default setting: 8 seconds
12.9.3 Sweep time
menu 7.9.3
The control time is used to determine the delay for speed control in order to
avoid large temperature oscillations as much as possible. The time span re-
quired for a complete control process from minimum speed to maximum speed
is entered here.
Setting range: from 1 to 15 minutes/default setting: 4 minutes

The maximum speed of the pump at relay R1 is speci
fi
ed here. During the set-
ting the pump runs at the speci
fi
ed speed and the
fl
ow rate can be determined.
Setting range: from 70 to 100%/default setting: 100%
The indicated percentages are guide values that may vary to a greater
or lesser extent depending on the system, pump and pump stage.
Caution
The minimum speed of the pump at relay R1 is speci
fi
ed here. During the setting
the pump runs at the speci
fi
ed speed and the
fl
ow rate can be determined.
Setting range: from 30 to max. speed -5%/default setting: 50%
The indicated percentages are guide values that may vary to a greater
or lesser extent depending on the system, pump and pump stage.
Caution
This value is the control setpoint for variant 3. If the value at the collector sen-
sor drops below this, the speed is reduced. If it rises above this, the speed is
increased.
Setting range: from 0 to 90°C/default setting: 60°C
