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
required 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 specified here. During the
setting the pump runs at the specified speed and the flow 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 specified here. During the
setting the pump runs at the specified speed and the flow 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 sensor 1 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
