7.3.2. - Purging time
During this time period, the pump is running with full speed (100%) to ensure trouble-
free startup. After this time has passed, the pump is set to speed control and is set to
max. speed or min speed, depending on the speed control variant. Purging time can
not be applied with PWM or 0-10V output.
Settings range: 5 to 600 seconds / Default setting: 8 seconds
7.3.3. - Sweep time
Sweep time determines the inertia of the speed control to prevent strong fl uctuations
in temperature. Sweep time is the time span for a complete change from minimum to
maximum pump speed.
Settings range: 1 to 15 minutes / Default setting: 4 minutes
7.3.4. - max. speed
The maximum speed of the pump is specifi ed here. During the setting the pump runs
at the specifi ed speed and the fl ow rate can be determined.
Settings range: 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. 100%
is the maximum voltage/frequency of the controller.

7.3.5. - min. speed
The minimum speed of the pump at relay R1 is specifi ed here. During the setting the
pump runs at the specifi ed speed and the fl ow rate can be determined.
Settings range:30% to max. speed -5% / Default setting: 50%
7.3.6. - Setpoint
This value is the control setpoint for mode 3 „7.3.1. - Speed control mode“ on page
38 . If the value at the sensor drops below this, the speed is reduced. If it rises
above this, the speed is increased.
Settings range: 0° to 90°C / Default setting: 60°C
