Caution
The selection of the type of pump is not applicable for R1 and R2. Various other submenus may be inaccessi-
ble, depending on the additional function selected.
7.2.2. - Type of pump
The type of speed controlled pump must be entered here.
Standard
: Speed control for standard pumps.
0-10V
: Speed control of e.g. High ef
fi
cency pumps by 0-10V signal.
PWM
: Speed control of e.g. High ef
fi
cency pumps by PWM signal.

When selecting this submenu, you may be prompted to save the speed control settings.
This menu contains the settings for 0-10V or PWM pump.
7.2.3. - Pump menu
7.2.3.1. - Pump
In this menu, precon
fi
gured pro
fi
les for various pumps can be selected or can be set in the menu „Manual“ (see „K.1.
- Pump“ on page 57). Please note that individual settings are still possible even when a pro
fi
le has been selected.
7.2.4. - 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 „7.2.1. - Variant“ on page 32 chosen. Purging time can not be applied with PWM or 0-10V output.
Settings range: 5 to 600 seconds / Default setting: 8 seconds
7.2.5. - Sweep time
Sweep time determines the inertia of the speed control to prevent strong
fl
uctuations in temperature. Sweep time is
the timespan for a complete change from minimum to maximum pump speed.
Settings range: 1 to 15 minutes / Default setting: 4 minutes
The indicated percentages are guide values that may vary to a greater or lesser extent depending on the sys-
tem, pump and pump level.
The indicated percentages are guide values that may vary to a greater or lesser extent depending on the sys-
tem, pump and pump level. 100% is the maximum possible voltage/frequency of the controller.
7.2.6. - max. speed
7.2.7. - min. speed
The maximum speed of the pump 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.
Settings range: 70% to 100% / Default setting: 100%
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.
Settings range: („K.1.8. - Speed when „On““ on page 57) to max. speed -5% / Default setting: 30%
