6.2.3.7 0-10V on
The pump needs this voltage in order to switch on.
Setting range: (Solar:) 0.0 to 5.0 V / default: 1.0 V - (Heating:) 5.0 to 10.0 V / default: 9.0 V
6.2.3.8 0-10V max
With this value, you can specify the maximum voltage level for the highest speed of an energy-saving pump which will
be used during purging or manual operation for example.
Setting range: (Solar:) 5.0 to 10.0 V / default: 10.0 V - (Heating:) 0.0 to 5.0 V / default: 0.0 V
6.2.3.9 Rotational speed when ”On”
In this menu, you can change the basis for calculating the rotational speed shown. If, for example, 30% is specified
here, 30% rotational speed will be shown when applying the frequency/voltage under ”PWM On” / ”0-10 V On”. If the
frequency/voltage for ”PWM Max” / ”0-10 V Max” is applied, 100% rotational speed will be shown. Intermediate values
will be calculated accordingly.
Setting range: 10 to 90% / default: 30%
This function does not influence control functions. It merely influences the display on the
status screen.
