REGULUS - STDC E Controller - www.regulus.eu
F 7.2.5. - PWM On
This signal is needed to turn the pump on at minimum speed.
Setting range: (Solar:) 0 to 50% / Default setting: 10%
(Heating:) 50% to 100%/Default setting: 90%
F 7.2.6. - PWM Max
This determines the output signal for the highest speed of the pump, that is used e.g. during purging or manu-
al operation.
Setting range: (Solar:) 50 to 100% / Default setting: 100%
(Heating:) 0% to 50%/Default setting: 0%
When Output signal 0-10V is selected:
F 7.2.4. - 0-10V Off
This voltage is used when the pump is turned off (Pumps that can detect cable break need a minimum volt-
age).
Setting range: (Solar:) 0.0 to 5.0V / Default setting: 1.0V
(Heating:) 5.0 to 10.0V/Default setting: 9.0V
F 7.2.5. - 0-10V On
This voltage is needed to turn the pump on at minimum speed.
Setting range: (Solar:) 5.0 to 10.0V / Default setting: 10.0V
(Heating:) 0.0 to 5.0V/Default setting: 0.0V
F 7.2.6. - 0-10V Max
This determines the output signal for the highest speed of the pump, that is used e.g. during purging or manu-
al operation.
Setting range: (Solar:) 5.0 to 10.0V / Default setting: 10.0V
(Heating:) 0.0 to 5.0V/Default setting: 0.0V
F 7.2.7. - Speed when “On“
This menu determines the calculated and displayed speed of the pump.
If e.g. 30% is set here and the signal set in „PWM on/0-10V on“ is put out, 30% speed is displayed.
When the signal set in „PWM max/0-10V max“ is put out, 100% speed is displayed. Everything in between is
calculated accordingly.
Setting range: 10 to 90 %/Default setting: 30 %
This function has no in
fl
uence on the regulation, but changes only the speed displayed.
F 7.2.8. - Show signal
Displays the set signal in text and a graphical diagram.
