Display
All information and settings can be queried using the digital
potentiometer
display
. If a setting is to be changed, the regulator is
adjusted until the corresponding setting appears on the display.
Now press the
select / cancel
button. The value last saved will start to
blink. The digital potentiometer
display
can now be used to change
the setting. Quick turns will change the values more rapidly, while
slow turns make it possible to make more precise changes. Once the
desired value has been reached, use the
select / cancel
button to
confirm. The value will stop blinking and be stored. Check all values
prior to commissioning. The display will automatically return to the
default setting after 20 seconds.
The operating hours and pump starts are counted
continuously, it is not possible to adjust or reset them.
4.2
Operating elements
Pressing the digital potentiometer will query all settings as
well as error messages, operating hours, number of pump
starts and motor current. Moreover, the settings are
performed using the digital potentiometer. If the knob is not moved
for more than 20 seconds, then the display will jump back to the
default setting. (see above, Configuration chapter)
Pressing this button will confirm the errors overcurrent,
pump without load and thermal error 2 after removal of
the cause. In the event that an error should continue to be
present, then only the common error report relay and the piezo
buzzer will be shut off. This also applies to all other errors and the
high water alarm. Settings can still be changed using the button.
Pressing this button will manually put the pump into
operation. The green LED will blink. If the pump is being
run via the manual function, then it will automatically shut off after
2 minutes and the green LED will flash irregularly.
The automatic and manual operation are shut down using
this button. The green LED is off.
The pump is switched based on the level. The green LED is
lit continuously.
If power is interrupted during manual mode, then the
control system will return to the automatic mode. The
operation modes “Auto” and “0” are stored in non-volatile
memory.

Display
In the upper area of the display, there is a bar graph for the level (L)
and two bar graphs for the current of the pumps (I). In the display’s
basic setting, the level and the operating hours are additionally
displayed in numbers below the bar graph displays. If the pump is in
operation, the motor current will be displayed. If any disruptions
occur, then they will be displayed alternatingly on the display’s
bottom line.

Automatic deactivation of the background
lighting:
If no further settings are performed on the device, the background
lighting switches off automatically after 30 seconds. As soon as the
rotary switch or one of the pushbutton switches is actuated, the
background lighting switches on again. This function can be disabled
via the menu and then the background lighting remains switched on.
