• Signal lamps/LEDs
(layout Fig. 1, item 4)
Green LED run signal indicates the system's operational readiness. It lights up even if no pump is running.
Red LED for low water indicates by going on continuously whether the system has shut down after the detection
of a low water level. Flashing indicates that a low-water signal applied; however, there is currently no fault. Flashing
stops when the fault is acknowledged by turning the rotary knob.
Red LED for overpressure indicates a fault if the system has shut down due to a system pressure being too high. If this
light flashes, that indicates a previous overpressure fault that no longer applies. Flashing stops when the fault is
acknowledged by turning the rotary knob.
Green LED for run signal of pumps (pump status) indicates that at least one pump is being controlled
Red LED for pump malfunction (pump status) indicates that a fault is indicated by at least one pump. This LED does
not light up in the event of a sensor fault or controller fault.
4.2.2 Menu structure
The complete menu structure consists of the fol-
lowing elements:
• Standard display
• Operating modes menu
• Controller setting menu (with operation indicator
and error memory)
The current system pressure is displayed on the
standard display . In addition, the symbol
indicates whether standby pump mode was set.
A flashing symbol indicates that no standby pump
is available (e.g. due to a pump fault).
(1) By briefly pressing (< 2 seconds) the red rotary
knob, the standard display switches to the
Operating modes menu . In this menu, the
corresponding pump (P1, P2, P3, P4) is selected
by turning the rotary knob. Only the number of
pumps that were configured via the DIP switches
appears on the display (see Section 4.2.3).
After selecting the pump, this selection must
be confirmed by briefly pressing the rotary knob.
Then, the current operating mode of the pump
is displayed:
(The key symbol indicates any error
message of the pump. It also indicates the
“Ext.Off” status or a sensor fault.)
The operating mode of the pump can be set by
turning the rotary knob to the left or right.
Then, pressing it briefly takes you back to the
standard display.
(2) By continuously pressing (> 2 seconds) the red
rotary knob, the standard display switches back
to the
Controller setting menu . A menu item
(Tab. 1) can be selected by turning the knob.
To be able to change the values, the rotary
knob needs to be pressed briefly at the corre-
sponding point of the menu. That displays the
previously set parameter on the display and it
can be adjusted by turning the rotary knob.
Pressing the rotary knob briefly takes you back
to the selection of menu items and pressing it
continuously takes you back to the standard
display.
