8.1 Graphic Display
Using the graphic display it will be possible to navigate in an easy and intuitive menu which will enable you to
check and modify the system operating mode, the enabling of the inputs and the working set-point. It will
also be possible to view the system status and the log of any alarms memorised by the system.
8.2 Navigation Buttons
7 buttons are provided for navigating in the menu: 3 buttons under the display, 3 above it and 1 at the side.
The buttons under the display are called
active buttons , the buttons above the display are called inactive
buttons , and the button at the side is called hidden button .
Each page of the menu is made in such a way as to indicate the function associated with the 3 active buttons
(the ones under the display).
Pressing the inactive buttons (the ones above the display) produces the effect of inverting the graphics and
the buttons that were active become inactive and vice versa. This function also allows the control panel to be
installed “upside down”!
8.3 Warning Lights
Yellow light: System live signal.
If lit, it means that the system is live.
Never remove the cover if the yellow light is lit.
Red light: Warning of an alarm/malfunction present in the system.
If the light is blinking it is a non-blocking alarm and the pump can still be controlled. If the
light is fixed it is a blocking alarm and the pump cannot be controlled.
Green light: Pump ON/OFF signal.
If On, the pump is running. If Off, the pump is stopped.
