Monitor Menu

Keep the "SET" and "-" (minus) keys pressed simultaneously for 2 sec from the main menu to access the MONITOR MENU.
In this menu, by pressing the MODE key, the following values are displayed in sequence.
5.2.1 CT: Display contrast
Adjusts the display contrast
5.2.2 BK: Display brightness
Adjusts the backlighting of the display on a scale from 0 to 100.
5.2.3 TK: Backlight switch-on time
Sets the time that the backlight is lit since the last time a key was pressed.
Values allowed: '0' always off; from 20 sec to 10 min or 'always on'. With the backlight setting always ON, the display
shows "ON". When the backlight is off, the first time any key is pressed has the sole effect of restoring the backlighting.
5.2.4 TE: Dissipator temperature display

Setpoint Menu

From the main menu, hold down simultaneously the "MODE" and "SET" keys until "SP" appears on the display.
The + and – keys allow you respectively to increase and decrease the plant boosting pressure. Press SET to leave this
menu and return to the main menu. The range of adjustment is 1-5 bar (14-80 psi).
5.3.1 SP: Setting the setpoint pressure
Pressure at which the system is pressurised
The pump restarting pressure is linked not only to the set pressure SP but also to RP. RP expresses the
decrease in pressure, with respect to "SP" caused by the pump starting.
For example: SP = 3 bar (43.5 psi); RP = 0,3 bar (4.3 psi);
During normal operation the system is pressurised at 3 bar (43.5 psi). The electropump restarts when the pressure falls
belowai 2,7 bar (39.2 psi).
Setting a pressure (SP) that is too high for the pump performance may cause false water lack errors BL; in these
cases lower the set pressure.
Attention: the setting of particular values of this parameter with relation to the system may help create situations
of risk due to high water temperatures being reached inside the pump (see Warnings, Chap. 2).

Manual Menu

In manual operation, the sum of the input pressure and the maximum pressure that can be supplied must not
be greater than 6 bar.
From the main menu, hold down simultaneously the "SET" and "+" and "-" keys until the manual menu page appears. The
menu allows you to view and modify various configuration parameters: the MODE key allows you to scroll through the
menu pages, the + and – keys allow you respectively to increase and decrease the value of the parameter concerned.
Press SET to leave this menu and return to the main menu.
Entering the manual menu by pressing the SET + - keys puts the machine into forced STOP condition. This function can
be used to force the machine to stop.
In the main menu, irrespective of the parameter displayed, it is always possible to perform the following controls:

Temporary starting of the electropump.

Permanent pump start up.

Modification of number of pump rotations in manual mode.
Pressing the MODE and + keys at the same time causes the pump to start at speed RI and this running status remains as
long as the two keys are held down.
When the pump ON of pump OFF command is given, a communication appears on the display.
Starting the pump
Holding down the MODE - + keys simultaneously for 2 sec. causes the pump to start at speed RI. The running status
remains until the SET key is pressed. The next time the SET key is pressed the pump leaves the manual menu.
When the pump ON of pump OFF command is given, a communication appears on the display.
In case of operation in this mode for more than 5' without the presence of hydraulic fluid, the machine stops, giving the PH
alarm.
Once the PH error condition is no longer present, the alarm will be reset automatically only. The reset time is 15'; if the PH
error occurs more than 6 times consecutively, the reset time increases to 1h. Once it has reset further to this error, the
pump will remain in stop status until the user restarts it using the "MODE" "-" "+" keys.
