The auxiliary setpoints can be used only through the control unit.
7.3.2.1 - P1: Setting the auxiliary setpoint 1
Pressure at which the system is pressurised if the auxiliary setpoint func
-
tion is activated on input 1.
7.3.2.2 - P2: Setting the auxiliary setpoint 2
Pressure at which the system is pressurised if the auxiliary setpoint func
-
tion is activated on input 2.
7.3.2.3 - P3: Setting the auxiliary setpoint 3
Pressure at which the system is pressurised if the auxiliary setpoint func
-
tion is activated on input 3.
7.3.2.4 - P4: Setting the auxiliary setpoint 4
Pressure at which the system is pressurised if the auxiliary setpoint func
-
tion is activated on input 4.
The pump restarting pressure is linked not only to the set pressure
(SP, P1, P2, P3, P4) but also to RP. RP expresses the decrease in
pressure, with respect to “SP” (or to an auxiliary setpoint if activat
-
ed), caused by the pump starting.
For example:
SP = 3,0 [bar]; RP = 0,5 [bar]; no active auxiliary setpoint function-
During normal operation the system is pressurised at 3.0 [bar].
The electropump restarts when the pressure falls below 2.5 [bar].
Setting a pressure (SP, P1, P2, P3, P4) that is too high for the
pump performance may cause false water lack errors BL; in
these cases lower the set pressure
7.4 - Manual Menu
From the main menu, hold down simultaneously the “SET” and “+” and
“-“ keys until the manual menu page appears (or use the selection menu
pr or -).
The menu allows you to view and modify various configuration parame
-
ters: 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.
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’ with no flow of liquid,
an alarm overheating alarm will be triggered, with the error PH shown on
the display.
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 fur
-
ther to this error, the pump will remain in stop status until the user restarts
it using the “MODE” “-” “+” keys.
7.4.1 - Status:
Displays the pump status.
7.4.2 - RI: Speed setting
Sets the motor speed in rpm. Allows you to force the number of revolutions
at a predetermined value.
