6.3.4 P3: Auxiliary pressure 3 setting
Pressure to apply to the system if the auxiliary pressure function is activated on input 3.
6.3.5 P4: Auxiliary pressure 4 setting
Pressure to apply to the system if the auxiliary pressure function is activated on input 4.
NOTE 1: If there are several auxiliary pressure functions active, associated with several inputs, the inverter
applies the lowest pressure of all those activated.
NOTE 2: The pump restart pressure depends both on the set pressure (SP, P1, P2, P3, P4) and RP.
RP expresses the reduction in pressure, with respect to "SP" (or an auxiliary pressure if activated), which
generates pump start-up.
Example: SP = 3,0 [bar]; RP = 0,5 [bar]; no auxiliary pressure function active:
During normal operation, the system pressure is set at 3.0 [bar].
The electric pump is restarted when the pressure falls below 2.5 [bar].
CAUTION:
entry of an excessively high pressure setting (SP, P1, P2, P3, P4) with respect to the pump
output specifications, may cause false errors of water failure (BL); in this case lower the pressure setting or
use a pump suited to system requirements.
6.4 Manual menu
From the main menu, press and hold “SET" & “+” & “-“ simultaneously until “FP” appears on display (or use
the b or – in the selection menu).
This menu enables the display and modification of various configuration parameters. The MODE button
enables the user to scroll through the menu pages, while b and – enable respectively to increase
and decrease the value of the parameter concerned. To exit the current menu and return to the main menu,
press SET.
NOTE: In manual mode, regardless of the parameter on display, the following commands are enabled:
Temporary start-up of electric pump
When the buttons MODE and - are pressed simultaneously, the pump is started up at the frequency FP and
this operating status remains while the buttons are pressed.
When the pump ON or pump OFF command is activated, the relative notification is shown on display.
Pump start-up
When the buttons MODE and + are pressed simultaneously for 2 seconds, the pump is started up at the
frequency FP. This operating status remains until SET is pressed. When SET is pressed again, the user
exits the manual mode menu.
When the pump ON or pump OFF command is activated, the relative notification is shown on display.
Inversion of direction of rotation
When the buttons SET and - are pressed simultaneously for 2 seconds, the pump changes direction of
rotation. The function is also enabled when the motor is running.
6.4.1 FP: Test frequency setting
This displays the test frequency in [Hz] and enables modification by means of the buttons “+” and “-“.
The default value is FN – 20% and can be set between 0 and FN.
6.4.2 VP: Display of pressure
System pressure measured in [bar] or [psi] depending on measurement system selected.
