6.2.9 SN: Number of starts
Indicates the number of times the inverter has started the electropump.
6.3 Setpoint menu
From the main menu, press and hold MODE and SET simultaneously until "SP" appears on display (or use the buttons
+ or – in the selection menu).
Buttons + and – enable respectively to increase and decrease the system pressurisation value.
To exit the current menu and return to the main menu, press SET.
This menu enables the user to set the system operating pressure.
The regulating pressure varies between 1.0 and 15 [bar] (14-217 [psi]).
6.3.1 SP: Setting the setpoint pressure
Pressure to apply to the system if the auxiliary pressure regulation functions are not active.
6.3.2 Auxiliary pressure settings
The inverter can vary the set point pressure according to the status of the inputs.
On type M/T and T/T inverters, up to 3 auxiliary pressures can be set for a total of 4 different set points.
On type M/M inverters, one auxiliary pressure can be set for a total of 2 different set points.
For the electrical connections, refer to paragraph 2.3.3, and for software settings, refer to paragraph 6.6.15.
If there are several auxiliary pressure functions active, associated with several inputs, the inverter applies
the lowest pressure of all those activated.
6.3.2.1 P1: Auxiliary pressure 1 setting
Pressure to apply to the system if the auxiliary pressure function is activated on input 1.
6.3.2.2 P2: Auxiliary pressure 2 setting
Pressure to apply to the system if the auxiliary pressure function is activated on input 2.
Not available on type M/M inverters.
6.3.2.3 P3: Auxiliary pressure 3 setting
Pressure to apply to the system if the auxiliary pressure function is activated on input 3.
Not available on type M/M inverters.
The pump restart pressure depends both on the set pressure (SP, P1, P2, P3) and RP.
RP expresses the reduction in pressure, with respect to "SP" (or an auxiliary pressure if activated),
which generates pump start-up.
Exemple:
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].
Entry of an excessively high pressure setting (SP, P1, P2, P3) 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
buttons + 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 buttons + 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.
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.
