RT: Setting the direction of rotation
If the direction of pump rotation is incorrect, it can be inverted by changing this parameter. In this menu item, use buttons + and – to
activate and display the two possible states "0" or "1". The phase sequence is shown in the comment line on display. The function is
also enabled when the motor is running.
If it is not possible to see the direction of motor rotation after entering manual mode, proceed as follows:
Start up the pump at frequency FP (pressing MODE and + or MODE + -)
o
Turn on a utility and check the pressure
o
Without changing collection, modify parameter RT and the pressure again.
o
The correct RT parameter is that which generates a higher pressure.

VF: Flow display
If the flow sensor is selected, this enables display of the flow in the selected unit of measurement. The unit of measurement can be
[l/min] or [gal/min] see section 6.5.8. In the case of operation without the flow sensor,

Installer menu
From the main menu, press and hold "MODE" & "SET" & "-" simultaneously until "RC" 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.
6.5.1
RC: Electric pump rated current setting
Rated current absorbed by a pump phase in Amperes (A). For models with single-phase power supply, the current absorbed by the
motor must be set, if powered, by a three phase 230V circuit. For models with three-phase 400V power supply, the current absorbed
by the motor must be set, if powered, by a three phase 400V circuit.
If the parameter entered is lower than the correct value, the error "OC" is displayed during operation as soon as the set
current exceeds the current set value for a set time interval.
If the parameter entered is higher than the correct value, the current sensitivity protection will trip inadvertently over the
motor safety threshold.
On initial start-up and when default settings are restored, RC is set to 0.0[A] and the correct value must be entered;
otherwise the unit will not start and the error message EC is displayed
6.5.2
RT: Setting the direction of rotation
If the direction of pump rotation is incorrect, it can be inverted by changing this parameter. In this menu item, use buttons + and – to
activate and display the two possible states "0" or "1". The phase sequence is shown in the comment line on display. The function is
also enabled when the motor is running.
If it is not possible to see the direction of motor rotation, proceed as follows:
Turn on a utility and check the frequency.
o
Without changing collection, modify parameter RT and check the FR frequency again.
o
The correct RT parameter is that which requires, compared to collection, a lower frequency FR.
o
CAUTION: on some electric pumps, it may occur that there is little difference in frequency in the two cases, and it is therefore difficult
to understand which is the correct direction of rotation. In these cases, repeat the test described above, but rather than checking
frequency, attempt to check the phase current absorption (parameter C1 in the user menu). The correct RT parameter is that which
requires, compared to collection, a lower phase current C1.
6.5.3
FN: Rated frequency settings
This parameter defines the rated frequency of the electric pump, and can be set from a minimum of 50 [Hz] and maximum of 200 [Hz].
Press "+" or "-" to selected the required frequency starting from 50 [Hz].
