| VSP
• To put the VSP in service, press the ON/OFF key on the control panel.
• Having pressed the ON/OFF key ensure the pressure of the system is under the SETPOINT value less the RESTART
DIFFERENTIAL set. Only in this condition can the inverter start the electric pump.
• If the electric pump is not correctly primed, bring VSP to TEST mode (manual operation) and gradually open the supply
valve (for operation in TEST mode, see the corresponding chapter described later in the following manual).
ATTENTION: the inverter is perfectly congured by default settings, to work correctly with the associated elec-
tric pump.
If the VSP default values should be edited, set the inverter using the parameters in the ADVANCED MENU (see the ADVANCED
MENU PARAMETERS chapter)
After making all the electrical and plumbing connections correctly, enter the conguration menu to set the correct parame-
ter values for the kind of operation to be performed by the system.
FUNCTIONING PARAMETERS
• The display on the control panel assumes three dierent types of colours based on the status in which the VSP is found.
– WHITE display if the VSP is found in STAND BY
– GREEN display if the VSP is working regularly (START)
– RED display if the VSP is in alarm mode due to some fault (ERROR)
– YELLOW display if the VSP is found in the PROGRAMMING MENU
• When VSP is regularly working, the display on the control panel turns GREEN and on the display:
