ADVANCED PARAMETERS:
The advanced parameters are accessible only to the technical assistance service. For access to these parameters, it is
necessary to contact the re-seller, a technical assistance centre or the manufacturer.
The following table lists the advanced parameters for reference when technical assistance is required.

4.0 – Pump stop delay: defines the delay before stopping the pump when
the pressure is the same as the set point and the frequency is below the stop
frequency
.
4.1 – Automatic reset time: if a temporary absence of water on intake is
detected during operation of the electric pump, Nettuno will shut off power
to the motor to avoid it being damaged. On this screen it is possible to set
how many minutes the device will remain stopped before carrying out an
automatic restart to check for the availability of water on intake. If the
4.2 - Automatic reset test no.: this parameter sets the number of attempts
that Nettuno will perform to resolve a stop condition due to dry running.
Once this limit has been exceeded, the system shuts down and the user's
5
intervention is required. If this value is set to zero, the auto-reset function is
switched off. The maximum number of attempts allowed is 20
4.3 - Total automatic reset: when set to ON, the automatic reset function
is active for any error, in addition to dry-running, detected by the system.
Caution: the automatic and uncontrolled reset of some errors (for example,
overload) could over time cause damage to the system and to Nettuno.
OFF
Always take great care when using this function.
