minimum differential settable between Pmax and Pmin is 0.3 bar, although it is advisable to keep
it at least 0.5 bar. Use the + and – buttons to alter the parameter setting.

advisable to increase the parameter on this page using the "+" button. If on the other hand you

Pmax2: this page is only displayed if the
CONTACT " parameter is set on "3" (second set-point function);
this parameter is used to set the secondary set-point of the device.
When the auxiliary contact is externally closed the Pmax2 pressure
value becomes the new set-point according to which the Sirio Entry
Pmin: this value represents the pump restart pressure. When any
user appliance is switched on, the pump does not start up until the
system pressure has dropped below the Pmin value. Once the motor
has started running, its rotation speed is regulated to keep the
pressure as near as possible to the value set for the Pmax. The
Stop delay: Use this parameter to define after how many seconds
the motor pump should stop once all the functions have been closed.
If when the flows are low the pump continuously switches on and
off, increase the switching off delay so that the operation is
smoother. Increasing the parameter can also be useful to stop the
Auto-reset interval: if the pump experiences a temporary shortage
of intake water while it is operating, the Sirio Entry cuts off the
power to the motor to prevent it being damaged. From this screen
page, a device automatic restart time can be set (in minutes) at the
end of which a test will be run to see if the intake water supply has
returned. If the test is successful, the Sirio Entry automatically quits
Auto-reset test n.: this parameter sets the number of attempts that
the
Sirio Entry will make to resolve a stop condition due to dry
running. Once this limit has been exceeded, the system shuts down
and the user's intervention is required. If this value is set to zero,
the auto-reset function is switched off. The maximum number of
Maximum number of starts in an hour: From this page you can
set the maximum number of starts of the motor pump in one hour
before the intervention of the Serious Leakage alarm. Only short
starts are counted, in other words those which are not followed by
the suction of minimum 2.5 litres/min of water. If the Serious
Leakage alarm is activated too often or without reason, then it is
