1.3 Integrated Inverter

The electronic control integrated in the system is of the type with inverter and it makes use of two pressure and temperature sensors (one on
intake and one on delivery).
By means of these sensors the system switches on and off automatically according to the user's needs, keeping a constant delivery pressure.
The system is configured by the manufacturer to satisfy the majority of installation cases, that is:
• Operation at constant pressure;
• Set-Point (desired value of constant pressure):
• Reduction of pressure to restart:
Anti-cycling function:
•
Chapters 8-9-10 show all the parameters that can be set: pressure, intervention of protections, rotation speed, etc.

1.4 Integrated Expansion Vessel

The system is complete with an integrated expansion vessel with a total
capacity of 2 litres.
It is not a function of the integrated expansion vessel to ensure a water
reserve such as to reduce interventions of the system (requests from the
utility, not from a leak in the system). It is possible to add an expansion
vessel with the capacity you prefer to the system, connecting it to a point
on the delivery system (not a suction point!).
The expansion vessel is preloaded according to the following ratio:
Pair= SP-RP-0.2 bar
So, by the manufacturer:
If different values are set for the parameters SP and/or RP, regulate the valve of the expansion vessel releasing or letting in air until the above
equation is satisfied again.
