The maximum water loss permitted in the system must
be compatible with the residual head of the pump in the
device.
Constant pressure mode
constant (factory set) head mode (rpm) in which the pressure
generated by the pump is maintained constant at the set val-
ue in the entire permitted flow rate range (this mode is indi-
cated for systems with constant losses of load or three-way
bypass valve). This mode is particularly suitable for variable
pressure loss systems with two-way valves.

Variable pressure mode
variable head (Δp-v) operating mode in which the electronic
system varies the head developed by the pump between the
set value and half the set value as the water flow rate var-
ies (this mode is suitable for systems with constant pressure
drops or 3-way bypass valves).
