Sirio X4 is an interface module that allows the connection of up to 4 Sirio inverters in booster-sets.
The module automatically manages the booster-set by starting one or more pumps according to the demand for water from the system.

In the case of failure of the whole system, an error relay will send an output signal that can be used for an alarm (e.g. for a GSM communicator).

APPLICATIONS: Electronic flow and pressure devices, Variable speed drivers for constant pressure control.
