Page 6.0 is displayed if “economy” mode has been chosen on page 5.0 and allows
setting of the percentage reduction value of the set-point.
This reduction will be carried out if digital input I2 is energised.
Page 7.0 If a twin system is used (see Par. 5.6 ), on page 7.0 you can set one of the 3
possible twin operating modes:
Alternate every 24h: The 2 inverters alternate in regulation every 24
operating hours. If one of the 2 malfunctions, the other takes over
regulation.
Simultaneous: The 2 inverters work at the same time and at the same
speed. This mode is useful when a flow rate is required that cannot be
provided by a single pump.
Main/Reserve: Regulation is always performed by the same inverter
(Main), the other (Reserve) takes over only if there is a malfunction of
the Main one.
If the twin communication cable is disconnected the systems automatically
configure as
Single , working completely independent of each other.

Alarms Log
If the system finds any faults it records them permanently in the alarms log (up to a
maximum of 15 alarms). For each recorded alarm a page composed of 3 parts is
displayed: an alphanumeric code that identifies the type of fault, a symbol that
illustrates the fault in graphic mode, and a message in the language selected on
Page 9.0, giving a brief description of the fault.
By pressing the right button you can scroll through all the pages of the log.
2 questions appear at the end of the log:
1. “Reset Alarms?”
Pressing OK (left button) resets any alarms still present in the system.
2. “Delete Alarms Log?”
Pressing OK (left button) deletes the alarms memorised in the log.
