The performance, indicated by the LEDs (B) and (C) is always visible
during normal operation of the circulator whereas the settings can be
carried out by pressing the button (A) (fig. 49).
Operating status indication
When the circulator is in operation the LED (B) is green (fig. 49). The
four yellow LEDs (C) indicate the electrical energy consumption (P1)
as shown in the following table

(*) For the power (P1) absorbed by the circulator see the indications
in the “Technical Data” table.
Alarm status indication
If the circulator has detected one or more alarms the two-coloured
LED (B) will be red (fig. 49). The four yellow LEDs (C) indicate the
