User interface
The user interface is composed of a key (A), a bi-colour red/green
LED (B) and four yellow LEDs (C) in a line.
The user interface allows you to display the operating performance
(operating status and alarm status) and set the operating modes of
the circulator.
The performances, indicated by the LEDs (B) and (C) are always
visible during the normal operation of the circulator, while the set-
tings are carried out by pressing the key (A).
