Moen INS1296A - 8/10 Manuale Utente

Normal Operation: When new batteries are inserted or AC
power is connected or RESET Button is pushed, the lights on
the Printed Circuit Board (PCB) will blink in the following
sequence: Red, Red (with solenoid clicking), Green, Red and
Red. Green light will stay on. When the user enters the sen-
sor beam's effective range, the Red light will flash one time
on battery-operated flush valves and will stay on on AC-pow-
ered models. If the user stays in the effective range for more
than 4 seconds and steps away, the valve will activate (1)

flush cycle. The flush valve unit will automatically reset for
the next user. When the manual OVERRIDE Button is pushed,
the flushing mechanism will be activated without impacting
the mode of automatic operation. On battery powered mod-
els, the Red indicator light flashes when batteries are low.
