Wait about 10 seconds before resetting nor-
mal operation conditions.

If just the blinking alarm is displayed it means
that a temporary stop was diagnosed, if the
fault is reset the boiler proceeds with regular
autonomous operation.

ular operations, a definitive lockout can be
brought about. In this case, proceed as de-
scribed in point 2.
2 Red led comes on and blinking alarm
code is displayed
Turn the mode selector (5) to

should contact the r Technical Assistance
Service.
