correct operating conditions have been restored, the boiler will restart automatically. There
are a maximum of 3 consecutive attempts at a release by the REC10CH. In case of all the
attempts are exhausted the definitive fault E099 occurs on the display. The boiler will need
to be unlock by cutting off and reconnecting the electrical supply.

For fault E060: the appearance of this error, on only heating models with water tank with
probe connected, prevents DHW operation.
For fault E091: the boiler has an auto-diagnostic system which, based on the total number
of hours in certain operating conditions, can signal the need to clean the primary exchanger
(alarm code E091). Once the cleaning operation has been completed, reset to zero the total
hour meter with special kit supplied as an accessory following procedure indicated below:
