The boiler is fitted with an electronic regulation and control unit. The heart
of the control is a microprocessor, which controls and also protects the
boiler. In the event of an error, a corresponding code is displayed.
Description
The boiler continues to operate but the cause of the warning must be investigated. A
warning can change into a blocking or lock-out.
The boiler starts up again automatically when the cause of the blocking has been recti­
fied. A blocking can become a lock-out.
The boiler starts up again only when the cause of the lock-out has been rectified and
reset manually.
The meaning of the code can be found in the various error code tables.
Important
The error code is needed to find the cause of the error quickly and
correctly and for any support from De Dietrich.
