The Gas 320/620 Ace is fitted with an electronic regulation and control
unit. The heart of the control is a e-Smart microprocessor, which controls
and also protects. In the event of an error, a corresponding code is
displayed.
Description
The controls continue to operate, but the cause of the warning must be investigated. A
warning can change into a blocking or lock-out.
The controls will stop normal operation, and will check with set intervals if the cause of
the blocking still exists.
Normal operation will resume when the cause of the blocking
(2)
has been rectified. A blocking can become a lock-out.
The controls will stop normal operation. The cause of the lock-out must be rectified and
the controls must be 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 Remeha.
