Recommended measures
Restoration successful, but the backup data installed are fewer than those currently present in
the system.
The backup is irregular and cannot be transferred again
Repeat the reset and backup
The backup data are incompatible with the current version of the software; the
restoration is not possible
Repeat the reset and backup
Repeat the reset and backup
The series of backup data is not valid; restoration is not possible
Repeat the reset and backup
The backup has an inadequate identification of the burner and must not be transferred
to the control box
The series of backup data is not valid; restoration is not possible
Define the identification of the burner and repeat the backup
Repeat the reset and backup
Repeat the reset and backup
Repeat the reset and backup
Carry out a reset, check the connections and repeat the backup
Refer to the Modbus User Documentation (A7541)
The control box has been manually blocked (no error)
Carry out a reset; if the error arises repeatedly, replace the control box
No error
Lockout or error due to lack of parameter settings
Redefine the operation mode (parameter 201)
Redefine the operation mode (parameter 201)
Carry out a reset; if the error arises repeatedly, replace the control box
The program stop is active (no error)
Carry out a reset; if the error arises repeatedly, replace the control box
Carry out a reset; if the error arises repeatedly, replace the control box
Carry out a reset; if the error arises repeatedly, replace the control box
