CHECK

SENSOR OR DUMMY

Attention

The displayed action to resolve the error may only be performed by a service and maintenance engineer.

There are various types of errors:

LOCK OUT ERRORS

When the cause has been removed, these errors

require a reset with the button before the appliance can resume operation.

BLOCKING ERRORS

These errors disappear automatically once the cause of the error has been removed, after which the appliance resumes operation by itself.

The display does not show what type of error has been detected. A comprehensive overview of the errors is provided elsewhere in the

manual (13 "Troubleshooting").

If, as end-user, you find the appliance in an error condition, you may attempt to restart the appliance by

pressing the button

However, if the error returns or occurs several times in a short time you must contact your service and maintenance engineer.

In all modes, the temperature may at any moment drop below the desired temperature. The appliance then enters a heating cycle. This heating cycle is identical (9.3 "The appliance's heating cycle") for all basic operating modes.

Note

Setting and if necessary programming of the basic operating modes are described in the main

menu (11 "Main menu") chapter.
