7 Fault elimination
7.1 Fault indication
Malfunctions during operation are indicated by a corresponding Warning
or Error message in the display of the control unit:
– Warning messages
The control of the Nordmann AT4 checks whether there is a temporary
problem (e.g. water supply interrupted for a short time) or whether it
can resolve the problem by taking necessary measures. If the cause of
the malfunction disappears of its own accord or if the control can repair
the malfunction, the alarm message will automatically switch off. If the
cause of the malfunction does not disappear even after a longer period
of time, a error message is triggered.
– Error message (additionally to the error message the red LED lights)
Further operation is normally not possible any longer, the unit is blocked.
To eliminate the malfunction see chapter 7.1 and 7.3.
Note: After eliminating the malfunction the error message must be reset
(see chapter 7.4).
By pressing the <Info> key additional information can be displayed for each
warning and/or error message.

message of a humidier on the optional remote terminal, select “Excep
