Chapter 8 Fault
8.1 Trouble shooting

The appliance remains in this fault mode until the problem in
question has been solved. Then the appliance will reset itself
(auto reset) and the display will once more show the operatio-
nal mode.
Fault E999
If, when the appliance is powered up directly to message
E999
appears on the display, the mounted control board is not
suitable for this appliance or the dip switches on the control
board are set incorrectly.
For the location of the dip switches see § 10.1.

board are set as shown in the drawing of the dip switches
settings; if they are, and the message E999 still appears, then
replace the control board by a board of the correct type.
Locking fault

work. The (permanently lighted) display shows the fault symbol
(spanner) together with fault code. The red LED on the multiple
switch (if applicable) will be blinking. Contact the installer to
remedy this fault. A locking fault cannot be remedied by taking

(spanner).
