Solving problems based on error
codes

When  a  problem  happens,  an  error  code  appears  on  the  user
interface.  It  is  important  to  understand  the  problem  and  to  take
measures before resetting an error code. This should be done by a
licensed installer or by your local dealer.

This  chapter  gives  you  an  overview  of  all  error  codes  and  the
content of the error code as it appears on the user interface.

For a more detailed troubleshooting guideline for each error, please
see the service manual.

Fault diagnosis by user interface

The  user  interface  can  receive  an  error  code  from  the  indoor  unit
referring  to  the  fault.  It  is  important  to  understand  the  problem  and
take measures before resetting the error code. This should be done
by a licensed installer or your local dealer.
