NOTICE

Group control connection is NOT allowed.

CAUTION

Each indoor unit has to be connected to a separate user interface. Only a safety
system  compatible  remote  controller  can  be  used  as  the  user  interface.  See
technical data sheet for remote controller compatibility (e.g. BRC1H52/82*).

The user interface has to be put in the same room as the indoor unit. For details,
please refer to the installation and operation manual of the user interface.
