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.
