Seethe technical data sheet for user interface compatibility (e.g. BRC1H52*)Note: The user interface will generate a visible and audible warning in case ofrefrigerant leakage detection. E.g., BRC1H52* user interfaces can generate analarm of 65 dB (sound pressure, measured at a distance of 1 m from the alarm).Sound data is available in the technical data sheet of the user interface. The alarmshould always be 15 dB louder than the background noise of the room. In case ofhigher background noise we recommend connecting an external alarm (fieldsupply) to the optional output PCB of the indoor unit. This field supplied alarmmust be mounted in every room where an indoor unit is installed.CAUTION▪ Each indoor unit has to be connected to a separate user interface. Only a safetysystem compatible remote controller can be used as the user interface. Seetechnical 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.
