15.4 Combining units and options
INFORMATION
Certain options might not be available in your country.
15.4.1 Possible options for the indoor unit
Make sure you have the following mandatory options:
▪
User interface: Only a safety system compatible remote controller can be used.
See technical data sheet for remote controller compatibility (e.g. BRC1H52/82*)
Note:
The user interface will generate a visible and audible warning sign in case of
refrigerant leakage detection. E.g. the BRC1H52* remote controllers can generate
an alarm of 65 dB (sound pressure, measured at 1 m distance of the alarm). Sound
data is available in the technical data sheet of the remote controller. The alarm
should always be 15 dB louder than the background noise of the room. In case of
higher background noise we recommend to use an external alarm (field supply) to
connect to the optional output PCB of the indoor unit. This field supply alarm has
to 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 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.
