For installation of the remote controller, please refer to the installation and
operation manual delivered with the remote controller. Each indoor unit has to be
connected with a R32 safety system compatible remote controller (e.g.
BRC1H52/82* or later type). These remote controllers have implemented safety
measures that will warn the user visually and audibly in case of a leak.
For installation of the remote controller it is mandatory to follow the requirements.
1 Only a safety system compatible remote controller can be used. See technical
data sheet for remote controller compatibility (e.g. BRC1H52/82*).
2 Each indoor unit has to be connected to a separate remote controller.
3 Even if multiple indoors are in the same room, they should all have a separate
remote controller.
4 The remote controller put in the same room as the indoor unit has to be in
fully functional mode or alarm only mode. For details about the different
remote controller modes and how to set up, please check the note below or
refer to the installation and operation manual delivered with the remote
controller.
5 Group control is not allowed.
6 For buildings where sleeping facilities are offered (e.g. hotel), where persons
are restricted in their movements (e.g. hospitals), an uncontrolled number of
persons is present or buildings where people are not aware of the safety
precautions it is mandatory to install one of the following devices at a location
with 24-hour monitoring:
▪ a supervisor remote controller
▪
or an iTM with external alarm via WAGO module.
Note: The remote controller will generate a visible and audible warning. E.g. the
BRC1H52/82* remote controllers can generate an alarm of 65 dB (sound pressure,
measured at 1m 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 in a certain
room, we recommend to use an external alarm (field supply) in that room. This
alarm can be connected to the SVS
output channel of the outdoor unit or to the
optional output PCB of the indoor unit of that specific room.
For more information on the SVS output signal, see "20.2 To connect the electrical
wiring to the outdoor unit" [
