Natural ventilation is a safety measure where ventilation is made to a place where
sufficient air is available to dilute the leaked refrigerant such as a large space.
Function
The controller is fully functional. All normal
functionality is available. This controller can be master
or slave.
The controller only acts as leak detection alarm (for a
single indoor unit). No functionality is available. The
remote controller should always be put in the same
room as the indoor unit. This controller can be master
or slave.
The controller only acts as leak detection alarm (for
the whole system, i.e. multiple indoor units and their
respective controllers). No other functionality is
available. The remote controller should be placed at a
supervised location. This remote controller can only
be the slave.
Note: In order to add a supervisor remote controller to
the system, a field setting must be set on remote
controller and outdoor unit. Indoor units and SV units
need to be assigned an address number.
