3.1 Zone addressing in LTE mode
(in conjunction with Synco)
This section applies only to LTE mode.
In cases where RXB Konnex controllers are used in LTE mode (e.g. in conjunction with
Synco) zone addresses need to be allocated. These must be defined together with the
Synco devices at the planning stage.
The zones to be defined are as follows:
Geographical zone
(Apartment . Room Subzone)
Apartment = ---, 1...126
Room = ---, 0...63
Subzone =---, 0...15
Zone in which an RXB Konnex controller is physically
located. Other room-specific devices may also be
located in this zone.
The designations "Apartment, Room and Subzone do
not need to be taken literally. For example, Apartment
can be used to refer to a group of rooms, floor or
section of a building.
"Room", however, really does refer to a room.
Subzone is unlikely to be used much for HVAC devices
it is more relevant to other disciplines, such as lighting
(keep the setting 1).
Timeswitch zone
(Apartment . Room Subzone)
Apartment = ---, 1...126
Room = ---, 0...63
Subzone =---, 0...15
This zone has the same structure as the geographical
zone. It indicates the source of the time schedule for
the RXB Konnex controllers.
The same zone must also contain a device (e.g. a
Synco RMx7xx or RMB795) to deliver the time
schedule.
In a Synco network, "Room" and "Subzone" must
always be set to 1.
Heat distribution zone
heating coil
Zone = ---, 1...31
Information related specifically to the hot water system
in heating coils (heating registers) is exchanged within
this zone. The zone also includes a Synco device to
process the information (e.g. RMH7xx or RMU7xx with
changeover).
Heat distribution zone
heating surface (radiator)
Zone = ---, 1...31
Information related specifically to the hot water system
of a radiator is exchanged within this zone (e.g. heating
demand). This zone also includes a Synco device to
process the information (e.g. RMH7xx or RMB7xx).
Refr. distribution zone
cooling coil
Zone = ---, 1...31
Information related specifically to the chilled water
system is exchanged within this zone (e.g. cooling
demand). This zone also includes a Synco device to
process the information (e.g. RMU7xx).
