The room and subzone are fixed (room = 1, subzone = 1).
To set the room group at the control unit, the following applies:
Room group
= Geographical zone
(
apartment
. 1 . 1).
The following settings are available in the RXB room controllers:
– Geographical zone (
apartment
).
– Geographical zone (
room
).
– Geographical zone (
subzone
).
For HVAC applications with RXB room controllers, use only the geographical zone
(
apartment
) and the geographical zone (
room
).
Extending the address by the geographical zone (
room
) results in room control by
means of RXB room controllers. This in turn allows for individual operating interventions
(from an operator unit and the control unit via the bus) such as room setpoint correction
in any room or on any device.
For additional division of the geographical zone (
room
), the RXB room controller offers
the geographical zone (
subzone
).
This subzone can be meaningful in lighting installations, e.g. if a geographical zone
(
room
) must be subdivided into two subzones "lighting along window" and "lighting
along hallway".
For HVAC applications, keep the subzone at = 1.
The supplementary labels "
apartment
", "
room
" and
"
subzone
" are predefined by Konnex. However,
apartment
does necessarily denote
an actual apartment.
Each KNX member requires an individual device address, entered in the floor plan
above with D:11x.
The device address in our example was assigned based on the bus topology.
