Application examples
Room temperature regulation with operation
Key*
Room control unit QMX3.P34
Presence detector UP 258
Electromotive valve actuator AP 562/02
Window contact S 290
*Possible combination of components
This application is recommended for smaller offices with a single
heater. The room control unit measures and regulates room tempe-
rature and sends the regulation signal to the valve drive actuator via
KNX bus.
In addition to this, window contacts and presence detectors influ-
ence the regulation behavior of the room control unit and increase
the room‘s energy efficiency. For example, if the room is unoccupied
or if the window is open, the radiator valve closes and reduces the
room temperature automatically.

This application is especially suitable for rooms with several heaters,
e.g. in offices, lecture halls or conference rooms. The room control
unit (1) measures and regulates room temperature and sends the
regulation signal to the thermal drive actuator (8) via KNX bus.
Together with the integrated room temperature regulation, the
sensor thus provides for a comfortable room climate. The room
control unit (2) measures the air quality (CO
2
) in the room, regulates
ventilation as required and thus saves energy and costs. The buttons
on the room control unit (1 and 3) can be used to control lighting
and shading as well as scenes for example.
Additional room control units (3) can also be connected, e.g. in
large rooms with several doors.
