Application 1: room temperature control
This application is ideal for smaller offices and rooms with
only one radiator. The Symaro sensor for flush mounting
measures and controls the room temperature and sends the
positioning signal via the KNX bus to the valve actuator. In com-
bination with a window contact, the sensor can also identify
the current status of a window and transmit it via the KNX bus.

Application 2: room climate control
This application is especially suitable for rooms with several
radiators – for example, in offi ces, lecture halls or confer-
ence rooms. The sensor for fl ush mounting measures the CO
2
value in the ambient air, controls the ventilation based on
demand and so saves energy and costs. In conjunction with
the integrated room temperature control, the sensor ensures
a comfortable room climate. For example, lighting and blinds
can be controlled by means of a conventional double push-
button. Furthermore, it is possible to connect an additional
room temperature sensor, e.g. to calculate a mean value.

Installation note: energetically optimal mounting
To ensure correct measurement of room temperature and thus
energy-efficient operation and the best possible room comfort,
the sensors for flush mounting should be:
– positioned 1.5 m above the floor and at a distance of
at least 50 cm from the door.
– not mounted on exterior walls, in niches or behind curtains.
– not installed within the radiation zone of heat sources,
e.g. light sources.
– not exposed to direct sunlight.
Important note: If an installation conduit is used to install the
sensor, it should be ensured that the device-side end is sealed
to prevent drafts that will affect the sensor’s measurement.
